Block Fake Googlebot Visits
Checks visitors that claim to be Googlebot with a reverse DNS lookup and blocks the impostors, which are usually scrapers or vulnerability scanners.
Snippet Library
WordPress code snippets, ready to use
3,040 free snippets from the WPIDE team and the community. Copy the code, or add any snippet to your site in one click with WPIDE.
Block IP Addresses That Trigger Many 404 Errors
Temporarily blocks visitors who hit more than 20 missing pages within a minute, a typical sign of vulnerability scanners probing for old plugins and backup files.
Hide Plugin and Theme Versions in Asset URLs
Replaces the ?ver= value on plugin and theme CSS and JavaScript files with a short hash, so scanners cannot read your exact plugin versions from the page source, while caches still refresh whenever a version changes.
Keep Bots Out of Redirection's 404 Log
Stops the Redirection plugin from logging 404s caused by crawlers and vulnerability scanners (wp-login probes, .env and .php file hunts), so the log shows only real broken links.
Rate-Limit the REST API for Visitors
Limits how many REST API requests a logged-out visitor can make per minute and answers "429 Too Many Requests" beyond that, slowing scrapers and scanners.
