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. For AI search, Autopilot tracks 25 prompts across ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews and Google AI Mode every week for one site: the same prompt count as Semrush's entry AI plan, checked less often, and well below Similarweb's 150.

If what you actually want is content published and existing pages fixed, Autopilot ($49/mo, founding price) 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

Which is better for AEO, Semrush or Similarweb?

It depends on what sits next to the AI tracking. Semrush is the better fit if you also need keyword research, daily rank tracking and site audits: its AI Visibility plan is $99/mo per domain for 25 prompts, and SEO + AI Search plans track 50 to 200 prompts from $165.17/mo billed annually ($199 monthly). Similarweb is the better fit if you need competitor and market traffic as well: AEO Intelligence is $99/mo billed annually for 150 prompts, plus referral traffic from AI chatbots.

How many AI prompts can each track?

Semrush: 25 a day on the AI Visibility plan, and 50, 100 or 200 a day on Starter, Pro+ and Advanced (its SEO plan tracks none). Similarweb: 150 on its AEO plans. Semrush's Position Tracking also monitors daily visibility for prompts in ChatGPT and Google AI Mode.

Do both track Google AI Overviews?

Semrush's AI Visibility Toolkit covers Google AI Overviews and AI Mode along with ChatGPT, Gemini, Perplexity and SearchGPT. Similarweb's AI Brand Visibility tool tracks prompts in ChatGPT, Google AI Mode, Gemini and Perplexity. It handles Google AI Overviews separately: its Rank Tracker flags the keywords that trigger an AI Overview, on plans that include its SEO tools. That's detection by keyword, not prompt-by-prompt brand tracking. Platform lists change, so check each vendor's current list before you buy.

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. Semrush starts from SEO.

Which is cheaper?

For AEO alone they match at $99/mo on annual billing (Similarweb is $129 if you pay monthly; Semrush's AI Visibility page shows $99 either way), with Similarweb including 150 prompts to Semrush's 25. For competitor traffic, Similarweb's Competitive Intelligence ($125/mo billed annually) is below Semrush's Traffic & Market Pro ($289/mo billed annually). With SEO tools, Semrush's SEO plan ($117.33/mo billed annually, $139 monthly) is well below Similarweb's SEO and AEO plan ($333/mo billed annually, $399 monthly). Plans change, so check both pricing pages.

Are competitor traffic numbers accurate?

They're modelled estimates on both, built from different data. Use them to compare sites and trends, not as exact figures, and trust Search Console and your analytics for your own site.
