Technical SEO Checklist 2026: Create a Website Designed for Ranking

1. Crawlability 

Providing Search Engines Access to All Important Information

The process for search engine discovery of your site’s web pages is called crawling. If this process does not work correctly, everything else is for nothing.

How To Optimize

• Submitting an XML sitemap via Google Search Console will aid in crawling. 

• Make sure your robot.txt file is clean and optimized. 

• Remove all broken internal links. 

• Use a clean, logical navigation hierarchy. 

Advanced Optimization

• Optimize crawl depth, keeping in mind most users will only click 3 times on a site in order to reach an important page. 

• Remove the use of JavaScript-heavy navigation as this will hinder search engine crawlers. 

• Make sure that faceted navigation does not create infinite URL structures. 

Expert Insight

• If you properly structure your site, it will have less friction when crawling, making it more probable that the search engines will crawl and index your site quicker than your competition.

2. Indexing

 Ensuring Your Pages Are Included In Search Results

There are many instances of websites dropping their rankings due to pages being crawled, but not indexed. 

Checklist

• Check for “noindex” tags on your pages as some may be set accidentally. 

• Consolidate duplicate or near-duplicate pages to the same website page. 

• Utilise canonical tags. 

• Monitor index coverage reports to ensure pages are being indexed. 

Hidden Issues That May Be Present

• Thin content pages will be ignored by crawlers. 

• Parameter-based URLs will create duplicate content. 

• Orphan pages are not linked to from any other pages = no indexed pages. 

Quick Tip

• Find weak content and consolidate into an authoritative, powerful content hub.

3. Site Speed Optimization
