5 Technical SEO Mistakes We See Agencies Make (And How to Fix Them)
We've audited over 50 websites built by or for agencies, and the same technical SEO mistakes keep appearing. The frustrating part? Most of these are quick fixes that can dramatically improve rankings.
Mistake #1: Ignoring Core Web Vitals
Google has been clear that page experience matters. Yet we regularly see agency sites with LCP scores above 4 seconds. The fix is usually simpler than people think — proper image optimization, lazy loading, and removing render-blocking resources can cut load times in half.
Mistake #2: Missing or duplicate meta tags
It sounds basic, but we still find sites with the same title tag on every page, or missing meta descriptions entirely. Each page needs unique, keyword-targeted meta tags. It takes an hour to fix and the impact on CTR is immediate.
Mistake #3: Not implementing structured data
Schema markup helps search engines understand your content. For agencies, FAQ schema, service schema, and review schema are low-hanging fruit that can earn rich snippets in search results.
Mistake #4: Broken internal linking
We often find orphaned pages, broken links, and poor site architecture. A clean internal linking structure helps both users and search engines navigate your site. We use custom crawling tools to map these issues.
Mistake #5: Not monitoring after launch
SEO isn't set-and-forget. We set up automated monitoring for all our projects — tracking rankings, crawl errors, and performance regressions. When something breaks, we catch it before it impacts traffic.
