A technical SEO checklist helps you find website problems that can stop search engines from reaching or understanding important pages. Work through these checks in order, starting with access and indexing before moving to speed and advanced details.
Technical SEO Checklist: Start With Crawling and Indexing
Technical SEO Checklist for Indexing
Open Google Search Console and inspect a few important URLs, such as your home page, main service page, and newest article. Check whether Google can access each page and whether it is indexed. A successful test does not promise a ranking, but it can show clear access problems.
Check that important pages return a normal success response. A page that shows a server error, an unwanted redirect, or a soft 404 needs attention. Also check that pages you want indexed do not have a noindex rule.
Use the report to find patterns. If many pages fail for the same reason, fix the shared cause first instead of asking Google to index every URL one by one.
Check Site Structure and Internal Links
A clear site structure helps visitors and crawlers find important content. Group related pages under sensible categories, use short descriptive URLs, and link from relevant articles to key guides.
Find important pages that have no useful internal links pointing to them. These are often called orphan pages. Add links from relevant pages rather than adding every link to every article.
For EarnSpot, a technical article should point readers to the detailed guide that solves a specific problem. For example, link to the existing JavaScript SEO guide when discussing content that depends on JavaScript.
Review Redirects and Canonical URLs
Make sure common URL versions lead to the correct page. HTTP and HTTPS versions, www and non-www versions, and old page URLs should not split the same content across many live addresses.
Use a permanent redirect when a page has truly moved. Avoid long redirect chains and loops. Update internal links so they point to the final URL.
A canonical tag tells Google which URL you prefer when similar pages exist. It is a signal, not a command. The canonical should point to a useful page with matching content. Do not point a page to an unrelated URL or mix conflicting signals without a reason.
Check Your XML Sitemap and Robots.txt
Your XML sitemap should list the URLs you want search engines to discover. Remove URLs that redirect, return errors, or should not be indexed. Submitting a sitemap helps discovery, but it does not force Google to index every URL.
Review robots.txt to make sure it does not block key pages or resources that Google needs to render them. A robots.txt block is not the same as a noindex rule. Use the right method for the problem.
After a fix, test a sample URL in Search Console. Keep a note of what changed and when, so you can review the result later.
Review Mobile Experience and Page Speed
Open key pages on a phone. Check that text is easy to read, buttons work, forms can be completed, and important content is not hidden behind broken menus.
Use PageSpeed Insights to check real field data when available and lab test results. Core Web Vitals focus on loading, responsiveness, and visual stability. Fix large images, heavy scripts, slow server responses, and layout shifts that affect real visitors.
Do not install multiple performance plugins that do the same job without a test plan. Make one change at a time, clear cache when needed, and recheck the same URL. See EarnSpot’s guide to Core Web Vitals for a deeper explanation.
Check Structured Data and JavaScript
Structured data can help search engines understand page details. Use only schema that fits the visible content and current Google rules. Test it with Google’s Rich Results Test when the feature is supported.
If key content loads through JavaScript, check that Google can see the main text and links. A page may look correct in your browser while important content is missing from the rendered HTML. Our JavaScript SEO article covers common problems.
Schema does not guarantee higher rankings or a special search result. Treat it as a way to describe real page information, not as a shortcut.
WordPress Checks That Save Time
Review your SEO plugin settings for accidental noindex rules, wrong canonical URLs, and sitemap options. Check a few live page URLs rather than assuming that a green plugin indicator means every technical item is correct.
After changing a slug, update internal links and set a redirect from the old URL if that URL was live. Before removing a plugin, check whether it provides redirects, schema, or other features your site still needs.

A Simple Audit Workflow
- First, check crawling, indexing, server errors, and noindex rules.
- Next, check redirects, canonicals, sitemaps, and internal links.
- Then review mobile use, Core Web Vitals, JavaScript, and structured data.
- Write down each issue, its affected URLs, its priority, and the fix owner.
- Retest a sample after each fix and record the date. Do not change many items at once if you need to learn which change helped.
Common Technical SEO Mistakes
- Assuming that sitemap submission guarantees indexing.
- Blocking a page with robots.txt when the real aim is to keep it out of search.
- Pointing canonicals to pages with different content.
- Creating redirect chains after changing URLs.
- Adding structured data that does not match the visible page.
- Fixing a plugin score while ignoring real crawl and index problems.
Prioritize Fixes by Impact
Not every issue needs the same speed. Fix problems that block many important pages first. Then work on details that affect fewer pages or have less effect on the visitor.
- Urgent: Key pages return errors, use noindex by mistake, or cannot be reached by Google.
- High: Important pages point to the wrong canonical, loop through redirects, or have no internal links.
- Medium: Pages load slowly, images are too large, or mobile buttons are hard to use.
- Low: Small tidy-up tasks that do not block access or hurt the visitor.
This is a work plan, not a Google ranking formula. Write down the URLs affected, the fix, and the person who will do it. Retest the same URLs after the change.
Practical Example: Run a WordPress Technical SEO Check
Imagine a service page is not appearing in Google. Do not change the page at random. Follow a small, repeatable check so you can find the cause and record what you changed.
- Open the page in Google Search Console URL Inspection and check the last crawl, indexing status, and any reported issue.
- View the page source or use an SEO plugin to confirm it does not have an accidental noindex directive and that its canonical points to the correct URL.
- Test the URL response. Fix server errors, redirect loops, broken internal links, and links that lead to outdated URLs.
- Check that the page is eligible for indexing and included in the XML sitemap if it is a canonical page you want Google to find.
- Test mobile usability, Core Web Vitals, and any structured data that applies. Validate changes, then request indexing when appropriate.
Keep an audit sheet with the URL, issue, evidence, priority, fix owner, and recheck date. A technical change is not complete until you confirm that the page still works and the problem has actually been addressed.
Final Thoughts
A technical SEO checklist works best when it starts with access, indexing, and URL problems. Then move to links, speed, and structured data. Keep a record of every change and use Search Console to check what happened. A clear process helps you fix the largest problems first, but no checklist can promise a ranking.
Frequently Asked Questions
Technical SEO helps search engines discover, crawl, interpret, and index the important pages on your website. It covers items such as status codes, internal links, canonicals, sitemaps, robots directives, structured data, and site performance.
Check important pages and reports regularly, and run a broader review every few months. Audit after a redesign, migration, major plugin change, URL restructure, or sudden indexing decline.
No. It removes barriers and helps search engines understand the site, but rankings also depend on relevance, content quality, competition, and other factors.
No. Plugins can help with titles, metadata, canonicals, sitemaps, and some schema. They cannot automatically fix every server, theme, hosting, JavaScript, or internal-link problem.
Usually not. A sitemap should generally list canonical URLs that you want search engines to index. Investigate conflicting noindex, canonical, and sitemap signals rather than leaving them inconsistent.
