At the time of writing (September 2026), Semrush's SEO plan is $139/mo; Similarweb's self-serve plans start at $125/mo billed yearly ($199 monthly) for competitive intelligence, and $333/mo yearly with SEO and AEO.

Where LaunchRanked fits

Disclosure: LaunchRanked is our product. Where we list it, we say so, and we place it under the use case it fits rather than at the top by default. Everything else here is from the vendors’ own sites or our research, and we say where they’re better.

LaunchRanked isn't an SEO suite. We don't have a keyword database, a backlink index or a rank tracker, and we're not a substitute for either tool here. Neither estimates your own site better than Search Console does.

If what you actually want is content published and existing pages fixed, Autopilot ($49/mo, founding price, early access) publishes 30 articles a month and rewrites titles and snippets on pages ranking on page 1–2 of Search Console. Done-for-you (from $999/mo) runs the whole playbook for you.

Frequently asked questions

Is Similarweb an SEO tool?

Partly. Its higher self-serve plans include keyword research, rank tracking, site audit and backlinks, but its core is traffic and market intelligence.

Which is cheaper?

Similarweb's entry plan ($125/mo yearly) is cheaper, but doesn't include SEO tools. With SEO, it's $333/mo yearly, against $139/mo for Semrush's SEO plan, at the time of writing (September 2026).

Are competitor traffic numbers accurate?

They're modelled estimates on both. Use them to compare trends, not as exact figures.
