THiS SEO is a focused WordPress SEO plugin built for SEO professionals and agencies who need to work fast. No score widgets, no banner ads, no tracking. Just the workflow tools you actually need.
Used by SEO professionals who already use dedicated analysis tools and AI — THiS SEO handles the technical execution inside WordPress without getting in the way.
<h4>Core Features (Free)</h4>
Meta Editor 
Edit SEO titles and meta descriptions for all your pages and posts in one clean overview. See character counts, spot missing meta, and save everything in seconds without opening each post individually.
Schema Library 
Build and manage JSON-LD schema templates with dynamic variables like <code>{{post_title}}</code>, <code>{{post_url}}</code>, and <code>{{featured_image}}</code>. Assign templates globally or to specific pages. Supports Article, Organization, WebApplication, SoftwareApplication, AboutPage and more.
Redirects 
Create and manage 301, 302 and 307 redirects directly from the WordPress admin. Import and export via CSV. Fast, lightweight redirect handler with no database overhead on uncached requests.
404 Log 
Automatically log all 404 errors on your site. See which URLs are returning not found, how often, and where users came from. Turn common 404s into redirects in one click.
Broken Link Scanner 
Scan any page for broken internal and external links directly from the admin. See HTTP status codes, identify dead links, and fix them before they hurt your rankings.
Sitemap 
Auto-generated XML sitemap at /sitemap.xml. Automatically pings Google and Bing on save. Integrates with robots.txt automatically.
SEO Lock™ – PIN Protection (Free) 
Protect your most sensitive SEO settings with a 4-digit PIN. Uses bcrypt hashing, rate limiting (3 attempts, 15-minute lockout), and session management. Prevents accidental or unauthorized changes to redirects, schema, and robots.txt.
