Ahrefs vs Semrush: which to pick, job by job

This guide is for people who have decided they need a paid SEO suite and are stuck between the two big ones. Freelancers in India pricing their first retainer, agencies choosing a tool for the team, in-house marketers asked to justify the spend, and small business owners who keep hearing both names. If you haven't used either, read our Semrush guide and Ahrefs guide first, or at least their first chapters. This one assumes you know what a backlink, a keyword gap and a rank tracker are.

You'll be able to pick one for your situation, explain the choice to a client or a boss, and know what the cheapest plan that does your job really costs. You'll also see which jobs the free tiers already cover, and when neither tool is worth paying for.

We start with the short answer by situation. Then come where each tool's data comes from and what you get free. Chapters 3 and 4 go job by job: keywords, backlinks, competitors, site audit, rank tracking, AI visibility and local. After that, prices, limits and add-ons, and last, how to switch or run both. There's a 10-question quiz and an FAQ at the end.

Every fact here comes from our two fact-checked tool guides and the vendors' own pages. Prices were read on Ahrefs'^[1] and Semrush's^[2] pricing pages on 16 October 2026 and checked again on 18 October 2026. Nothing had changed. Neither company pays us, and there are no affiliate links in this guide.

Ahrefs and Semrush do the same core work. Both estimate any site's keywords, traffic and links, audit your own site, track rankings and now measure AI visibility. Most people would get their job done in either. The differences that decide it are narrower than review sites suggest. They are the price of the first useful plan, whether you need mobile and city-level data, how many people will log in, and whether you also research Google Ads or local search.

So here's our pick for each situation first, with the reasons. The rest of the guide shows the evidence, job by job.

Our pick by situation

Rupee figures are ours, at ₹96 to the US dollar, and both vendors list prices in US dollars before tax (chapter 5).^[1] Semrush's prices are on its own page.^[2]

Small business in India: neither, yet

We'd tell a Kanpur sweet shop or a single-clinic Delhi dentist with a 20-page site not to buy either. Both of our tool guides say the same. Your first problems are almost always on your own site: pages not indexed, slow mobile pages, weak titles, an unclaimed Business Profile. Search Console shows what Google saw. Ahrefs Free audits your verified site and shows its links and keywords at no cost. Semrush's free account gives 10 reports a day for a look at a few competitors. Chapter 2 shows exactly what each free tier covers.

Pay when you've fixed the basics and your next question is about competitors. Our freelancing chapter gives freelancers the same rule: buy a plan when a client's fee pays for it.

Freelancer in India: start cheap, then follow your clients

Ahrefs Starter at $29 (about ₹2,784) is the cheapest way into either tool's competitor data. It adds Keywords Explorer, Rank Tracker and a look at any site, inside 200 credits a month. It has no exports, no extra users and 250 rows per report, so it's a learning plan, not a client plan.^[3]

Once clients pay, the choice depends on what they buy from you:

• Link building and content: Ahrefs Lite at $129. It adds Content Gap and Link Intersect, exports and 750 tracked keywords. Credits run out if you open reports carelessly (chapter 5).
• Local SEO for clinics, coaching centres and shops: Semrush's SEO plan at $139. Position Tracking checks rankings daily down to a city or postal code,^[4] picks up the local pack,^[5] and India has a mobile database.^[6] Ahrefs' Rank Tracker can also go down to a city or ZIP code on mobile, but it updates weekly by default, and its Organic keywords report is desktop only, at country level.^[7]

Agency: Semrush if you report AI and local, Ahrefs if you sell links

Semrush's Starter plan ($199) is the cheapest plan of either tool that tracks dozens of AI prompts inside the plan: 50 a day, plus the SEO Toolkit.^[2] Ahrefs Lite includes only 5 custom prompts (chapter 4). Pro+ ($299) adds 15 websites, 1,500 tracked keywords and multi-location tracking. Its add-ons fit agency work: extra users from $45, and white-label Pro Reports at $20 each a month.

An agency whose main product is links or content can do more with Ahrefs Standard ($249): unlimited credits, Content Explorer, Portfolios and Broken backlinks.^[1] Extra users there cost $60 each a month, up to five.

In-house team: pick by your main job

For an in-house team the price gap matters less than the fit. If your company also runs Google Ads, Semrush shows a snapshot of competitors' paid search in Domain Overview (full ad research is the separate Advertising Toolkit).^[8] If you own a large content site, Ahrefs' traffic potential and parent topic make content decisions faster. Pro+ and Standard both keep historical data. Run Search Console beside either one; nothing in either tool replaces Google's own numbers for your site.

