Authoritas vs Siteimprove (2026): which should you pick?

Pick Authoritas if

• Fits if you track rankings across many countries, devices and cities
• Works for one small site that can live on 1,000 rank credits a month

Look elsewhere if

• Pricey if you just need a few hundred keywords tracked, at $129 a month for 1 user
• Tight if you track one keyword in many places, as each place uses another credit
• Skip it if AI answer tracking is the point, since that's a separate product from $119 a month
• Watch out: the Platform API, BigQuery and Looker Studio templates are Enterprise only, at an unpublished price
• Watch out: the free account goes if you don't log in every 30 days, and going past your credits means upgrading

Pick Siteimprove if

• Fits if you need accessibility compliance and SEO in one platform
• Works for universities or government bodies looking after lots of sites

Look elsewhere if

• Not for you if you want a price or a trial before talking to sales
• Too light for SEOs whose work is keyword research or backlinks, as neither is on record
• Skip it if you're a small business, as it's built and sold for large organizations
• Watch out: the free extension checks accessibility only, so the SEO side can't be tried without a demo

Authoritas

• Every rank check uses credits: a new country, device or location for the same keyword costs another credit.
• AI search tracking is a separate product, from $119 a month for 2,000 prompt credits; search-grounded models need an Enterprise plan.
• To go past a plan's monthly credit allowance on the SEO platform you upgrade to the next tier.
• Platform API access, BigQuery and Looker Studio templates are listed as Enterprise features.

Siteimprove

• No prices are published: Siteimprove is sold after a demo, and its site lists no free plan or self-serve trial.
• It is built for enterprises and says it serves more than 5,000 organizations; free checkers and a free site report are the only self-serve options.
• The free browser extension checks accessibility only, in Chrome, Firefox, Edge and Opera.
