SEO Content Audit: Find Your Underperforming Pages

An SEO content auditis a systematic review of every indexable page on your site to decide what’s working, what’s slipping, and what to do about it. Done well, it turns a sprawling, half-forgotten content library into a clear, prioritized to-do list.

Start with the data that matters

Your primary source is Google Search Console. Export performance by page over the last 3–6 months and compare it to the same window a year earlier. For each page, you want clicks, impressions, average position, and the queries it ranks for. Layer in your analytics for conversions where you can, so you know which pages have business value, not just traffic.

Sort every page into a bucket

The heart of an audit is categorization. Most pages fall into one of five buckets:

• Winners: ranking and converting. Protect these; don’t “optimize” them carelessly.
• Decaying: losing clicks and impressions year over year. Prime refresh candidates.
• Cannibalizing: two or more pages competing for the same query, splitting your authority.
• Thin / no-traffic: little content, no links, negligible traffic.
• Unindexed: pages Google has crawled but not indexed, or never crawled at all.

Decide: keep, refresh, merge, or prune

Each bucket maps to an action:

• Keep & monitor the winners.
• Refresh the decaying pages, update facts, intent, depth, links, and schema, on the same URL.
• Merge cannibalizing pages into one strong page and redirect the rest.
• Prune thin, value-less pages by removing or redirecting them; a tighter site is easier for Google to crawl and trust.

Don’t skip the indexing check

A page that isn’t indexed can’t rank, period. As part of the audit, check which URLs are actually indexed versus “crawled, currently not indexed,” and diagnose why: thin content, duplication, weak internal linking, or crawl issues. Fixing indexing is often the fastest win in the whole audit. Perennial’s indexing audit is built for exactly this.

Make it a cadence, not a one-off

Content audits aren’t a once-and-done project. A light quarterly pass on your top pages plus a deeper annual review keeps decay from compounding. The sites that hold their rankings treat auditing and refreshing as routine maintenance, not emergency surgery.

The goal of an audit isn’t a giant spreadsheet, it’s a short, prioritized list of actions that protects your winners and reclaims the traffic your decaying pages are leaking.