Content team: Ahrefs, with one condition

Ahrefs' content features sit on Standard and up: Content Explorer, a search engine over about 22.6 billion pages by Ahrefs' count, and keyword clusters by parent topic.^[9] The condition is budget. Below Standard, Semrush's Keyword Strategy Builder groups up to 10,000 keywords into pillar pages and subpages on any paid plan.^[10] Its SEO Writing Assistant allows only 2 documents below Pro+, though.^[11]

Chapter 2 starts with the question under all of this: where each tool's numbers come from, and how much to trust them.

Every comparison article ends up arguing about whose data is "bigger" or "more accurate". Neither page settles it. Here's what each company says, what it actually measures, and how to test it on your own site in ten minutes.

What each vendor says about its data

We read both pages again on 18 October 2026, and the figures matched our two tool guides.

Read that table carefully before you quote it. The numbers don't count the same thing. Ahrefs' 35 trillion is "backlinks history", every link it has ever recorded. Semrush's 43 trillion is the size of its database. Semrush's 28.8 billion keywords is a total across all its countries; Ahrefs publishes country figures instead. Neither company says how many of those links are live today, or how many keywords have real search volume in India. So "Semrush has more backlinks" is not something either page proves.

What Google says about both

Google's own guidance covers every tool like these: "Third-party tools don't have access to our internal ranking data."^[17] Authority Score, Domain Rating, KD and KD% are the vendors' own scores. Traffic for a site you don't own is an estimate in both: Ahrefs calls its Organic traffic "an estimation",^[18] and Semrush's traffic figures are estimates too, built from its ranking data and, in Traffic & Market, a clickstream panel.^[13]

That's why the fair test is your own site, not a vendor's page.

Do it on two or three sites if you can. One site proves very little.

The free tiers, side by side

Both free tiers are useful, but for opposite jobs. Ahrefs Free goes deep on sites you own and shows nothing about anyone else's. Semrush's free account shows any site, but only 10 reports a day with about 10 rows each.

Sources: Ahrefs' Webmaster Tools page,^[19] its Free page^[20] and its free-use list;^[21] Semrush's pricing page,^[2] its free account article,^[22] its Backlinks limits^[15] and its Keyword Magic Tool limits;^[23] Semrush's AI features guide for the AI row.^[24] Our Ahrefs guide, chapter 2 and Semrush guide, chapter 2 set each one up step by step.

How we'd use the two together, for free

For a small site, run both. Verify your site in Ahrefs Free and let its Site Audit crawl weekly; that's a fuller audit than Semrush's 100 free pages. Use Semrush's 10 daily reports for competitors: one Domain Overview per competitor, then Organic Rankings sorted by traffic.^[22] Ahrefs' free tools on its website, such as the Backlink Checker (top 20 backlinks of any site) and the SERP Checker, fill a few more gaps.^[25]

There's one difference in what happens if you try a paid plan. Semrush gives a 7-day free trial on paid plans, but exports are off during it.^[26] Ahrefs has no trial. Its pricing page says "We never run discounts" and points website owners to Ahrefs Free instead.^[1]

Next, the jobs themselves, starting with keywords, backlinks and competitor research.

This is the work most people buy a suite for. Each job below has a table, then our view. The details of each report are in the two tool guides, and we link to the right chapter every time.

Keyword research

Our view: for a business selling in India, Semrush's mobile India database is a real advantage. If your customers search on phones, that matters, and Semrush keeps a separate mobile database for India.^[6] Ahrefs' Organic keywords report, which shows what a site ranks for, is desktop only and country level.^[7]

Ahrefs wins on one decision: whether a keyword needs its own page. Parent topic tells you which broader search the top page actually gets its traffic from. If "jee coaching fees in pune" has the parent topic "jee coaching in pune", one strong page can answer both. Traffic potential then estimates what that top page earns across all its keywords.^[34]

Don't compare the difficulty scores. A KD of 30 in Ahrefs and a KD% of 30 in Semrush come from different models. Ahrefs counts only the links to the current top 10.^[29] Guide 2, chapter 1 explains why you compare difficulty only inside one tool.

Volumes are estimates in both. Ahrefs tested its own volumes against Search Console impressions and found them roughly accurate for 60% of keywords studied, against 45% for Keyword Planner. That's a vendor testing itself.^[35] Semrush's volumes are also its own estimates, and small Indian local searches are often thin in both. Full detail: Ahrefs guide, chapter 4 and Semrush guide, chapter 4.

Backlinks

Sources for the free and freshness rows: Ahrefs' Free page,^[19] its links database article,^[14] and Semrush's Backlinks article.^[15]

Ahrefs started as a backlink checker and links are still why most people buy it, as our Ahrefs guide puts it. That reputation is earned by habit and by its clear metrics. It isn't proven by an independent test we could find (chapter 2). Semrush's link data is good enough for outreach lists. For most Indian small businesses, the difference between the two link indexes matters far less than what you do with the list.

