Semrush Alternatives in 2026: 9 Free and Paid Options

The measured truth about your own pages, free, and the foundation under everything else.

Best for: Every site owner, regardless of what else they buy

Semrush estimates your traffic and positions from its own index. Search Console reports what Google actually recorded. Where they disagree, Search Console is right, and that makes it the better input for improving pages you already have.

Almost all the value sits in one report. Performance, filtered to the last three months, sorted by impressions, shows you two things immediately: pages that rank but get no clicks (a snippet problem, fixable in minutes) and queries at positions 8 to 20 (a content or linking problem, worth real effort).

Its limits are worth knowing precisely rather than vaguely: 16 months of history, 1,000 rows exportable from the interface, 50,000 a day through the Search Analytics API, and low-volume queries stripped out of the report entirely. That last one surprises people — the query list is incomplete by design, not by accident.

Verdict: Connect it whatever else you decide. Every paid tool here is approximating data this one measures.

A genuinely useful free tier from Semrush’s biggest competitor — 1,000 backlinks and a full site audit, free.

Best for: Anyone who wants backlink data without paying

The most useful free Semrush alternative is made by Ahrefs. Ahrefs Webmaster Tools, now called Ahrefs Free, gives verified site owners Site Audit with 5,000 crawl credits per project per month, plus 1,000 backlinks and 1,000 organic keywords visible at a time — all from the same link index behind the paid product. Permanent, no card.

Set that against Semrush’s free account — 10 rows, no export — and the comparison is not close. If you are evaluating "free Semrush" against "free Ahrefs", free Ahrefs wins decisively for owned-site work.

The wall is competitor research, and it is absolute. You cannot point Site Explorer at a domain you do not control, at any row count. That restriction is the commercial basis of the paid product.

Verdict: Run this before paying anyone. For owned-site work it covers a surprising amount of what a $139 plan is used for.

Reads your Search Console data, drafts the specific WordPress fix, and ships it once you approve.

Best for: WordPress owners whose backlog is fixes, not findings

Full disclosure: we build RankHive. It is third here, behind two free tools, because that is where it honestly belongs on a page about replacing Semrush — most people reading this should try the free stack first.

RankHive is not a research platform and does not compete with Semrush on data. It reads Google Search Console and your live WordPress site weekly, ranks opportunities by likely impact, and drafts the actual change — a rewritten title, a meta description, schema, an internal link, a content section — with the evidence attached. Nothing ships until you approve it, every change has a log entry, and most can be reverted.

It exists for a specific failure: research that never becomes work. People export Semrush findings into a spreadsheet and the spreadsheet grows. If that describes you, switching to a cheaper research tool produces the same spreadsheet for less money, which is not a fix.

Two honest limits. WordPress only, and it works from your Search Console data — a brand-new site with no impressions gives it little to work with.

Verdict: Right when the bottleneck is shipping. Wrong if you need research breadth — that is what Semrush is for.

The cheapest credible paid swap — about a sixth of Semrush on annual billing, if you can live with daily caps.

Best for: Bloggers and lean content teams

Mangools Entry is $19.90 a month billed annually against Semrush’s $117.33 on annual billing — the largest saving available here by a wide margin. That buys 25 KWFinder lookups a day, 50 tracked keywords, 25,000 LinkMiner backlink rows a month, 25 SERPChecker lookups a day and 10 SiteProfiler lookups a day.

The daily caps are the whole trade-off. Twenty-five keyword lookups is comfortable for a blogger planning next month and nowhere near enough for agency research. Semrush allocates monthly, which absorbs a heavy day; Mangools resets every 24 hours whether you used the allowance or not.

Where Mangools genuinely beats Semrush is time-to-decision. KWFinder puts volume, difficulty and the live SERP in one view. Semrush can answer more questions; Mangools answers the common one faster, which matters more than it sounds if you are the person who also has to write the article.

One caveat: the $19.90 Entry figure needs an annual commitment. Billed monthly, Entry is $30 a month, according to the pricing data Mangools publishes on its KWFinder page.

Verdict: Take it if you used Semrush for keyword research and the $139 stopped making sense.

The closest like-for-like swap, $10 cheaper, with a trial that needs no card.

Best for: Agencies and in-house teams producing client reports

SE Ranking Core is $129 a month against Semrush’s $139, falling to $103.20 on annual billing — a verified 20% discount. It also shares the highest G2 score on this page, 4.7, with Mangools.

It is the closest thing to a like-for-like swap. Rank tracking, site audits, competitor monitoring, keyword research and white-label client reporting are all core rather than bolted on. For anyone who has to hand a client something readable every month, that reporting module is the whole argument.

