These two elements need to be verified and have to be set up, which is an easy task. Its suggested that the setup and verification is done for the desktop and mobile device of your site.
Additionally, you can consider to set up and get yourself acquainted to some tools which support the auditing purpose which goes well with a big website having several features and functionalities.
- Screaming Frog
- Deep Crawl or Botify
- Google Page Speed Insights
- GT Metrix
- Varvy Pagespeed
- Chrome > Firebug
- Structured Data Testing Tool
These tools serve most purposes, and there are other tools which fulfill the auditing aspects which are a part of the checklist.
FIND AND ELIMINATE SEARCH ENGINE CRAWL BARRIERS
Crawl barriers, implies the things which happen on your site, which hinder the crawling process to fetch the index of the site to the Google’s search results.
Removing the crawl obstacles from your site is an important step from SEO perspective regardless if a site has issues arising or not.
Even if your website has beautiful content, if you are contributing directly or indirectly preventing or hindering the path of search engines from crawling and indexing it, no matter what quality the content is the results are not fetched until the obstacles are removed.
- Most frequent/impactful issues:
- Robots.txt file disallow
Avoid hindering any directories or pages that you shouldn’t be via your site’s /robots.txt file. These directives pass instructions to Google as to which parts of the site they could not crawl into.
For instance if you are hindering a key area,you need to remove that blocking file for the crawling process to take place smoothly.
The best way to test this is with Google’s Robots.txt tester within Google Search Console.
Meta Noindex, Nofollow tag
- Be cautious when using a Meta Noindex, Nofollow tag within the page’s HTML head section on your webpages, especially if they are supposed to be indexed. The noindex, nofollow tag tells Google not to index the URL or follow any of the links.
- If you’re using this elsewhere, you have to get rid of it to have your site’s content to be indexed.
- You can check this with Screaming Frog and/or Deep Crawl.
Internal linking / breadcrumbs
- Make sure that you are linking to all pages that need to be indexed either via navigation, contextual internal links, or breadcrumbs. Search engines crawl links on your site to capture information, so if you’re not linking to something, they cannot fetch the information.
- If not, maybe you need to reconsider your site’s architecture and/or look for opportunities to link to key pages contextually. The most important pages on your site should be no more than a few clicks away from the homepage.
- You can check this with Screaming Frog and/or Deep Crawl.
- Ensure that your site’s important links doesn’t have a rel=nofollow attribute. This attribute prompts the search engines to not to follow the link.
- Every site must have an XML sitemap
- Every site’s XML sitemap must be submitted to search engines.
- All XML sitemaps must be internally or externally linked to from a site’s robots.txt file.
- XML sitemaps must contain all valid URL’s on the site (e.g. those that don’t return an error).
- XML sitemap must contain fewer than 50,000 URL’s, and the file size must be less than 5 MB in size.
Here are some other potential issues:
- Blocked resources: Are you blocking your site’s CSS and JS files from being crawled? If so, here’s why you shouldn’t. You can see this in Google Search Console.
- Broken links or web crawl errors at key access points: Does your site have any broken links within key access points of navigation such as main or secondary navigation? You can check these in Screaming Frog, Deep Crawl, or in Google Search Console’s Web Crawl Errors report.
- Pages restricted by cookies, logins, or forms: Is any key content hidden behind cookies, logins, or forms?
- URL parameter handling in Google Search Console: Did you accidentally set the wrong setting for your parameters in Google Search Console?
- Page rendering: Is Google having trouble rendering your site’s content? You can track this using the Fetch and Render tool within Google Search Console.
Any one of these problems affect the site’s ability to get crawled and indexed, so it’s very crucial to organize the tabs on such types of things for a long term basis.
ENSURE PROPER HTTP STATUS CODES ARE SERVED
Apart from removing the crawl barriers, make sure that you are sending the right codes to search engines on a page-by-page, resource-by-resource basis is crucial for crawling and indexing to happen correctly.
200 “Okay” Status
All live assets including HTML pages, CSS & JS files, images, etc. should serve a 200 “Okay” status to search engines. Its primary purpose is to prompt search engines that the URL/file in question is live and credible.
301 and 302 Redirects
Fundamentally, there are two basic types of redirects in play namely the 301 and 302 redirect.
A 301 “Permanent” redirect indicates the search engine, that the initial URL has shifted perpetually to a new address and cannot revert back.
A 302 “Temporary” redirect indicates a search engine that the initial URL has been shifted for the time being to a new location, and the original URL will be back to use in the near future.
Some redirect guidelines must be followed to meet the SEO standards.
- Uniformly use a 301-redirect when a page is shifting perpetually.
- Consistently use a 302-redirect only when the initial page doesn’t respond anymore.
- Redirect the sequence of chains (e.g. page A > page B > Page C), which is a sequence of redirects with several “hops” before it reaches destination.
