Semrush vs Ahrefs: The Comparison Nobody Has an Incentive to Write

One of these tools pays affiliates $200 to $300 a sale. The other pays nothing at all, because it shut its programme down. Before comparing features, that is worth knowing — it explains a lot about the rankings you will find elsewhere.

Disclosure, and it matters more than usual here: Semrush links on this page are affiliate links and may earn me a commission. Ahrefs has no affiliate programme, so there is nothing for me to earn from recommending it — which is precisely why I want you to notice when I do.

Read this before any comparison, including mine

Ahrefs discontinued its affiliate programme and has stated it has no plans to relaunch it. Semrush runs an active programme on Impact.com paying $200 per SEO Toolkit sale, $300 per Semrush One sale, plus $10 per trial, with a 120-day cookie. Every “Semrush vs Ahrefs” article you find — this one included — has a financial reason to favour one side. The correct response is not to distrust all of them, but to weigh the specific claims rather than the conclusion.

Semrush is now an Adobe company

Adobe announced on 19 November 2025 that it would buy Semrush for $12.00 a share — roughly $1.9 billion, all cash — and completed the deal on 28 April 2026. Semrush's customer FAQ from that day promises “no immediate changes to your current services, agreements, or points of contact”, naming features, interface, access, support and billing, and no changes to existing contracts.

The direction of travel is enterprise: on 17 June 2026 Adobe launched Adobe Brand Visibility inside Adobe CX Enterprise, built on Semrush's AI-visibility data (nearly 300 million AI prompts, 43 trillion backlinks) plus Adobe Experience Manager, with no public pricing. For a buyer today, plans and prices are unchanged as of September 2026. Ahrefs remains independent and privately held.

Head to head

Area	Semrush	Ahrefs	Winner
Keyword database size	28B+ keywords, 142 databases	28.7B keywords, 217 locations, click data	Tie
Backlink index	43T backlinks (Adobe, June 2026)	35T backlinks, refreshed every 15–30 min	Ahrefs
Site audit	Thorough, well organised	Solid	Semrush
Rank tracking	Daily, granular	Good	Tie
Competitor research	Deepest feature set	Strong on links	Semrush
Advertising data	Included	Not a focus	Semrush
Interface	Dense, lots of modules	Cleaner, faster	Ahrefs
Free tier	Limited free account	Free-forever, 6 tools	Ahrefs
Entry price	SEO plan $139/mo ($117 annual)	Starter $29/mo, Lite $129/mo	Ahrefs

Prices as of September 2026, from each vendor's own pricing page. Ahrefs also sells Standard ($249/mo), Advanced ($449/mo) and Enterprise ($1,499/mo, annual commitment); annual billing saves up to 17%. Semrush's $139 plan is now simply called “SEO” — the Pro/Guru/Business names are gone. Both bill in USD with no Indian tier.

Where each one genuinely wins

Semrush wins on breadth

The $139 SEO plan replaces a keyword tool, a rank tracker, a site auditor and a competitor research tool. For someone doing general SEO across several sites, that consolidation is the actual product — not any single feature. Breadth beyond that costs extra: AI-search visibility lives only in Semrush One from $199/mo, and Content, Local, Social, Advertising and Traffic & Market are separately priced toolkits.

The Keyword Magic Tool is the strongest single reason to pick it. Its database is the same size as Ahrefs' (both publish about 28 billion keywords), but nothing else at this price filters long-tail variants and question keywords by intent and SERP feature as well.

Ahrefs wins on depth

If your work involves backlinks — audits, link gap analysis, disavows, outreach targeting — Ahrefs is the tool professionals actually open. The index is deeper and updates faster.

Its click-based metrics are also more honest than raw volume: knowing 1,000 searches produce 200 clicks changes which keywords are worth writing for.

The new battleground: AI search visibility

Both tools now sell tracking of how your brand appears in AI answers, and on both sides it is priced separately from the base plan. Semrush One, launched 29 October 2025, bundles the SEO toolkit with the AI Visibility Toolkit (ChatGPT, Gemini, Perplexity, Google AI Overviews and AI Mode): Starter $199/mo ($165.17 annual, 50 prompts tracked daily), Pro+ $299/mo (100 prompts), Advanced $549/mo (200 prompts). The plain $139 SEO plan does not include it.

