A site audit isn't a one-time task. It's the monthly check that keeps your Webflow site from quietly accumulating technical problems that hurt your rankings before you notice them.

Most technical SEO issues don't announce themselves. A broken link doesn't throw an error you'll see while browsing. A page accidentally set to noindex won't appear in your analytics. Duplicate title tags across 10 pages won't trigger any warnings in Webflow Designer. These things build up, and the first sign is usually a ranking drop that's already a month old.

A good monthly audit covers four things: crawlability, on-page basics, broken links, and performance.

For crawlability, the Coverage report in GSC is your starting point. Look for pages labeled "Excluded," "Crawled but not indexed," or "Discovered but not indexed." Each status has a different cause. "Discovered but not indexed" usually means thin content. "Excluded" often means a noindex tag is blocking the page.

On-page basics means checking for missing H1 tags, duplicate title tags, meta descriptions over 160 characters, and pages with no internal links pointing to them. These are the classic issues a crawl surfaces. In Webflow, they're straightforward to fix once you know which pages have them.

For broken links: a 404 is a dead end for both users and Google. Screaming Frog (free up to 500 URLs) or SEMrush's Site Audit will find broken internal and external links quickly. Fix them or set up redirects.

For performance: slow pages hurt both rankings and conversions. A quick check in PageSpeed Insights on your top 5 pages each month tells you if anything has regressed. Usually a new image or third-party script added to the site is the culprit.

To run this in 30 minutes: start in GSC, check the Coverage and Core Web Vitals reports, and note any new errors since last month. Then run a crawl with Screaming Frog or SEMrush, filter for 4xx errors and pages with missing meta titles or descriptions, and fix issues in order of severity — indexing problems first, broken links second, on-page errors third.

Log what you found and what you fixed. Over time, that log becomes a record of your site's health and evidence that your ongoing SEO work is producing results.
