The best SEO competitor analysis tools in 2026

Five platforms dominate this, they all have the same core features, and the differences are narrower than their marketing suggests. Prices were read from each vendor's own pricing page on 4 October 2026, on monthly billing unless stated.

What they cost

Ahrefs and Semrush both charge per additional user on top of the plan, which changes the comparison for any team above one person. A three person Semrush team on the entry plan is not $139.

The jobs, and which tool wins each

Keyword gap: what do they rank for that I do not

All of Semrush, Ahrefs and SpyFu do this well. The lists differ because the underlying keyword databases differ, not because one is right.

Practical advice: run it in whichever you have, then filter hard. A raw keyword gap report returns thousands of keywords of which perhaps forty are worth acting on. The filtering is the work, not the export.

Backlinks: who links to them

Ahrefs has the best index and has for years. If backlinks are the centre of your job, this is the one.

Semrush is close enough for most purposes. Moz and Majestic remain credible and cheaper, with Moz from $49 a month and Majestic Lite at $49.99, both billed monthly.

Paid search history

SpyFu goes deepest for the money. Semrush covers it in a separate Advertising toolkit, from $99 a month billed annually.

Traffic estimates and market share

Similarweb is the standard among website traffic checkers, largely because it uses panel and clickstream data rather than inferring from rankings, which makes it better for sites that get traffic from somewhere other than search.

Its self-serve plans start at $199 a month, or $125 billed annually, for one user, three months of history and a worldwide view; the prices sit in the pricing page's data rather than on screen. Anything fuller means a sales process and a significant annual number.

Local and multi location

Semrush has the more developed local toolset.

What none of them do

They are research platforms. You go to them with a question.

None of them will tell you on Monday that a competitor published eleven pages last week, started running ads on your brand name, and cut the entry price on their pricing page. That is monitoring, and it is a different product shape.

This is the gap our own tool sits in. Figo runs the search data weekly rather than on demand, at $49 a month for three competitors and $99 for eight, and reports what changed alongside ads, content, social and reviews, in a written briefing.

It is not as deep as Ahrefs or Semrush on search, and we would not claim otherwise. There is no backlink index, no keyword research workflow, no site audit. If your job is SEO all day, buy a real SEO platform. If your job is knowing what competitors are doing, the depth you need is much shallower than the depth they sell.

What you can do for nothing

Google Search Console. Your own queries, your own positions, your own losses. Free, and underused by nearly everybody who pays for a platform.

The actual SERP, in incognito. Who ranks, what they titled it, which page type won. It is also where a proper SEO competitor analysis starts. Ten minutes on your five main terms teaches you more than most reports.

Their sitemap.xml. Every page they have, usually with dates. Diff it monthly to see exactly what they publish.

Google Trends. Relative brand interest over time.

That is not a substitute for a keyword database. It is enough to know whether you have a problem worth buying a database to solve.

Choosing

• Backlinks are central: Ahrefs.
• You want the widest toolset and do paid search too: Semrush.
• Paid search history on a budget: SpyFu.
• Market share and non search traffic: Similarweb, and for more than its one user self-serve plans, prepare for a sales call.
• You want it watched weekly rather than researched occasionally: a monitor, ours or otherwise.
• You have no budget: Search Console and the SERP, honestly.