Ahrefs' answer is Brand Radar, from $199/mo on top of a subscription. Its 2026 changelog added Grok (April), prompt-based indexes for Google AI Overviews and AI Mode (May), Claude for custom prompts (13 July) and a prompt dataset doubled to 30 million (5 August). Ahrefs also opened its API to free accounts on 16 July 2026 and launched Firehose, a separately priced real-time web-monitoring product.

Neither base plan tracks AI search, so budget $199+/mo on either side if you need it. For an Indian solo blogger it is not yet worth paying for.

The free-tier difference

This is where Ahrefs quietly wins for anyone not ready to spend. Their free-forever plan gives six tools at reduced limits with no card required — enough for occasional backlink checks and basic site health. Semrush's free account is tighter: 10 queries a day in Domain Overview, Keyword Research, Competitor Research and Backlinks, one project, 10 tracked keywords and a 100-page site audit per month.

Ahrefs Free (formerly Ahrefs Webmaster Tools) covers Site Explorer, Site Audit, Web Analytics, Social Media Manager, AI Content Helper and the SEO Toolbar. The first three work only on sites you verify; Site Audit gets 5,000 crawl credits a month, Site Explorer shows up to 1,000 backlinks or keywords per report. “No credit card, no trial period”, in Ahrefs' own words. The cheapest paid step up is the $29/mo Starter plan (monthly-only, 200 credits).

If you are early and unsure, that alone is a reason to open an Ahrefs free account today and defer the paid decision entirely.

Which should you buy?

You do general SEO and want one tool

Semrush. Breadth is the whole value proposition and it delivers on it.

Backlinks are your main job

Ahrefs. Nothing else in this price range matches the link index.

You are early and cautious

Neither yet. Ahrefs' free plan plus Google Search Console covers more than beginners expect.

Your budget is genuinely tight

Neither. Mangools at ~$29.90/mo billed yearly ($49 monthly) does keyword research and rank tracking well enough to start.

If you land on Semrush

Start from a referral link — partner links often carry an extended trial rather than the standard 7 days, which is enough time to test it on your own site properly.

FAQ

Is Semrush better than Ahrefs?

For breadth, yes. Semrush's SEO plan bundles keyword research, site audit, rank tracking and competitor analysis into one subscription, though as of September 2026 advertising, content, local and social are separately priced toolkits. Ahrefs is narrower but deeper on backlinks. If you can only buy one and you do general SEO work, Semrush covers more ground. If link analysis is your main job, Ahrefs wins.

Which has better keyword data?

Semrush's Keyword Magic Tool has a database the same size as Ahrefs' (both publish roughly 28 billion keywords as of September 2026) with better filtering by intent and SERP feature. Ahrefs' keyword data is accurate and its clickstream-based click estimates are genuinely useful — arguably more honest than raw search volume, because they tell you how many searches actually result in a click.

Which has better backlink data?

Ahrefs, and it is not especially close. Their crawler and link index remain the industry benchmark, and for backlink audits, competitor link gap analysis or disavow work it is the tool professionals reach for. Semrush's backlink data is perfectly usable, just not best in class.

Does Ahrefs have a free plan?

Yes — a free-forever plan giving access to six tools with reduced limits, no card required. It is genuinely useful for occasional checks. What no longer exists is the old $7 seven-day trial, so there is no cheap way to evaluate the full paid product.

Which is cheaper?

Ahrefs, to start. As of September 2026 its Starter plan is $29/month (monthly-only, 200 credits) and Lite is $129/month, against Semrush's SEO plan at $139/month, about $117 on annual billing. Semrush's AI-search bundles (Semrush One) start at $199/month. Both bill in USD with no Indian pricing, so forex applies either way.

Why do most comparison articles recommend Semrush?

Partly because it is a genuinely broader product — and partly because Ahrefs discontinued its affiliate programme and has said it has no plans to relaunch. Semrush pays $200 per SEO Toolkit sale and $300 per Semrush One sale. Almost every article comparing them has a financial reason to prefer one. Read accordingly, including this one.

Can I use both?

Agencies often do — Semrush for research and reporting, Ahrefs for link work. For an individual, paying for both is hard to justify; you would be spending upwards of ₹20,000 a month on tooling before writing a word. Pick one, use it properly for six months, then reassess.

What should a beginner in India use instead?

Google Search Console for your own data, Google Keyword Planner for volume ranges, and Ahrefs' free plan for occasional link checks. If you need one paid tool, Mangools at about $29.90/month on annual billing ($49 monthly) covers keyword research and rank tracking at a fraction of either of these.
