SEO Mistakes That Kill Website Rankings
Most ranking drops aren't caused by an algorithm update — they're the result of accumulated technical and content mistakes nobody checked for months. Here are the ones that show up most often on .uz sites.
Cannibalization: when a site competes with itself
Keyword cannibalization happens when two or more pages on a site are optimized for the same search query. Google ends up choosing which one to show, and often switches its choice between updates — both pages get unstable, weak rankings instead of one page consistently holding the top spot.
You can spot cannibalization in Google Search Console: in the Performance report, filter by a query and check how many distinct URLs got impressions for it over the last three months. More than one is a signal to investigate.
The fix isn't deletion — it's redistribution: pick the primary page for the query, then either merge the others into it with a 301 redirect or reorient them toward related-but-distinct queries and add an internal link to the primary page.
Duplicate content: obvious and hidden
Obvious duplicates are identical or near-identical text across different URLs: www vs. non-www versions, trailing slash vs. no slash, sort parameters vs. none. Without a correct canonical tag, Google indexes every variant as a separate page, diluting equity and confusing the system.
Hidden duplicates are trickier: product pages using the same manufacturer description copied unchanged across hundreds of catalog pages. Google may not technically classify this as duplication, but from a content-quality standpoint it's thin, low-value text that drags down the section's overall rating.
To check: use Google's 'site:' operator with a quoted text fragment to see every indexed copy. For a large-scale check, run Screaming Frog's near-duplicate content analysis with a 90%+ similarity threshold.
Redirect chains and broken links
A chain of several 301 redirects in a row (A → B → C → D) slows down crawling and gradually loses a fraction of passed equity at every hop. The correct practice is to redirect A directly to D, with no intermediate steps.
Broken internal links (404s) are especially damaging when they come from high-equity pages — the homepage, or a footer present on every page of the site. One forgotten footer link to a deleted section can create hundreds of crawl errors at once.
A regular technical audit via Screaming Frog or the Page indexing report in Search Console should be a scheduled task, not a one-off — at least quarterly for a mid-size site, monthly for a large, frequently changing catalog.
Slow mobile rendering and Core Web Vitals
Google has used mobile-first indexing since 2019 — it evaluates the mobile version of a site as primary, even if the desktop version is faster and more polished. Heavy uncompressed images, synchronous third-party scripts (chat widgets, analytics counters without async/defer), and no caching are the three main causes of poor Core Web Vitals on local sites.
Specific thresholds: LCP (Largest Contentful Paint) should be under 2.5 seconds, INP (Interaction to Next Paint, which replaced FID in 2024) under 200 milliseconds, and CLS (Cumulative Layout Shift) under 0.1. Check against real user data in the Core Web Vitals report in Search Console, not just PageSpeed Insights lab tests — the two can diverge.
Content mistakes people underestimate
Thin content — pages under 150-200 words with no clear commercial purpose (an informational page, not a product listing) — routinely gets hit during content-quality updates, including the logic carried over from historical Panda-style updates into current ranking systems.
Outdated content that's never refreshed loses rankings gradually, especially in topics where currency matters — pricing, regulations, technology. Show a last-updated date and actually update the facts, not just the date stamp — Google can detect a cosmetic date change with no real content changes behind it.
Headlines that don't match content (clickbait for CTR) boost search clicks short-term but increase bounce rate and time-to-pogo-stick — both signals hurt the page's long-term rankings.
