Changelog
What changed, and when
Pricing in this market changes quarterly and features change monthly. Every material change to our data, our rankings and our corrections is logged here with a date, so you can tell whether this site is maintained rather than taking our word for it.
Full rebuild and re-verification
- Expanded the tool dataset from 7 to 30 products across 8 categories, every price and plan re-read on the vendor's own site.
- Added a ten-capability matrix applied identically to every tool, replacing prose-only feature lists.
- Added 95 head-to-head comparison pages, 30 alternatives pages and 15 use-case buying guides.
- Added 14 free calculators and generators, all client-side, with no signup and no data collection.
- Added a 61-term glossary with DefinedTerm markup and a sourced AI SEO statistics page.
- Published the ranking criteria and their weights on the methodology page, and added an about page naming the publication director.
- Self-hosted the web fonts, consolidated JSON-LD into a single @graph per page, and split the sitemap into an index with section sitemaps.
- Corrected Sorank's pricing: Essential is $99 per site per month and Pro is $249, with a 3-day trial and a published 90-day guarantee.
- Corrected Surfer SEO, Semrush, Ahrefs and Writesonic pricing, all of which had changed since the previous verification.
First publication
- Launched with 7 tool reviews, 3 comparisons and 50 blog articles.
- Published the ownership disclosure: this site is operated by the company behind Sorank.
- Excluded AutoSEO (autoseo.ai) because its domain is parked with no live product.
Frequently asked questions
Why publish a changelog at all?
Because pricing in this category changes quarterly, and a comparison site that silently edits its numbers is asking you to trust it rather than check it. Dated changes let you see whether the site is maintained and what was wrong before.
How often do you re-verify prices?
Fully, at least twice a year across all 30 tools, and individually whenever a vendor tells us something changed or we spot it. Every page carries the date its data was verified.
Do you log corrections as well as updates?
Yes. Corrections are the entries that matter most, so they are named as corrections rather than folded into an 'improvements' line.
Spotted something out of date? Tell us and it will appear here with your correction.
Last verified 2 August 2026. Prices, plans and features on this page were read on each vendor's own site on that date. Vendors change pricing often, so confirm before you buy. Spotted an error? Tell us and we will fix it.
