WPSSO Core

Which one is for you
Pick Rank Math if
- Fits if your site runs on WordPress and you want SEO settings in the editor
- Works for someone with several sites of their own, since PRO covers unlimited owned sites
Look elsewhere if
- Skip it if your site isn't on self-hosted WordPress or WordPress.com's Business plan, as it runs nowhere else
- Not for you if you need keyword, backlink or competitor research, which it doesn't do
- Tight if you build sites for clients, as PRO excludes them and Business is €27.99 a month at renewal
- Watch out: prices are in euros before VAT, billed yearly only, with a lower first year, and the 30-day refund skips renewals
- Pricey if you want AI writing, a separate Rank Math AI subscription from €6.99 a month billed yearly
Pick WPSSO Core if
- Fits if you run WooCommerce and want each product variation in your markup
- Works for sites adding schema on top of an SEO plugin they already use
Look elsewhere if
- Too light for your whole SEO setup, as there are no redirects or content checks
- Watch out: Premium is licensed per site address, so a staging site needs its own licence beyond one free dev subdomain
- Tight if you stay free, as YouTube, Vimeo, review-app and short-link data need Premium
- Watch out: licences can't be transferred, and the refund window is 30 days
- Skip it if your site isn't on WordPress 6.0 or newer, as it runs nowhere else
How we grade them
| 3.0GPARank MathVery good | 3.0GPAWPSSO CoreVery good | |
|---|---|---|
| Value for money | AGraded against its alternatives. PRO is €8.99 a month at renewal (€7.99 in the first year), billed yearly before VAT, for unlimited sites you own and 500 tracked keywords. That's under 60% of this category's cheaper quarter, even after converting from euros. | APremium is $49 once for one site, with updates and support for the life of that site. That's less than a year of this category's middle price. Bigger licences fall to $17 a site at 25 sites. |
| Free plan and trial | AThe free plugin from WordPress.org does the core job with no cap a normal site will reach: on-page checks, 16+ schema types, sitemaps, redirects, a 404 monitor and Search Console data every 7 days. | AThe Standard edition on WordPress.org has no caps: schema markup, social tags, WooCommerce product markup and free add-ons for feeds, FAQ pages, breadcrumbs and sitemaps. Premium adds data from YouTube, review apps and link shorteners. |
| Features | COn-page scores against 30+ tests, schema, sitemaps, redirects and rank tracking fed by Search Console. It does its job fully, but that job is on-page SEO for WordPress, with no keyword research, backlinks or competitor data. | CSchema for 500+ types, Open Graph, X Cards and Pinterest tags, every WooCommerce variation as its own offer, and add-ons for merchant feeds and sitemaps. It does markup fully, but that's a smaller job: no redirects or content checks on record. |
| Ease of use | CNo rating on record. Inside WordPress it feels familiar, but you need a self-hosted WordPress site or WordPress.com's Business plan first, then the setup and the Google connections. | CNo rating on record. It needs WordPress 6.0 and PHP 7.4.33 or newer, and the extras come as separate add-ons to install and set up. |
| Platforms and integrations | BRuns inside WordPress in the browser and connects to Search Console, Analytics, Google Trends, WooCommerce, Elementor, Divi, WP Rocket and WPML. Nothing for sites that aren't on WordPress. | BWeb only, inside WordPress.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
