Every SEO tool you actually need in one well-built plugin — meta tags, sitemaps, broken-link and image audits, and Lighthouse scores. No bloat, no noise, and zero frontend performance impact.
Free plugin on WordPress.org · Pro version with more features coming soon
One screen shows meta coverage, broken links, missing alt text, and Lighthouse scores across your whole site.
No JavaScript or CSS shipped to your visitors — every frontend feature is plain HTML.
Markzen SEO puts every SEO tool you actually need into one well-built plugin — with zero frontend performance impact.
Custom SEO titles, meta descriptions, canonical URLs, and per-post noindex/nofollow control, with a live Google SERP preview before you publish.
Automatic og: and Twitter card tags with per-post overrides, so shared content always looks right — no extra configuration.
Auto-generated sitemaps for posts, pages, categories, and tags, with automatic Google and Bing pings on publish, and full control over what’s included.
Virtual robots.txt management with no file-system writes, plus detection and alerts for any physical robots.txt that would override your settings.
Background scan of every internal and external link with HTTP status codes, per-link recheck, and false-positive ignoring. Results persist between scans.
Background scan that finds images missing descriptive alt text, with a direct edit link to every affected post.
On-demand inventory of every first- and third-party JavaScript file loading on any page, so you know exactly what’s running and where it’s from.
On-demand audits via Google’s free PSI API (no key required), a bulk queue for up to 20 posts, and a per-post SEO score badge in the post list.
Assign a keyphrase per post with built-in duplicate detection that flags keyword cannibalization before your own pages compete against each other.
Automatic JSON-LD for Article, WebSite, and LocalBusiness to help search engines display rich results.
Schema-ready breadcrumbs via shortcode, outputting JSON-LD markup alongside the visible trail.
A single-screen dashboard (meta coverage, broken links, missing alt text, Lighthouse scores) plus a six-check Site Health screen with pass/fail status and direct action links.
No JavaScript and no CSS on public pages; every frontend feature is plain HTML, so your PageSpeed and Core Web Vitals scores are untouched.
Lighthouse runs on Google’s free PageSpeed Insights API; add an optional free key only if you want higher limits on bulk audits.
No tracking, no cookies, and no visitor fingerprinting. Output is limited to HTML meta tags and structured data in your page head.
Three steps from install to your first SEO scan.
Install from your WordPress admin (Plugins → Add New → search “Markzen SEO”), or upload the plugin directory.
Activate it, then open SEO → Dashboard to run the first scan and review your SEO status.
Configure sitemaps, Open Graph, and schema in SEO → Settings, then add a focus keyphrase and meta description to your posts.
Designed to be the only active SEO plugin — deactivate others (e.g. Yoast, Rank Math) first to avoid duplicate meta tags and sitemaps.
No. Zero JS and zero CSS on public pages; all frontend output is plain HTML, so PageSpeed and Core Web Vitals are unaffected.
