Ahrefs and Semrush have swapped punches for a decade, and in 2026 both look different than the blog posts you read last year. Semrush retired its old Pro, Guru, and Business plans for a new four-tier lineup with AI visibility tracking built in. Ahrefs kept its crawl-credit system and added a $29 Starter tier below the classic $129 Lite.
Every number here comes from the two pricing pages as of July 16, 2026. Both tools include one user in the base price and charge real money for extra seats, which is where agency budgets quietly blow up, so the seat table below deserves more attention than the headline prices.
Choose Ahrefs if
Backlinks, competitive research, and site audits are the job and you want the cleanest data-per-dollar path. Lite at $129 covers a serious in-house program; Starter at $29 covers a founder doing their own homework.
Choose Semrush if
You want one subscription for SEO, PPC research, content optimization, and the new AI-visibility tracking. The $139 SEO plan tracks 500 keywords daily across 5 sites, and the suite breadth genuinely replaces two or three point tools.
Bottom line
Ahrefs is the sharper single-purpose instrument. Semrush is the wider platform, and its 2026 AI-visibility push gives it a feature Ahrefs answers only with a pricier add-on. Agencies tend to end up paying for both.

Ahrefs vs Semrush pricing (monthly billing)
| Tier | Ahrefs | Semrush |
|---|---|---|
| Entry | Starter, $29: core site and competitor lookups | SEO, $139 ($117.33 on annual): 5 sites, 500 keywords daily |
| Standard | Lite, $129: 5 projects, 750 keywords, 100K crawl credits | Starter, $199 ($165.17 annual): adds AI visibility, 50 prompts daily |
| Growth | Standard, $249: 20 projects, 2,000 keywords, 500K credits | Pro+, $299 ($248.17 annual): 15 sites, 1,500 keywords, 100 prompts |
| Heavy | Advanced, $449: 50 projects, 5,000 keywords, 1.5M credits | Advanced, $549 ($455.67 annual): 40 sites, 5,000 keywords, 200 prompts |
| Top | Enterprise, $1,499 (annual commitment), uncapped API | Enterprise, custom quote |
Vendor list prices, July 16, 2026. Ahrefs quotes monthly rates and discounts annual billing up to 17 percent. Semrush shows both; annual figures above are its published per-month equivalents. Semrush replaced the long-running Pro, Guru, and Business lineup in 2026, so older comparisons cite plans that no longer exist.
What the money buys, side by side
| Ahrefs | Semrush | |
|---|---|---|
| Backlink index | The reference standard most SEOs trust first | Large index, strong and closing the gap |
| Rank tracking | 750 to 5,000 keywords by tier | 500 to 5,000 keywords, tracked daily |
| Projects / sites | 5 to 50 by tier | 5 to 40 by tier |
| Site audit | Crawl credits: 100K to 1.5M by tier | Included per project with page limits |
| PPC research | Light (ads snapshots) | Full keyword, ad copy, and spend research |
| Content tools | Content Kit add-on from $99/mo | Content optimization included from Starter tier |
| AI search visibility | Brand Radar add-on from $199/mo | Included: 50, 100, or 200 prompts daily by tier |
| Included users | 1 (extra seats $40 to $80) | 1 (extra seats from $45) |
| Free tier | Webmaster Tools for sites you own | Limited free account plus 7-day paid trial |
| Reporting | Report Builder add-on, $99/mo | PDF reports included, white label on upper tiers |
Where Ahrefs is still the sharpest tool
Ask working SEOs which backlink data they trust when two tools disagree and Ahrefs wins the straw poll. The crawler is fast, the index is deep, and Site Explorer remains the quickest route from "competitor ranks for X" to "here is the exact page and link profile that did it." The credit-based site audit scales cleanly: Lite's 100K crawl credits handle most sites under 50K pages without drama.
The pricing philosophy is unbundled. Lite at $129 is honest for one power user, but content optimization ($99 Content Kit), reporting ($99 Report Builder), and AI visibility (Brand Radar from $199) all bill separately, and each extra seat is $40 to $80. A three-person team wanting the full stack can quietly cross $500 a month. The new $29 Starter is a real gift to solo operators who just need lookups without owning the workflow.
