Semrush is the default answer to "what SEO tool should I use" for a reason — it does keyword research, site audits, backlink analysis and competitor tracking in one place. That breadth is also the problem: you pay for the whole suite even if you only ever open two of its modules. And Semrush was built for a world where Google was the only place people searched — it's now racing to catch up on a second front: whether ChatGPT, Perplexity and Gemini mention your brand at all, which classic rank tracking doesn't measure. Below are real alternatives for both cases, pulled from live catalog listings.
The short version
If you want a cheaper, more focused classic SEO tool: Wope for competitor keyword-gap research, FrogDR for tracking Domain Rating over time, SEO Flight Deck for straightforward rank tracking, or Emalak if you want a free toolbox and don't need anything fancy. If what you actually need is visibility inside AI answers rather than Google's ten blue links, that's a newer, separate category: SEORCE, VisibilityRadar, Findable and Atyla all specialize in exactly that.
Classic SEO, unbundled from the suite
Wope does one thing well: it shows you exactly which keywords a competitor ranks for that you don't, so you can go after the same traffic instead of guessing at keyword lists. Pricing runs $27/month (Basic, 500 credits) up to $275/month (Elite, 5,000 credits), with a 14-day free trial and no card required. It's aimed at SEO agencies, growing startups and marketing teams doing competitive research — basically the single Semrush feature most people actually use, without the rest of the suite.
FrogDR tracks a site's Domain Rating over time, with change alerts and backlink analysis, for SEO pros and small site owners who want to watch their authority trend rather than run a full audit suite. It has a genuinely free tier for basic DR tracking, with Advanced Monitoring at $5/month adding backlink analysis and unlimited DR updates — a fraction of Semrush's cost if authority tracking is all you need.
SEO Flight Deck is a straightforward Google keyword rank tracker with AI-assisted keyword grouping and daily automated email reports, built for solo consultants and small agencies who don't need — and don't want to pay for — a full suite. Its exact pricing tiers weren't independently verifiable at review time (only third-party aggregator data was available), so confirm current pricing directly before committing, but it offers a 7-day free trial.
Emalak takes the opposite approach entirely: a free toolbox of 20+ SEO and content utilities — backlink checker, keyword analyzer, privacy policy generator and more — aimed at bloggers and webmasters who don't want to pay for a dozen separate point tools. No account, no hidden fees. It won't replace Semrush's depth, but for a solo blogger it may replace the need for Semrush at all.
The category Semrush doesn't fully cover yet: AI answer visibility
Classic SEO tools measure where you rank on Google. A newer category measures something Semrush is only starting to add: whether ChatGPT, Perplexity, Claude and Gemini actually mention your brand when someone asks a relevant question. If AI-assisted search is sending you meaningfully less (or more) traffic than a year ago, this is the gap these tools are built to close.
SEORCE tracks whether your brand shows up across ChatGPT, Gemini and Perplexity, not just Google rankings, and tries to auto-fix what's wrong. It has a genuinely usable free tier (10 AI platforms, 10 prompts/month, 20 tracked keywords), scaling from $49/month (Lite) to $999/month (Enterprise), with a 7-day trial on every paid plan — the most generous entry point of the AI-visibility tools here.
VisibilityRadar checks whether ChatGPT, Claude, Gemini and other models mention your brand when someone asks for a recommendation — explicitly positioned as "the new version of do I rank on Google." Pro is $49/month at launch pricing (listed as 50% off $99), with an Agency tier at $599/month for unlimited analyses. The free tier is limited to one analysis across two AI models, mostly useful for a single gut-check rather than ongoing monitoring.
Findable monitors brand visibility in AI answer engines and scores your content against E-E-A-T criteria, with competitor tracking built in — its marketing cites enterprise users like ByteDance and Klarna, though that's the vendor's own claim. Free covers basic audits and content generation; Pro is 99 EUR/month (83 EUR/month billed annually) for ChatGPT/Google/Meta monitoring; Enterprise adds Claude/Perplexity/Grok monitoring plus a dedicated AEO expert.
Atyla, built in France, tracks how often ChatGPT, Perplexity, Claude, Gemini, Grok, Mistral and DeepSeek cite your brand with competitor benchmarking, and has the lowest entry price of this group at 19 EUR/month (Essential, 2 AI models, 100 pages/month), scaling to 149 EUR/month (Growth, 7 models). It's the most budget-friendly way to dip a toe into AI-visibility tracking before committing to a pricier tool.

Conclusion
If you're paying for Semrush and only using one or two of its modules, any of the four classic-SEO tools above will likely cost less and do that one job just as well. But if your real question is newer than "where do I rank on Google" — if you're worried about whether AI assistants recommend you at all — that's a different category Semrush is still catching up to, and the AI-visibility tools here are purpose-built for it. Most offer a free tier or trial, so the cheapest way to decide is to run your own brand through two or three of them before picking one to pay for.
