DMValdez Semantic Engine is a schema-first technical SEO plugin, not an all-in-one content suite. If you want structured data, meta tags, and a sitemap done cleanly — without a keyword-research dashboard, an AI writing assistant, or a settings maze — this is built for exactly that.
Every feature ships as clean, valid output: a single JSON-LD block per page (no duplicate or conflicting schema), zero JavaScript on the frontend, and a free tier that’s actually complete — not a teaser for a paywall.
What’s included in the free version
SEO Basics * Custom SEO Title, Meta Description, and Focus Keyword per post and page * Character counters in the editor to keep you within recommended limits * All fields saved directly as post meta — no lock-in
Structured Data (JSON-LD Schema) * WebPage, Article, BlogPosting, AboutPage, ContactPage, and FAQPage schema types * Automatic BreadcrumbList schema on all posts and pages * Organization / Publisher schema linked to your site identity settings * Clean, valid JSON-LD output — no inline microdata, no conflicting markup
[dmvlite_faq] Shortcode
* Render native HTML5 accordion FAQ sections anywhere in your content
* Injects FAQPage JSON-LD automatically for Google Rich Results eligibility
* Attributes: htag (h2/h3/h4/h5/none), open (none/first/all), style (card/minimal/flush)
XML Sitemap
* Generates /sitemap.xml listing your published posts and pages
* Respects per-post noindex settings — excluded posts don’t appear in the sitemap
* Sitemap URL is automatically injected into your robots.txt
* 12-hour transient cache with automatic refresh on publish/update
* [dmvlite_sitemap] shortcode for an HTML sitemap on any page
Open Graph & Twitter Cards * og:title, og:description, og:type, og:url, og:site_name, og:image * Twitter Card (summary_large_image when a social image is set, summary otherwise) * Falls back to Featured Image for og:image when no social image is specified
Visibility Controls * noindex per post — hide specific content from search engines * nofollow per post — block link equity on specific pages * 301 Redirect — set a permanent redirect URL directly on any post or page
Admin Columns * Schema Type and SEO Status columns on Posts and Pages list screens * Quick visual confirmation of which pages have titles and descriptions set
