They run on your site and send nothing to us.
Search visibility
Pages a search engine cannot show: marked noindex, closed in robots.txt, or pointing to another address.
Redirects
Old addresses to new ones, with patterns and a hit counter. Imports your rules from Redirection and Rank Math.
Broken links
Links in your posts and pages that lead to a missing page of your site, fixed in the post or with a redirect.
404 log
Which missing addresses visitors and bots ask for and how often, with a redirect in one click. No IPs kept.
Content check
Posts that are very short, untouched for two years, without an image or links, or that share a title.
Headings
Pages with no main heading, with several, or with a level left out. Read from the finished page, page builders included.
Image alt text
Missing alt texts filled from the file name or title. Hand-written ones stay, and one click takes it all back.
robots.txt
Switches for which AI bots may read your site and what search engines should skip. No file to edit.
llms.txt
A short guide to your site for AI assistants, built from your menu and newest posts, with room for your words.
Verification codes
Prove to Google, Bing, Pinterest and Facebook that the site is yours. Paste the code, no theme editing.
Heavy images
Which images weigh over 300 KB and how much they take together. A report only, nothing is compressed.
Speed tweaks
Stop loading the emoji and embed scripts and other extras most sites never use. Each one behind a switch.
HTTPS
Certificate expiry at a glance, an email before it runs out, and every http:// visit sent to https://.
Security headers
HSTS and the basic protective headers, each behind a switch, with a check of what visitors really get.
Hardening
Close the doors only attackers use: XML-RPC, leaked login names, the WordPress version, the file editor.
Comment spam
A hidden field and a timer catch the bots in your comment form. No outside service, nothing deleted.
Cleanup
Old revisions, spam, trash and expired data counted in the database and removed with a click, never on its own.
Maintenance mode
A "back soon" page for visitors while you work, the real site for you. Search engines know it is temporary.

Cookie decline rate
How many visitors decline analytics cookies on your banner, visits Google Analytics never sees. Works with WP Consent API, Complianz, CookieYes and Cookiebot.
