Key elements of a technical SEO audit service?
Crawlability & Indexing__ A strong crawlability and indexing setup focuses on fast page discovery, better index coverage, and stable search rankings.
It is crucial that the sitemap is updated and error-free, which is achieved through the robots.txt file and XML sitemap. The internal linking structure also directly impacts crawlability, which can be improved by correctly using URL parameters, avoiding duplicate URLs, and using canonical tags.
URL Structure & Site Architecture__ URL structure and site architecture are key elements of technical SEO audit service, focusing on making the website’s structure clean, logical, and well-organized so that Google bots can easily crawl, understand, and rank the pages. An ideal URL is always simple, meaningful, and keyword-relevant, so that users can understand the page’s topic just by looking at the URL.
Error Handling & Redirects__ Error handling and redirects are elements that directly impact website health and user trust. The most common issues are 404, 500, 502, or 503 errors, which occur when a page is deleted or a URL is changed without proper redirection. To solve redirect problems, the correct use of 301 (permanent) and 302 (temporary) redirects is crucial to prevent the loss of page authority.
Mobile-Friendliness__ Mobile-friendliness has become a non-negotiable element because search engines follow mobile-first indexing, meaning they prioritize the mobile version of a website since users read blogs more often on their mobile devices. Heavy images, unnecessary scripts, and unoptimized CSS files slow down mobile pages. Therefore, image compression and a lightweight design are essential. The text should be easily readable without needing to zoom in.
Duplicate Content & Canonicalization__ Duplicate content and canonicalization are critical areas of technical SEO that often go unnoticed. This usually happens due to URL parameters, filters, pagination, HTTP vs HTTPS, www vs non-www, or trailing slash issues. The most effective solution to this problem is the correct use of canonical tags, which ensures the website receives clear indexing signals and maintains stable rankings.
