Freshness as a ranking signal
Google uses a freshness signal (Query Deserves Freshness, or QDF) for certain query types. While evergreen informational content is less affected, pages covering tools, software, and web practices benefit from periodic updates because the landscape changes. A page last modified three years ago signals potential staleness, even if the underlying information is still accurate.
How Googlebot crawl frequency works
Googlebot crawls pages more frequently when it has seen the page change in the past. An active site that regularly updates its content trains the crawler to revisit more often, which means new tool pages, blog posts, and redirects get indexed faster. Conversely, a static site can see crawl frequency drop to once a month or less.
What to update and how often
You do not need to rewrite every page constantly. Focus updates where they add real value: refresh screenshots when a tool UI changes, update statistics and examples when the numbers become outdated, add new FAQ items based on questions you receive via the contact form, and expand sections where analytics show high bounce rates or short dwell times.
Updating internal links as you add content
Every time you publish a new blog post or add a new tool, audit existing content for opportunities to add internal links to the new page. A new post about 'How to use schema markup for local businesses' should receive links from your Schema Generator tool page and from any existing blog post that touches on structured data.
Measuring the impact of content updates
Use Google Search Console to track average position and impressions over time. After updating a page, note the date as an annotation in your analytics so you can correlate changes in traffic or rankings to your updates. The Search Console Analyzer tool on this site makes it easy to parse and visualise query exports, giving you a clear picture of which pages benefited most.
