Why Markzen SEO

Markzen SEO puts every SEO tool you actually need into one well-built plugin — with zero frontend performance impact.

What’s Inside

Twelve tools. One plugin.

Meta management

Custom SEO titles, meta descriptions, canonical URLs, and per-post noindex/nofollow control, with a live Google SERP preview before you publish.

Open Graph & Twitter Cards

Automatic og: and Twitter card tags with per-post overrides, so shared content always looks right — no extra configuration.

XML Sitemaps

Auto-generated sitemaps for posts, pages, categories, and tags, with automatic Google and Bing pings on publish, and full control over what’s included.

Robots.txt

Virtual robots.txt management with no file-system writes, plus detection and alerts for any physical robots.txt that would override your settings.

Broken link checker

Background scan of every internal and external link with HTTP status codes, per-link recheck, and false-positive ignoring. Results persist between scans.

Image alt-text auditor

Background scan that finds images missing descriptive alt text, with a direct edit link to every affected post.

Script detector

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.

Lighthouse / PageSpeed Insights

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.

Focus keyphrase tracking

Assign a keyphrase per post with built-in duplicate detection that flags keyword cannibalization before your own pages compete against each other.

Structured data (Schema)

Automatic JSON-LD for Article, WebSite, and LocalBusiness to help search engines display rich results.

Breadcrumbs

Schema-ready breadcrumbs via shortcode, outputting JSON-LD markup alongside the visible trail.

Dashboard & Site Health

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.

The Difference

Why Markzen SEO

Zero frontend performance impact

No JavaScript and no CSS on public pages; every frontend feature is plain HTML, so your PageSpeed and Core Web Vitals scores are untouched.

Works without an API key

Lighthouse runs on Google’s free PageSpeed Insights API; add an optional free key only if you want higher limits on bulk audits.

Privacy-first

No tracking, no cookies, and no visitor fingerprinting. Output is limited to HTML meta tags and structured data in your page head.

The Process

Getting started

Three steps from install to your first SEO scan.

1

Install the plugin

Install from your WordPress admin (Plugins → Add New → search “Markzen SEO”), or upload the plugin directory.

2

Run your first scan

Activate it, then open SEO → Dashboard to run the first scan and review your SEO status.

3

Configure and publish

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.

FAQ

Frequently asked questions

No. Zero JS and zero CSS on public pages; all frontend output is plain HTML, so PageSpeed and Core Web Vitals are unaffected.
