Our paid plans are better than SEOPress Pro plus SEOPress Insights (in Insights they give ranking info) package. They make you buy both in order for them to work.
And we offer data-driven SEO alongside over 650 features for SEO, something their plugin can’t do, because they don’t use cloud services.
You can see a side by side comparison and hear from people who’ve switched from SEO Press to Squirrly SEO HERE.
But in case you want to keep using SEOpress, you can make Squirrly SEO work in compatibility mode with SEOPress.
Basically, you can use Squirrly SEO to power up WP on top of everything that is already handled by SEOpress.
