Schema Engine

@graph architecture that Google loves

Most plugins output disconnected schema blocks. DMValdez Pro merges everything into a single unified @graph array where every entity is mathematically linked — zero duplicate errors, zero entity clashes.

  • 15+ schema types: LocalBusiness, FAQPage, Article, NewsArticle, Event, Product, ProfilePage, and more
  • Automatic @id linking between WebPage, Organization, and content entities
  • Smart JSON sanitizer strips invisible characters and repairs malformed quotes
  • Advanced JSON-LD injection panel for custom schemas on any post type
  • Validated against Google Rich Results Test — 0 errors, 0 warnings

  • Virtual /llms.txt endpoint — no physical file, no server config needed
  • Auto-populates with business name, services, target audience, and key URLs

Sitemap Engine

A sitemap that's
actually beautiful

DMValdez Pro generates a Google-preferred split sitemap index with separate child sitemaps per content type. A custom XSL stylesheet transforms the raw XML into a branded, navigable visual design when opened in a browser.

  • Split index: sitemap.xml → sitemap-pages.xml + sitemap-posts.xml
  • Optional: category, tag, custom taxonomy, and author archive sitemaps
  • Custom XSL stylesheet — dark theme, priority pills, lastmod, animated header
  • Auto-injects Sitemap: directive into your robots.txt
  • 24-hour transient cache with automatic bust on publish

FAQ

Frequently asked questions

Do I need the free plugin too?
Yes. DMValdez Semantic Engine Pro is an add-on — it requires the free DMValdez Semantic Engine plugin (WordPress.org) to be installed and active. The free plugin covers the essentials: SEO meta fields, Article/WebPage schema, the full [dmvlite_faq] shortcode, a flat XML sitemap, and noindex controls. Pro adds 15+ schema types, enterprise @graph JSON-LD architecture, Google Places API, LLMs.txt AI optimization, the professional split sitemap with XSL design, the SEO Data Bridge (import/export from Yoast/RankMath/SEOPress), Bulk Meta Editor, and OTA updates.
Does it work with Elementor?
Yes. Pro includes deep Elementor integration — advanced schema controls and a live content density analyzer operate natively inside the Elementor editor, alongside the free plugin's own SEO tab. The FAQ shortcode and HTML sitemap shortcode render perfectly in Elementor pages.
Can I migrate my data from Yoast or Rank Math?
Yes. The Pro SEO Data Bridge imports SEO titles, meta descriptions, and focus keywords from Yoast, Rank Math, SEOPress, and Link Whisper in one click. You can also export DMValdez data back to any of those plugins. A "Force Import" option overwrites any existing data if needed.
How does OTA (Over-The-Air) updating work?
Pro connects securely to a private licensing server. Updates appear directly in your WordPress dashboard Plugins screen — exactly like any repository plugin. No manual zip uploads. The One-Time Purchase license includes OTA updates for 12 months from purchase date.
Does this handle off-site SEO too, like backlinks?
No. DMValdez Semantic Engine Pro performs on-site (on-page) SEO and AEO optimization only — titles, meta tags, schema markup, internal linking suggestions, sitemaps, and llms.txt. It does not control or guarantee off-site/off-page ranking factors such as backlinks, citations, or directory listings; it can audit and surface suggestions for those, not execute them. See the full disclaimer.
Will this conflict with other SEO plugins?
DMValdez Semantic Engine (free + Pro) is designed to be the only SEO plugin on a site. Running multiple SEO plugins simultaneously creates duplicate meta tags and conflicting schema output. If you're migrating from Yoast or Rank Math, use the SEO Data Bridge to transfer your data, then deactivate the old plugin.
What is the LLMs.txt engine?
It generates a virtual /llms.txt endpoint on your WordPress site without creating any physical file. This Markdown document provides AI language models (ChatGPT, Claude, Perplexity) with curated business context, services, target audience, and key URLs — increasing the likelihood those AI assistants cite your site accurately in responses.
How is this different from Yoast or Rank Math?
DMValdez Semantic Engine Pro is built for developers and site owners who need enterprise control without plugin bloat. Key differences: enterprise @graph schema linking (not just individual blocks), Google Places API for automatic local business data, LLMs.txt AI optimization, a visually-designed XML sitemap with XSL, and an active OTA update pipeline. It does not include content writing tools or keyword research widgets — it's a precision technical SEO engine.
Scope & Disclaimer

On-site SEO & AEO only

DMValdez Semantic Engine Pro (and the free DMValdez Semantic Engine plugin it requires) performs on-site / on-page search and answer-engine optimization — SEO titles, meta descriptions, structured data (JSON-LD schema), internal linking suggestions, XML sitemaps, and the llms.txt AI-discovery endpoint. All of that lives inside your WordPress install and is fully under your control.

It does not control or guarantee off-site / off-page ranking factors — things like backlinks, citations, directory listings, review signals, or social proof, which are determined by activity outside your website. The plugin's smart interlinking and keyword tools can audit your site and surface suggestions relevant to off-site strategy (e.g. orphaned-content flags, missing local citations to pursue), but it cannot create backlinks, submit citations, or otherwise act on the open web on your behalf.

Search rankings depend on many factors outside any plugin's control, including competition, algorithm changes, and off-site signals. No SEO tool — this one included — can guarantee specific rankings or traffic outcomes.

The story behind DMValdez Semantic Engine Pro

DMValdez Semantic Engine Pro grew out of years of hands-on client SEO work — built out of frustration with bloated SEO plugins that added overhead without delivering enterprise-grade schema output or AI-readiness.

What started as a set of private WordPress customizations evolved into a full plugin architecture: @graph schema linking, Google Places API automation, LLMs.txt optimization, and a professional sitemap engine — now available as an independent product.

Pro is actively maintained with an OTA update pipeline. The free plugin on WordPress.org brings the core toolset to the broader community, while Pro keeps pace with AI search evolution as an add-on for developers and site owners who need more.
