Website Technical Audit: What's Important to Check

A website technical audit is the foundation of effective SEO promotion. Even the most beautiful and sales-oriented website won't bring in clients if it has technical errors. Regular checks help identify problems and improve search engine rankings.

1. Website Loading Speed
Fast loading is one of the key ranking factors. If a site takes longer than 2-3 seconds to load, users leave, and rankings drop. It's important to optimize images, code, and the server.

2. Mobile Responsiveness
Most users access websites from their phones. The site must display correctly on all devices and work quickly on mobile.

3. Page Indexing
Check if all important pages are being indexed by search engines. Errors in the robots.txt file or meta tags can block the site from Google.

4. Errors and Broken Links
The presence of 404 pages and non-working links degrades user experience and negatively impacts SEO. They need to be found and fixed regularly.

5. Website Structure and URLs
A clear structure and understandable URLs help search engines better understand the site. Page addresses should be logical and contain keywords.

6. SSL Certificate (HTTPS)
Security is an important factor. The site must operate over HTTPS, otherwise users may see warnings about an insecure connection.

7. Page Duplicates
Duplicate content can lower a site's rankings. It's important to set up canonical links and eliminate duplicate pages.

A technical audit is a mandatory step for any website. It helps eliminate errors, improve SEO, and increase the number of clients. If you want to achieve maximum results, it's best to entrust the audit to specialists and fix all shortcomings in a timely manner.