Both site scores are the vendors' own. Ahrefs says you can't call a DR "good" in absolute terms, only against similar sites.^[36] Semrush says Authority Score is "best used for domain comparison".^[37] Never compare a DR with an Authority Score.

On Backlink Audit we hold the same line as our Semrush guide: Google's disavow page says "most sites will not need to use this tool".^[39] So the "toxic" score is not a reason to pick Semrush. No manual action and no history of bought links means no disavow file.

Competitor research

Ahrefs' Starter plan has no Competitive Analysis, so its cheapest gap tool sits on Lite.^[27] Semrush's Keyword Gap groups keywords as Missing, Weak, Untapped, Strong, Unique and Shared, and a page-two filter (positions 11 to 20) gives a ready starting list. Comparing folders or URLs and looking at history need its higher tiers.^[41]

Our view: for a Pune coaching centre's agency comparing four rival institutes, both do the job at a similar price (Lite $129; Semrush's paid plans from $139, with Starter at $199 the first one whose tool list we could confirm). Choose Semrush if those rivals also run Google Ads and you want a look at their paid search in the same account. Choose Ahrefs if you want more than four competitors in one gap report. Step-by-step versions: Semrush guide, chapter 3 (Keyword Gap for a coaching centre) and Ahrefs guide, chapter 7 (Content Gap for a D2C brand).

Chapter 4 covers the jobs on your own site, plus AI visibility and local search.

These jobs are about your own site, so the free tiers matter more here, and the gaps between the two tools are clearer than in chapter 3.

Site audit

Sources: Ahrefs' pricing page,^[1] rows and limits article^[46] and crawl settings article;^[47] Semrush's Site Audit article^[45] and AI features guide.^[24]

Our view: for a small site, Ahrefs Free is the better free audit by a wide margin, and it costs nothing on every site you verify. Semrush's audit is the one to use if you're already paying for Semrush, and its AI Search checks are handy. Neither replaces a desktop crawler on a large site; our Screaming Frog guide covers that. Whatever the audit says, confirm the serious issues in Search Console, which shows what Google actually did.

Don't chase either tool's health score. Both are the vendors' summaries, and the last points are often notices that change nothing.

No paid account at all? Our Free Website Audit runs 50+ checks across 25 pages for SEO, speed, security, AI visibility and local SEO; sign in free with Google or your email for the full fix list, with the points each fix adds, and a PDF.

Rank tracking

Sources: Ahrefs' Starter article^[3] and update frequency article;^[48] its Rank Tracker page;^[49] Semrush's Position Tracking article^[4] and set-up guide.^[5]

This is the clearest split in the whole comparison. If your client asks "where do we rank in Lajpat Nagar on a phone today?", Semrush answers it daily. Ahrefs answers it once a week. We think weekly is fine for most SEO work, because daily checks mostly show Google's normal wobble. But local clients watch the local pack closely, and agencies get asked.

Two Semrush limits catch people out: location and device can't be changed after the campaign starts, and tracking several cities in one campaign needs Pro+.^[5] In Ahrefs, keep in mind that Site Explorer's own keyword positions are desktop and country level; for a city on mobile you need Rank Tracker.^[7] Guide 2, chapter 11 explains how to use a tracker beside Search Console's average position.

AI visibility

Sources: Ahrefs' pricing page^[1] and Brand Radar article;^[51] Semrush's AI features guide,^[24] AI Visibility Toolkit article^[52] and Data and Metrics page.^[13]

For an agency that has to report AI visibility, Semrush is simply cheaper to start. Moving from its $139 SEO plan to $199 Starter adds 50 tracked prompts a day; on Ahrefs, the AI index costs $199 a month per platform, on top of a plan or on its own with Ahrefs Free. If you're on Ahrefs Lite already, use its 5 included prompts for your five most important buyer questions. Lite's allowance runs them daily on one platform, or weekly across several, which is what our Ahrefs guide suggests.

Trust both the same, which is not much on any single day. Both run their own prompts on a schedule; neither sees what real people asked. Google says: "No third-party tool has access to our internal ranking or AI systems."^[53] Ahrefs also warns its index "may have limited coverage for brands with little or no search volume",^[54] which describes most Indian small businesses. Start with the free reports in Guide 5, chapter 8, and check AI crawlers can reach you first.

Our checker tests whether GPTBot, ClaudeBot, PerplexityBot and 117 more bots can access your site, with an AI readiness score and a robots.txt fix.

Local search

For a Delhi dental clinic or a Kanpur sweet shop, Semrush is the better paid tool for local work, mainly because of daily local pack tracking. Our two tool guides don't test Ahrefs' GBP Monitor or Semrush's Local Toolkit in depth, so we won't rank them. Most local wins still come from a free Google Business Profile done properly, reviews and citations, as Guide 2, chapter 10 explains.