- Shun redirect loops (e.g. page A > page B > page A), which is a sequence of infinite loop that redirects.
- Evade usage of Meta Refresh, rather use 301 redirects.
- Wherever it’s possible, to boost the crawl efficiency, update old URL’s to new when the location of the initial URL has been redirected
404 “Not Found” Status
All pages or files that no longer valid or exist must prompt a 404 “Not Found” status code. 404 Errors as occur frequently happen when a page which was once live is deleted or gets redirected to a new location.
You can look for site’s 404 errors either by running a site crawl in Screaming Frog or Deep Crawl, or by looking at your Crawl Errors report in Google Search Console.
Google told earlier that 404 errors don’t hurt your site, and while it’s valid truth, some technical issues could arise, process issues in terms of page retirement, which leads to a bad user experience if the configuration is not done right.
Also if a high-value page gets deleted, failing to redirect to a relevant counterpart implies that any historical data will not be held which affects the page’s behavior.
Here are some things to watch out for with 404’s:
- Make sure that when a page is missing, it redirects to a proper 404 response code rather than another status such as 200 (which are called Soft 404’s).
- Always serve errors using a Custom 404 Error Page to inform the users as what has happened they were previously accessing, also to keep a user within the site experience.
- When a page shall be removed, if there is a close or exact-match counterpart, redirect to 301-which is from the old page to the existing.
- To boost crawl performance and enhanced user experience, find the missing or broken links in the site as a result of 404 errors and update them to go to an relevant accessible URL.
500-Level Status Codes
500-level response codes imply that problems arise at the server level. If your site is returning these response codes, it could mean that there’s a defect with the server.
Such types of bugs frequently occur when a site is down currently or when certain elements of the site are not available currently. You can check if any of such issues have occurred in Google’s Crawl Errors report.
While such a situation is unexpected, Google suggest or recommend serving a specific 500-level response code when your site has decided to be down on maintenance.
They suggest using the 503 “Service Unavailable” response to avoid bad problems as a result of a crawler in order to reach the page while it’s low for maintenance. This status code indicates search engines that the service is down temporarily and the page shall be active soon.
There are other significant HTTP status codes to get acquainted with, these are the important one for many SEO’s and developers.
OPTIMIZE YOUR ON PAGE CONTENT’S SETUP
Till now we discussed what could be done to make sure that your site’s content is monitoring, crawled relevantly, and prompting the correct signals to Google. Now comes the picture of the setting up the actual pages, to make them SEO-friendly .
Following are few guidelines to be followed on a page-by-page basis.
Must and should your URL’s structure must be in all lowercase, and (while allowed) must avoid uppercase, as URLs are case sensitive and can hinder with direct traffic.
- Use the page’s targeted keyword in the URL (e.g. example[dot]com/on-page-seo
- Segregate the keywords using dashes than underscores or spaces.
- Keep your URL’s short & simple; too long URL’s my look spammy to users and search engines (e.g.example[dot]com/seo-is-literally-the-best-thing-in-the-history-of-ever-in-2017-you-get-the-picture)
- Restrict the usage of parameters or otherwise ugly URL’s (e.g. example[dot]com/page=1234&color=blue)
- Restrict usage of unnecessary directories (e.g.example[dot]com/articles/english/2017/09/08/seo-is-the-best)
- Avoid using non-escaped ASCII characters
Page Title Tags
Your page’s title tag is a crucial aspect of SEO ranking. Because every page’s title is clearly visible in your browser or in the code.
- Make sure you don’t miss title tags,make sure that every page on the site has active or valid titles.
- Ensure that every page has a title tag value that is 100% exclusive.
- Title tags must describe the page title tags in short and clearly.
- It’s best practise to attach every page’s individual targeted keyword(s) in the page title, avoid stuffing of keywords.
- Begin your sentence using your target keyword(s) at the very beginning of the title tag.
- Make sure to include your brand name in your title tag, preferably at the last.
- Avoid title tag that are very long — 60 characters is the maximum size. Moz supports a great title tag length preview tool.
- Avoid title tags which are very short (under 30-40 characters), also the space is counted and you want to make the best out of it.
- Avoid usage of values in the title tag that provide no value of information.
- Avoid repetition or boilerplate titles
- Meta Description Tags
- Your page’s Meta Description tags, is not the basis for the ranking , but still it’s important to optimize. Why? As they use it to describe in the search results, which implies that a well-written Meta Description has a positive impact on user click through rates from SERP’s.
Evade missing of any Meta Descriptions,make sure that every page on your site has valid
Meta Description tags
- Ensure that every page has Meta Description content that is 100% different.
- Meta Descriptions must describe in few sentences as few as 1 to 3 sentences.
- Always include every page’s individual targeted keyword(s), but don’t stuff too much keywords.