The 14-day trial requires no card and includes 10 projects, 750 tracked keywords a day and AI competitive research on three domains — enough to test it against real client work rather than poke at a demo. Semrush gives 7 days and asks for a card.

The honest gaps are PPC and backlinks. SE Ranking has nothing matching Semrush’s ad research, and publishes no backlink index size we could verify, so we are not going to claim parity with either Semrush or Ahrefs on link data.

Verdict: The best swap if you used Semrush mainly for tracking, audits and client reports.

Cheaper than Semrush, deeper on links, narrower on everything else.

Best for: Teams whose core work is backlinks and competitor research

Ahrefs Lite is $129 a month against Semrush’s $139, with a $29 Starter tier below it. So switching from Semrush to Ahrefs is a small saving, not a large one — choose on capability, not price.

On links, Ahrefs is the stronger product and publishes the numbers to argue it: a history of 35 trillion external links, and a live index it says is refreshed every 15 to 30 minutes. Semrush publishes a larger headline figure, but the two count links differently enough that the comparison does not survive scrutiny — Ahrefs has written publicly about exactly this. Do not pick either on index size.

Ahrefs also has the better free tier by a distance, as covered above. That matters for evaluation: you can test Ahrefs on your own site for free, indefinitely, before paying anything.

What you lose is everything outside SEO. No PPC research, no ad-copy history, no social tooling, a thinner content workflow. Ahrefs was built by SEOs for SEOs; if you used Semrush as a marketing platform rather than an SEO tool, this is a downgrade in scope.

Verdict: Switch here if links and competitor research were the point. Stay on Semrush if PPC was.

Mid-price all-rounder at about half of Semrush’s price, with about 27% off annually.

Best for: Solo SEOs who want breadth without the platform price

Serpstat Individual is $69 a month, or $50 a month billed annually — about half of Semrush on either billing — and Serpstat advertises the annual plan as saving $228 a year, about 27%. The entry plan includes five projects, 100 daily searches, 10,000 monthly position checks, 30,000 pages audited and 50,000 export rows.

Those audit and export allowances are genuinely generous for the money. Thirty thousand pages audited a month is not a token figure, and 50,000 export rows compares well against tools costing twice as much.

The 100-searches-a-day ceiling is the thing to plan around. Fine for steady work; frustrating during a research sprint, when you can exhaust it before lunch.

The trial needs a $1 card verification, refunded. Minor friction, but it means you cannot evaluate as freely as SE Ranking’s no-card fortnight.

Verdict: A sensible middle when Mangools is too tight and SE Ranking too close to Semrush’s price.

The honest answer if what you actually used Semrush for was PPC and competitor ad research.

Best for: PPC and competitive intelligence work

Most Semrush-alternative lists ignore PPC entirely, which is strange, because ad research is a large part of what Semrush sells. If competitor ad copy, paid keyword overlap and historical spend were your reason for the subscription, none of the SEO tools above replace any of it.

SpyFu Basic is $39 a month, dropping 25% to $29 on annual billing. It is built for exactly this job: competitor PPC history, ad copy over time, and paid-versus-organic keyword overlap.

The clear trade is that SpyFu is not an SEO platform. Its Site Audit is a recent addition, so you would likely pair it with a free technical stack rather than use it alone.

It is also the only paid tool here with no free tier at all — just a 30-day money-back guarantee. That is a real evaluation cost, though a refundable one.

Verdict: The right swap only if PPC research was the reason you paid Semrush.

The cheapest monthly plan here, level with Ahrefs Starter. Lowest rated tool here — treat accordingly.

Best for: Solo operators and side projects on a hard budget

Ubersuggest Individual is $29 a month for 150 reports a day, one project and 250 monthly credits; the $49 Business plan raises that to 300 reports and seven projects. It is roughly a fifth of Semrush and carries the lowest G2 score of any tool on this page at 4.2. Both facts belong together.

It earns its place in one situation: when the realistic alternative is no tool at all. Knowing which keywords are plausible and which pages are broken beats guessing, and $29 is a much easier decision than $139.

Be careful with the data. Maintaining fresh competitive data is expensive, and cheap tools economise somewhere — usually freshness or depth. Cross-check anything consequential against Search Console and a manual SERP look before acting.

A free account gets 3 searches a day, according to Neil Patel’s own blog, which also lists lifetime access to the Individual plan at $290. The $29 monthly figure is on Ubersuggest’s pricing page.

Verdict: Reasonable against doing nothing. Not reasonable when someone else depends on the numbers.
