Zinn® SEO: a fast WordPress SEO plugin that adds nothing to your pages

No. That is the whole point. It adds 0 scripts, 0 stylesheets and no plugin comment to your visitors' pages, so your site is as fast with it as without it.

Yes. While your other SEO plugin is switched on, Zinn® SEO stays out of its way so nothing is doubled up. Once you are happy, keep just one.

Yes. Your sitemap is prepared in the background and loads instantly. On a test site with a million posts it was ready in 142 seconds using 115.9 MB of memory.

It depends which ones. Block the crawlers that answer questions and you vanish from AI answers that would have linked to you. Block the ones that only train AI models and you lose nothing. Zinn® SEO sets that up in one click.

No. The writing checks in the free plugin all run on your own site. Two optional Pro features reach outside, and only when you use them: one reads competitor pages you name, the other uses the AI service you connect with your own key.

Yes, if you run WordPress 6.4 or newer on PHP 7.4 to 8.5.

Most sites do not. Pro adds unlimited focus phrases, a history of every SEO change, more rich result types, automatic links, a broken link checker, video and news sitemaps and spreadsheet editing, from $49 a year.

Delete the plugin and everything it added is removed. If you would rather keep your SEO details, tick Keep my SEO data if the plugin is deleted under Settings, Data first.

Yes, for free. Export your settings to one file and import it on another site: titles, structured data, sitemaps, robots rules, sharing, breadcrumbs and which features are on all come over, and the site's own address is put in for you. You see every change before anything is applied, and a file with one value that is not allowed is refused whole. Keys and connections never leave the site.

It does the same job inside WordPress, for a fraction of the price: as you write, it scores how well your post covers the words, names, questions and headings of the 10 pages that rank for your phrase, and lists what to add and what you overuse. There is no monthly plan: the plugin is free, and reading the top 10 for a phrase costs $0.05 once, from your Zinn® account balance, then is kept for every post that targets it. It works in 58 languages, in the block editor, the classic editor, Elementor and other page builders.

Yes, for free. In Structured data, Fill with AI, the AI writes an FAQ, how-to steps, product details or an article summary from each page's own text, for every page that has none, a few pages per request. You see the cost first (measured on our own account: about $0.06–$0.16 per 100 pages for FAQs), review every one with its check against schema.org and Google's rules, and undo a whole batch in one click. The FAQ shows on the page under its text, as Google requires. Google stopped showing FAQ rich results in May 2026, but Bing and AI assistants still read FAQ structured data. Pages with an FAQ of their own are left alone and cost nothing.

Yes, with Pro. Site care checks every file against the official copies and your accounts, settings and pages for malware and spam, reads your error logs and explains each error with the fix, and cleans up the database safely. Every change is backed up first, nothing is deleted and everything can be undone in one click. The AI only sees your code with your secrets removed, and a code fix is switched on only after you approve it and it passes a test.

Yes, with Pro: Fix it on autopilot fixes the whole Fix it list in one run, across the whole site or one section. It writes the missing meta descriptions, gives pages that share a title their own, writes alt text, fills in structured data, plans the internal links and runs the one-click fixes. You see what it will change and what it costs first, approve it all or one by one, every change keeps the value it replaced, and a whole run undoes in one click. It can run weekly and e-mail you a summary. Yoast SEO Premium, Rank Math and All in One SEO offer bulk AI titles and descriptions (Rank Math also bulk alt text) from their own post lists; their pages describe no run over the whole issue list and no one-click undo of a run.

Yes, with Pro: Fix every internal link reads every page and fixes, in one run you review first, the links that hop through a redirect or a chain, land on a missing, trashed, unpublished or hidden page, or point at the wrong language. Redirected links go straight to the live page, wrong-language links to the translation, and for a page that is gone the AI proposes the closest page by meaning. Each page changed keeps a revision and the whole run undoes in one click. By their own pages (read 2026-10-16), Link Whisper Premium's error report finds broken links and its link changer swaps one address for another across the site, and All in One SEO pairs its Link Assistant with a separate Broken Link Checker; neither describes fixing links that only go through a redirect or point at the wrong language.

Yes, in Pro. Links, Outbound links lists every site your pages link to with the links, pages, words and link type, checks whether each site is still live, and flags spam or expired domains. Change or remove one link where it is, or every link to a site at once: you review it first, each page keeps a revision, and a whole change undoes in one click.

Yes, with Zinn® SEO Pro. Safe updates tries each plugin, theme and WordPress update on a copy of your site that visitors never see, reads your key pages, forms, checkout and signed-in screens with both versions, and installs it only when nothing breaks. The version before is kept, and if your site breaks after an update it is put back by itself. The AI explains any problem in plain words and can write a small fix for you to approve.