- Avoid Meta Descriptions which are very long. 160 characters is the maximum cut off point.
- Avoid Meta Descriptions which are very short (under 100 characters), as the space is valuable and you want to make use of it
- Avoid repetition. or boilerplate Meta Descriptions
- There are around six heading tags which are visible on a web page's (H1, H2, H3, H4, H5, H6). H1 tags are most important in the SEO perspective.
- Heading tags have the most critical pieces of important content in a webpage and is often broken into chunks of information for readability.
- All pages must have one H1 tag.
- It’s not suggested to have multiple H1 tag in any webpage.
- Preferably, the page’s first headings must be H1.
- The page’s H1 must include the targeted keyword(s).
- H2’s – H6’s can be used several times in a page depending on the sub headings, it must be used to break the content to organize the areas of a web page.
- It’s acceptable to use target keyword(s) within H2-H6’s tags as long as it’s not considered spam.
Apart from other areas of optimization, the most overlooked area is the actual on page content. It comprises of headings, images, links, text etc.
- Pages which are too long (1,900-2,000 words) tend to secure better SEO rankings according to a recent study.
- Write engaging and innovative content that is written in the user’s perspective and then search engines.
- Also, consider using Latent Semantic keywords within your page’s copy.
- Include images, videos, graphics within the content to give enriched user experience.
Internal & External Linking
As mentioned previously in SEO for Beginners guide, linking is essential for search engines to know the pattern of how they crawl on the web. Search engines make use of links to find content, and use links to gain popularity.
It’s utmost important to ensure that your site and it’s pages are well-linked.
- All pages must have a minimum of one link directing them to other pages for discoverability purposes as you wish to avoid any orphaned pages which have no links pointing.
- The most critical pages on your site must not be more than very few clicks away from home page.
- Your fundamental & secondary navigation should be clear & well-structured.
- You must include plenty of contextual links within your page’s body content.
- Don’t refrain yourself, use internal links such as 2-3 times per article.
- Links must comprise of descriptive,contextual, & keyword-rich.
What does structured data mean?
Structured data is a standardized approach to provide what’s the information on a page and segment the page based on the content. Google and other search engines try hard to figure out the content on a page, you must provide some clues to inform the meaning of a page.
Search engines use structured data algorithm to figure out the content of the page and to collect data.
Also, search engines use structured data to enhance special search result features and enhancements. For instance, a page describing the recipe along with structured data has more chances to be visible in a graphical search result.
Social Media Buttons & Tagging
While social signals don’t contribute directly to the Google’s search ranking algorithm, which makes its work easy for users to share your content and gain visibility of the site which directly impacts the ranking.
According to a recent study, the usage of social sharing buttons promotes upto 7x more clicks. But sadly having social sharing buttons as well as social markup has been overlooked which has impact on the SEO.
- Make sure all pages having social sharing buttons that are displayed clearly and must be known how to use.
- To keep a track of the flow of information shall be presented when using social media platforms. Ensure all pages use valid Open Graph markup, and make sure all the components are well configured.
While it’s not directly does not contribute to the SEO success, it’s evident that good HTML sitemaps are helpful in promoting crawlability, distributing equity across key site pages, also linking the pieces of content.
- HTML sitemaps must be accessible across all pages – typically via a site-wide footer link
- Should be well structured by site section.
- Must include links to top-level sections.
- Should NOT include links to every page on site (save that for the XML sitemap), unless the site is very small.
- Do not include broken or missing links to redirect the pages.
ELIMINATE AND CONSOLIDATE DUPLICATE CONTENT
Duplicate content refers to URL’s with chunks of content that either match or appear the same. Duplicate content implies to the pages within your site and the external pages.
Google doesn’t charge for duplicate content but it impacts the SEO performance.
Duplicate content can:
- Potentially water down the performance of a given URL by splitting the page’s value up across multiple URL’s rather than a single page. Hypothetically, if page A has 50 links, and a duplicate page B has 50 links, they may not perform as well individually as a single page with 100 inbound links.
- Duplicate content affects the Google’s crawl budget – the number of URLs Googlebot can and wants to crawl – for your site. This is primarily a problem for websites that are huge when compared to the smaller ones.
Here’s how to fix duplicate content across your site:
- Make sure that all versions of any given URL on your site direct to the 301-redirect to a single location as opposed to multiple (e.g. http, https, www, and non-www versions of a URL should all redirect to a single preferred location).
- Arrange a preferred version of your domain in Google Search Console.
- Ensure every page has canonical tags, and that canonical tags point to the preferred absolute URL of a given page. Most canonical tags will be self-referencing. And remove duplicate Page Titles across the site.
- Avoid duplicate Meta Descriptions across the site.
- H1 tags must be restricted to single.
- Avoid duplicate throughout the site.
