Crawlability

You can have the highest quality and valuable content, but it is useless if search engines cannot crawl your pages. The first step of your technical SEO audit is to check your robots.txt file. This file is the search engines first point when it comes to crawling your site. Your robots.txt file outlines what pages should and should not be crawled, using an “allow” and “disallow” feature.

You can find your robots.txt file by visiting yourwebsite.com/robots.txt. Test the file in Google Search Console, ensuring it is crawlable without errors.

Indexability

Now you know Google can crawl your site, you need to ensure the search engine is indexing your pages. You can do this by:

• Google Search Console coverage report – status of your web pages including 404 redirect issues, pages that have successfully been indexed, along with pages that have been indexed with warmings against them 
• Screaming Frog – free version has a crawl limit of five hundred URLs. This tool provides you with information on whether your URL is indexable, along with indexability status, when the URL is non indexable, helping you make the necessary adjustments.

Sitemap Review

• Formatted in an XML document
• Follow XML sitemap protocol
• Only include canonical versions of URLs
• Update as new pages are added

Mobile Friendliness

Page Speed Audit

Duplicate Content

Visit Google Search and type in “info:www.yourwebsite.com.” On the last page of results, it will tell you if there is any duplicate content issues, highlighted as a duplicate content warning.
