A single broken link can cost you a customer. A slow page can lose you a sale. An expired SSL certificate can scare away visitors. Most website owners know their site has issues finding them is the hard part. Here are the 10 most common technical SEO problems, why they matter, and how to check for them in minutes.
Links that point to pages that no longer exist. Every broken link is a dead end. For e-commerce sites that means lost sales. For blogs it means lower reader retention. Fix: run a scan and update every link returning 4xx or 5xx.
How long your page takes to fully load. Google treats load time as a ranking factor. A page taking over 3 seconds loses more than half its visitors. Fix: check server response time and optimise.
Loading scripts or images over HTTP on an HTTPS page. Browsers block mixed content. A single HTTP resource can break your page layout. Fix: upgrade all resources to HTTPS.
Visitors can access http:// without redirecting to https://. Google prefers HTTPS. Fix: configure a 301 redirect from HTTP to HTTPS.
Missing X-Frame-Options, HSTS or X-Content-Type-Options. These are basic web security protections. Fix: add them to your server configuration.
A URL that redirects multiple times before reaching the final page. Each redirect adds latency. Fix: replace chains with a direct 301.
No instructions for search engines. Without a sitemap new pages may take weeks to be discovered. Fix: create both and submit to Google.
Browsers show full-screen security warnings for expired certificates. Most visitors leave immediately. Fix: renew at least 30 days before expiry.
Internal links pointing to 404 pages or redirect loops. They waste page authority and hurt user experience. Fix: update or remove broken internal links.
When a domain expires your entire site goes down. Traffic, emails, rankings everything. Fix: renew at least 30 days before expiry.