Chapter 5 puts every plan, limit and add-on of both tools in one place, with rupee figures and the GST notes.

We read both pricing pages from India on 16 October 2026 and again on 18 October 2026. Both showed US dollars only, and no price had changed between the two dates.^[1] Semrush's figures are from its own page.^[2] Rupee figures are ours, at ₹96 to the US dollar, the X-Rates monthly average for 1 to 16 October 2026, rounded and before tax.^[56] Your card statement will differ with your bank's rate and fees.

The plans, matched by price

Sources: both pricing pages; Starter's limits from Ahrefs' help article on the plan.^[3] Ahrefs counts only unverified projects against the limit, so every site you verify is free on any plan. Semrush counts "websites to monitor": one slot per site with Site Audit, Position Tracking or a few other tools switched on, while creating a project by itself uses no slot.^[57]

Paying yearly

Both pages say yearly billing saves "up to 17%". Semrush shows the yearly price per month on its page. It's $117.33 for SEO (about ₹11,264), $165.17 for Starter (about ₹15,856) and $248.17 for Pro+ (about ₹23,824), paid as one amount upfront.^[2] Ahrefs' page doesn't list yearly prices per plan; its FAQ says to contact support to switch to annual billing.^[1] Our advice is the same for both: pay monthly until you've used the tool on real client work for two or three months.

Users, credits and the costs that grow quietly

On Ahrefs Lite, every user who opens reports is billed by use. A user with 0 to 5 credits in a month is free, 6 to 100 is a "Casual" user at $20, and above that a "Power" user at $40.^[58] Starter has no extra users and you can't buy more credits. On Lite, pay-as-you-go extra credits cost $50 per 500 if you switch them on. Leave that off until you know your monthly use.

What a two-person team pays a month, before GST, on four plans people often compare:

Don't share one login to save the seat. Ahrefs says shared access breaks its terms and can get the account blocked.^[59]

Add-ons

Sources: both pricing pages, Semrush's AI Visibility Toolkit article,^[52] its Local Toolkit pricing^[55] and its Content Toolkit pricing.^[60]

Trials, refunds and paying from India

Sources: Ahrefs' pricing FAQ,^[1] GST article^[61] and currency article;^[62] Semrush's subscriptions,^[26] refund,^[63] billing^[64] and tax pages.^[65]

The trial difference matters more than it looks. With Semrush you can try a paid plan for a week, but you must cancel before day seven or it becomes the paid plan you chose,^[26] and a monthly plan isn't covered by the refund.^[63] With Ahrefs you can't try a paid plan at all, so test everything on Ahrefs Free, then buy one month of Starter or Lite.

Chapter 6 covers switching from one to the other, running both, and the jobs where free tools, including ours, are enough.

People switch for three reasons: the price went up, a new client needs something the old tool lacks, or a new hire knows the other tool. Whatever the reason, the switch costs you history. Plan it so you lose as little as possible.

Before you cancel the old tool

Sources: Ahrefs' Starter article,^[3] Semrush's subscriptions article,^[26] projects article^[57] and Position Tracking set-up,^[5] and Ahrefs' pricing FAQ.^[1]

Ahrefs' Rank Tracker can import past rankings from Site Explorer when you add keywords, but only desktop data in your main location.^[7] Semrush's Position Tracking can import keywords from a file, Google Analytics or Search Console.^[5] Neither imports the other tool's rank history. So the old reports, exported as files, are your record.

Paying for one, using the other free

You don't have to choose only one. Many setups work well with one paid plan and the other tool's free tier:

• Semrush paid, Ahrefs Free beside it: verify your clients' sites in Ahrefs Free for a second audit and a free view of their own backlinks. This is the pair we'd suggest for a local SEO freelancer.
• Ahrefs paid, Semrush free beside it: use Semrush's 10 daily reports for a quick look at a rival's paid search traffic, or the mobile India database, which Ahrefs' Organic keywords report doesn't have.
• Both paid: only when clients pay for both kinds of work, such as a link-building retainer and a local SEO retainer. Below that, the second bill buys you mostly the same data.

Where our free tools cover the job

Neither suite is needed for some jobs. Our free tools need no paid account and do these:

We don't have a backlink, keyword volume or rank tracking tool yet. For those, the free choices are Search Console's Links report (a sample of links),^[66] Google Keyword Planner and Search Console's average position. Our Best free SEO tools guide lists them by job, and our Search Console guide shows what Google's own data can and can't tell you.

Other suites worth a look

If neither price works, cheaper suites do parts of the job: SE Ranking for rank tracking, Mangools and Ubersuggest for keywords on a budget, and Moz Pro. Each has its own guide in this path.

And if you'd rather not pay for any tool, our SEO service runs this research for you; you can get a quote in a couple of minutes. Otherwise, go back to the table in chapter 1, pick your row, and open that tool's free tier today.
