The short answer

Which WordPress SEO plugin should I use?

For one site on a budget, a free plugin is enough to start: Rank Math Free is the most generous, Yoast SEO is the most established, and The SEO Framework is the leanest. If you want paid features at the lowest price, SmartCrawl Pro starts at $36 a year and SEOPress PRO at $49. Slim SEO and Squirrly SEO also have free versions. If you run many of your own sites, Rank Math Pro covers unlimited personal sites.

Choose ItNirman SEO when you want every feature in every plan, with no features held back for a higher tier, plus Search Console, GA4 and Bing reporting, daily keyword history, a 40+ check site audit and control over 50+ AI crawlers built into WordPress. It does not have a free version or AI writing tools, and its community is still small.

Each plugin is strong at something. ItNirman SEO's strengths are reporting, the audit and AI-crawler control in one price; its gaps are the lack of a free version, AI writing tools and a large community.

The real differences

How These Plugins Actually Differ

Business model

Yoast, Rank Math, AIOSEO, SEOPress, Squirrly, SmartCrawl and Slim SEO give away a capable free plugin and charge for more. The SEO Framework is free with optional extensions. That suits people who need the basics. ItNirman SEO has no free tier; in exchange, nothing is locked, and Single and Business differ only in the number of sites.

Tier ladders

AIOSEO spreads features over four tiers, with rank tracking and Search Statistics at the top. SEOPress sells rank tracking separately as Insights. Rank Math puts the rank tracker and advanced schema in Pro. In ItNirman SEO, all of it is in every plan.

Where the work happens

Most of these plugins focus on the editor. ItNirman SEO also covers what happens after you publish: Search Console, Google Analytics 4 and Bing data, daily keyword history, a scored site audit, link health and an index-status check, all inside WordPress.

Most of the group now publishes an llms.txt file. ItNirman SEO adds per-company allow or block rules for more than 50 AI crawlers and an AI Reach Tracker that records which crawlers actually read your pages, by name only. Several rivals offer AI writing tools, which ItNirman SEO does not.

Maturity

Yoast has more than 10 million active installs, Rank Math more than 4 million and AIOSEO more than 2 million. ItNirman SEO is newer with a smaller community. If years of tutorials and integrations matter most, that counts for the established plugins.

Switching

Moving Between Plugins Is Not Scary

ItNirman SEO imports from Yoast and Rank Math. Try it on a staging copy first.

  1. 01

    Make a staging copy

    Test there first. Addresses ending in .local or .test never use a licence slot.

  2. 02

    Run the importer

    Titles, descriptions, focus keywords and social overrides come across from Yoast SEO or Rank Math.

  3. 03

    Check a few pages

    Compare titles and schema on key pages, and the sitemap at /sitemap_index.xml.

  4. 04

    Deactivate the old plugin

    A warning shows while two SEO plugins are active. Once you are happy, deactivate the old one.
