The bottom line
Feature-rich SEO suite, but pricing structure and trial billing complaints make switching worth a serious look.
Semrush covers more ground than most SEO suites: keyword research against a 29 billion keyword database, backlink checks against a 43 trillion link index, rank tracking, technical audits, and newer AI visibility tracking for ChatGPT and Gemini mentions. The entry SEO plan runs $117.33/mo billed annually ($139 month-to-month) and caps out at 5 sites and 500 keywords tracked daily, per the pricing page. Climbing to Starter, Pro+, or the custom Advanced and Enterprise tiers buys more keyword slots, prompt tracking, and API access, but add-ons like extra users ($45/mo) and report credits ($10-$20/mo) stack fast.
Reddit sentiment is rough. Multiple threads on r/SEO are literally titled around finding Semrush alternatives, with commenters citing inaccurate data for small and midsize sites, a pricing structure that one user called "sectioned off" across features, and a billing dispute thread where users report being charged before a 7-day trial ended with no refund. Several commenters now point to Ahrefs, DataForSEO paired with Claude, or free GSC/GA4 setups instead. The recurring theme since Adobe's acquisition: people who've used Semrush for years are actively pricing out the door.

01What Semrush actually does
Semrush is a broad SEO and AI-search visibility suite built around six core jobs: keyword research, backlink analysis, rank tracking, content optimization, technical site audits, and AI visibility tracking. The pricing page says the keyword database covers 29 billion keywords and the backlink index holds 43 trillion links, which Semrush calls the largest available.
The newer piece is AI visibility tracking, which monitors how often a brand gets mentioned inside ChatGPT, Gemini and other LLM answers, plus an MCP connector that feeds Semrush data directly into AI assistants. The site's by-size and by-role menus pitch this at everyone from solo marketers to enterprise teams and agencies, with separate plan tiers built around that range.
02Where Semrush is strong
Semrush's biggest selling point is breadth. Few tools try to cover this much ground in one subscription:
- Keyword research against a 29 billion-keyword database, per the pricing page
- Backlink analysis against a 43 trillion-link index, which Semrush markets as the largest backlink database around
- Position Tracking and technical Site Audit bundled into the entry SEO plan
- AI search performance and sentiment monitoring included even on the cheapest paid tier
- Real-time content scoring and topic discovery for content teams
- An MCP connector that pipes Semrush data straight into AI assistants, a feature most legacy SEO suites don't have yet
The free plan is a genuine way to poke around before paying: one demo project and 10 reports a day across the toolset, which is thin but enough to test the interface. For agencies that want one login instead of five separate tools for keywords, backlinks, rankings, and AI tracking, that consolidation is the real argument for paying Semrush's prices instead of stitching together cheaper point solutions.
03Where it falls short
The pricing structure gates core AI visibility features hard. Starter tracks only 50 prompts a day across 1 domain; Pro+ bumps that to 100 prompts; unlimited prompt tracking only shows up on the custom Advanced and Enterprise tiers, according to the pricing page. Keyword tracking caps follow the same pattern: 500 keywords daily on SEO and Starter, 1,500 on Pro+, 5,000+ only on Advanced.
Extra seats cost $45/month per the add-ons list, and reporting add-ons (Base Report $10/mo, Pro Report $20/mo) sit outside the base plans entirely.
Reddit complaints cluster around two things: billing and data accuracy. One widely upvoted thread titled "Semrush is a SCAM" describes trial charges landing before the 7-day window closes and refunds being refused, with the top comment simply noting Adobe now owns the company. Separate threads comparing alternatives include commenters saying "Semrush data for small/midsize website is not great," and others reporting SERP and traffic numbers that don't match their own Search Console data.
04Semrush pricing: what you'll actually pay
Semrush's pricing page shows a Free plan (10 reports a day, 1 demo project) sitting next to a $139/month SEO plan — or $117.33/month if you pay annually. That annual discount pattern repeats across every paid tier, so the "sticker price" on the homepage and the price you're billed can differ by roughly 15-17%.
The real jump isn't Free to SEO, it's SEO to Starter. For $60 more a month ($199 vs $139), Starter adds MCP access, 50 tracked AI prompts and 300 AI visibility reports a day — features the SEO plan doesn't get despite tracking the same 500 keywords and 5 sites.
Pro+ at $299/month ($248.17 annual) triples site and keyword limits but only doubles AI prompt tracking to 100. Above that, Advanced and Enterprise are quote-only.
Add-ons stack fast: extra users start at $45/month, a Pro Report add-on is $20/month, and an Agency Partners listing runs $90/month.
05Switching to (or from) Semrush
Semrush doesn't publish a one-click export-everything tool on its pricing or feature pages, so migrating a project's keyword lists, tracked rankings and backlink reports typically means exporting tool-by-tool (CSV from Position Tracking, CSV from backlink audits, and so on) rather than a single data dump.
The free trial is the biggest switching risk worth flagging: the plan structure moves from a 10-report-a-day Free tier straight into paid billing once a trial converts, and the "Not for" list in Semrush's own positioning calls out people "wary of trial-to-paid billing surprises." Read the cancellation terms before starting a trial.
Lock-in is moderate. Keyword tracking history and AI visibility trend data reset if you switch tools, since competitors don't import Semrush's historical rank data. Teams tend to leave when keyword or site caps (500 keywords, 5 sites on SEO and Starter) get outgrown faster than budget allows, pushing them toward the $299 Pro+ tier or a custom Advanced quote.
From the threadsWhat users say
Reddit comments are mostly critical of Semrush, especially its price, perceived data accuracy, and pricing structure. Some users say its estimates are best used for comparisons rather than treated as exact figures, while others question whether an all-in-one suite is worth paying for their needs.
the pricing is hard to justify
Semrush data for small/midsize website is not great
It's gotten a lot worse recently. Everything is sectioned off with separate pricing for different festures
They make you sign up for a 7 day trial and charge you before the actual 7 DAYS are over
Questions people ask
Is Semrush worth the price?
It depends on whether you need its broader SEO and AI visibility tools. The pricing page lists the SEO plan at $139 per month, or $117.33 per month when billed annually, with five websites and 500 daily tracked keywords. Reddit users say the cost is hard to justify, particularly when they mainly need reporting on their own site.
Does Semrush have a free plan?
Yes. The pricing page lists a free plan with one demo project, 10 reports per day across vital tools, and AI Visibility features. A free trial is also available, but the pricing information does not specify its length. Check the current trial terms before signing up, since one Reddit post alleges an early charge during a seven-day trial.
Is Semrush good for keyword research?
Semrush offers keyword research, and its homepage says its database covers 29 billion keywords. The SEO plan includes basic keyword research and competitor analysis, plus 500 keywords tracked daily. Reddit users raise concerns about Semrush data accuracy, so treat its numbers as estimates for comparison rather than exact measurements.
What does Semrush include beyond keyword research?
The platform lists backlink analysis, rank tracking, content optimization, technical site audits, local SEO, advertising tools, and AI visibility tracking. The SEO plan includes Position Tracking and Site Audit. Higher plans add features such as historical SEO data, content optimization, and more daily tracked keywords or AI prompts.
What should I know about Semrush pricing and trial billing?
The pricing page lists the SEO plan at $139 month to month or $117.33 per month billed annually; the trial length is not published on the vendor's site. One Reddit poster says they were charged before a seven-day trial ended and did not receive a refund. That is an individual report, so confirm the current billing and cancellation terms before subscribing.
