XypherSEO

Yes. Every feature described on this page is in the free plugin, available to every user, with no account, no credits, no usage limits and no trial period. It is GPL licensed and it stays free. Two paid plugins with a broader feature set are sold separately at xypherseo.com. They are entirely optional and separate. This plugin does not check for a license, does not nag you to upgrade, and does not withhold anything from you.

At xypherseo.com. They are separate downloads and are not part of this plugin.

No. There is nothing to sign up for and nothing to connect. Every check runs on your own server against your own content. The plugin makes no outbound requests and transmits no data anywhere.

Yes. It is a full replacement, not an add-on. It handles titles, meta descriptions, canonicals, robots directives, Open Graph and Twitter Card tags, structured data, XML sitemaps, breadcrumbs, redirects and 404 monitoring. You should not run it alongside another SEO plugin. Two SEO plugins will each write their own meta tags and sitemaps, and search engines will see duplicates. XypherSEO detects this and warns you, but the fix is to pick one and deactivate the other.

If another SEO plugin is active, yes, you will get duplicate structured data. That is true of any two SEO plugins, not just this one. The built-in conflict check tells you when it is happening. If XypherSEO is your only SEO plugin, there is no conflict. Article and BreadcrumbList schema are generated automatically, and anything you add manually in the Schema tab is validated as JSON before it saves, so malformed markup never reaches a live page.

No. All analysis happens in the admin while you are editing, never on the front end. On the front end the plugin outputs meta tags and JSON-LD, which is a handful of lines in the page head. Sitemaps are generated on request, not on every page load.

Open the Schema tab in the XypherSEO panel below the editor, paste valid FAQPage JSON-LD into the FAQ field, and update the post. It is checked as valid JSON when you save and output in the page head. There are separate fields for HowTo and Product schema, and a free-form field for any other type.

At /xypher-sitemap.xml on your site once you enable it. That is a sitemap index that links to separate sitemaps for posts, pages, custom post types, taxonomies and authors. It is styled so it is readable when you open it in a browser. WordPress ships its own core sitemap. XypherSEO replaces it when you turn the XypherSEO sitemap on.

Go to XypherSEO > 404 Monitor to see which URLs visitors are actually hitting. Then go to XypherSEO > Redirects, add a rule with the old URL as the source and the new one as the destination, and pick the status code. Use 301 for a permanent move, which is what you want in almost every case. Each rule tracks how many times it has fired.

Yes. Content analysis reads the rendered content, so word count, keyword count and every content-based check work correctly on pages built with Elementor and similar builders, rather than reporting zero.

It stops the plugin writing anything to the front end: no meta tags, no structured data, no Open Graph tags, no breadcrumbs. The admin screens keep working normally. It exists so you can determine whether a display problem is caused by this plugin without deactivating it and losing your settings. Turn it on, check the page, turn it off.

The 30 checks are grouped by how much they matter and how much work they take. Basics covers the fundamentals every page needs. Intermediate covers title structure, content length and linking. Advanced covers readability and content depth. Pro covers the refinements that separate a good page from a well-optimized one. Clear Basics on every page first, then work down as you have time. All thirty checks are available to every user.

Yes. XypherSEO > Settings has CSV import and export for your settings and your redirect rules, so you can set up one site and replicate it, or keep a backup before making changes.

Yes. Deleting XypherSEO through the Plugins screen removes its options, its post meta and its database tables. Deactivating it leaves everything in place, so you can deactivate safely while troubleshooting.

Yes. Every check is based on published guidance from search engines about on-page quality: clear titles, accurate descriptions, sensible heading structure, readable content, descriptive alt text and valid structured data. There is nothing here that manipulates rankings or that you would need to hide.