OPTIMIZE ALL DIGITAL MEDIA INCLUDING IMAGES AND VIDEO
Apart from optimizing your site from a crawlability and page structure perspective, it’s critical to optimize your digital media such as images, videos, etc.
The reason optimizing your digital media is important is three-fold:
Google and other search engines cannot look out for an image or video and grab the meaning of the image or video without some sort of contextual description. Images and videos must be well optimized. Images and video contribute to boost the user experience and engagement
Optimizing your site’s images and video’s is simple:
- Ensure the images and videos are well described.
- Make sure that the file-naming follows the same conventions as URL-based best practices, as the file-name will be part of the URL when published.
- Make sure that every images has Alt Tag attributes that are descriptive, correct and provide value.
- Not suggested to embed important text within images.
- Incorporate some small captions for images and videos within your web page.
- Crawl your site for broken images (e.g. 404 errors) and try to resolve them.
OPTIMIZE FOR ALTERNATIVE LANGUAGE/GEO-TARGETING
If your site provides content to other users in several other languages or other regions, it’s a must to mention the version of the content being used.
How to optimize for language or geo-region:
- Along with your primary site, consider housing a version of your site on a Country Code Top-Level Domain (also called a ‘ccTLD’). ccTLDs which tells to which specific geographic locations the user belongs to. For ex: au denotes Australia.
- Use rel=alternate hreflang=x tags to mention if a page on your site has any other alternative-language. This helps Google to send the valid version of the page based on The URL.
- Use Google Search Console’s International Targeting settings which serves as a basis to understand which country a URL belongs to and must be targeted.
HAVE A MOBILE PAGE SETUP STRATEGY
Today mobile device is a must and having a proper mobile strategy is good. The key is that even to date many companies do not have a suitable mobile strategy. In the SEO’s perspective, mobile SEO or responsiveness gains more ranking according to Google.
Here’s how to optimize for mobile at the most basic-level:
- Make sure that your site has at least one of three mobile design components such as Responsive Design, Dynamic Serving, or Mobile-Separate.
- Use Google Search Console’s mobile usability reporting to understand.
- Whether your site’s pages are designed responsive features such as wider screen, clickable elements which are very close, text information that’s small to read etc.
“Nice-to-Have” mobile strategies
If you’re looking for sophisticated or highly advanced or “nice to have” strategies, consider the following:
- Use Accelerated Mobile Pages (AMP’s)
- Usage of App Indexing and Deep Linking if you have an app to enable app content which displays in the Google SERP’s of your webpages.
IMPROVE SITE SPEED TO 3 SECONDS OR LESS
A website’s speed is the most neglected aspects of SEO strategy.
Google has repeatedly said that users are patient enough to wait till 3 seconds. And if a page takes longer than 3 seconds the performance of a site is considered poor and users quit.
Google has come up with a useful tool to figure out the amount of traffic the site is losing the valuable customer only because of the low speed.,However efforts are put to substantially reduce the loading speed and cut down the time of loading.
Best site speed tools
Some of the best tools to keep a track of the site speed:
- Google Page Speed Insights.
- GT Metrix
- Varvy Pagespeed
Most common site speed issues
While there are several complexities, the most frequently happening problem which affects the page loading in desktop and mobile device are:
- Number of calls you get from your server.
- Not using Gzip to transfer the files across the network
- Your server response time
- The overall size of your web page which is primarily impacted by: the # of images you have per page, the size of each image, how effectively the images are optimized so that the loading time is compressed or reduced.
- How effectively you’re using browser caching to store static resources on your user’s local devices, thus slowing doen the secondary page load times.
- Usage of lack thereof) of a Content Delivery Network.
- Usage of (or lack thereof) of HTTP/2.
While there are other components that affect the pagespeed, targeting on these areas does significantly improve your site’s load times.
ENSURE SITE SECURITY AND PROTECT USER INFORMATION
Google has been pushing for increased site security for several years, with their initiative really coming to the forefront in their 2014 “HTTPS Everywhere” presentation.
Making sure the website has well or good security is mainly achieved by encrypting or coding the information via the HTTPS (Hypertext Transfer Protocol Secure). HTTPS is an internet communication protocol which secures the data and transactions that happen between a user and a site. Users prefer a secure and safer experience when accessing a website.
Best practices for implementing HTTPS on your site:
- Get genuine and secured certificate from the hosting provider (minimum of 2048-bit key)
- Make sure that you enforce an HTTPS URL preference via 301 server-side redirects across every pages of the site.
- Ensure that you frequently update all internal links on your site to point to HTTPS rather than HTTP.
- Ensure that you don't block the HTTPS version of your site from being indexed either via the robots.txt file or non index tags.
- Setup the HTTPS version of your site in Google Search Console.
- Watch out for security issues that must be reported via Google Search Console including threats, virus, malware, deceptive pages, harmful downloads, etc.