Pros
- Backlink index most professionals treat as the tiebreaker
- $29 Starter tier for solo research
- Crawl-credit audits scale predictably
- Fast UI that analysts genuinely prefer
Cons
- Content, reporting, and AI visibility all cost extra
- Extra seats $40 to $80 each
- No PPC research to speak of
- Enterprise jumps straight to $1,499
Where Semrush earns the wider check
Semrush sells breadth: organic research, PPC intelligence, content optimization, local SEO, and social tooling under one login. The 2026 relaunch sharpened that pitch. Every plan from Starter up now includes AI visibility tracking, daily prompt checks of how ChatGPT, Perplexity, and Google AI Overviews describe your brand, which is the feature clients suddenly ask about in every 2026 QBR.
The SEO plan at $139 monthly tracks 500 keywords daily across 5 sites, and daily matters: Ahrefs tracks on looser schedules at comparable tiers. The tradeoffs are density and cost creep. The interface buries good tools three menus deep, per-seat pricing from $45 stings for agencies, and the add-on catalog (reports, lead gen, extra limits) mirrors the upsell energy Ahrefs gets criticized for.
Pros
- One subscription covers SEO, PPC, and content
- AI visibility tracking included from Starter
- Daily rank tracking at every tier
- 7-day trial to test before paying
Cons
- Monthly prices run higher tier for tier
- Interface sprawl slows new users
- Extra seats from $45 add up fast
- Plan renaming makes older advice confusing
The real cost for a small agency
Model a three-person agency running 15 client sites. On Ahrefs: Standard at $249 plus two seats at $60 each is $369 a month, before Content Kit or Report Builder. On Semrush: Pro+ at $299 plus two seats around $45 each lands near $389, with content tools and reporting already inside. Feature-adjusted, Semrush usually prices out slightly better for agencies; data-adjusted, Ahrefs partisans argue the link index is worth the add-ons.
For a solo consultant the answer flips. Ahrefs Starter at $29 or Lite at $129 beats any Semrush entry point for pure SEO work, since the $139 Semrush SEO plan only pulls ahead if you also bill PPC research.
Who should choose Ahrefs
Link-building shops, technical SEOs, and content teams that already have their optimization workflow elsewhere. Also anyone whose buying trigger is trust in the underlying data, because when a migration goes sideways, Ahrefs is the dataset most consultants reach for to prove what happened. Pair it with our AI SEO tools roundup if the missing piece is content automation.
Who should choose Semrush
Agencies selling full-funnel search, in-house teams that answer for both organic and paid, and any brand that needs to show executives how AI assistants describe it. The included AI visibility prompts alone replace a $199 add-on across the street. Semrush is also the safer recommendation for marketers who want one tool to learn rather than three.
Using the trial window well
Semrush gives 7 days; Ahrefs sells Starter at $29 instead of trialing. Use either window on one question: take your three most important pages and your two nearest competitors, and check whether the tool explains the ranking gap in language you could act on. Ignore the dashboards. The subscription that survives is the one whose explanations turn into task lists.
Frequently Asked Questions
Is Ahrefs or Semrush cheaper?
At the entry level, Ahrefs: the $29 Starter and $129 Lite undercut Semrush's $139 SEO plan on monthly billing. At agency scale the gap narrows, since Semrush includes content tools, reporting, and AI visibility that Ahrefs sells as $99 to $199 add-ons. Both charge for extra seats: $40 to $80 at Ahrefs, from $45 at Semrush.
What happened to Semrush Pro and Guru plans?
Semrush replaced them in its 2026 relaunch. The current lineup is SEO ($139), Starter ($199), Pro+ ($299), and Advanced ($549) on monthly billing, with annual discounts. Older comparison articles quoting Pro at $129.95 or Guru at $249.95 describe plans that no longer exist.
Which has better backlink data?
Ahrefs, by professional reputation. Its index and crawler remain the tiebreaker most SEOs cite when tools disagree, though Semrush has closed much of the practical gap. For pure link-building work, Ahrefs is still the default choice.
Does either tool track AI search results now?
Both, priced differently. Semrush includes AI visibility tracking (how assistants like ChatGPT and Google's AI results mention your brand) from its $199 Starter plan, with 50 to 200 tracked prompts daily by tier. Ahrefs sells Brand Radar as an add-on starting at $199 a month.
Is there a real free version of either?
Ahrefs Webmaster Tools is free for sites you verify and covers audits and your own link profile. Semrush offers a limited free account and a 7-day trial of paid plans. Neither free option supports competitor research at working depth.
Which is better for PPC research?
Semrush, and it is not close. Ad keyword data, competitor ad copy, and spend estimates are core Semrush features. Ahrefs shows paid keywords in passing but has never seriously competed for the PPC budget.
How do the rank trackers compare?
Semrush tracks daily on every plan: 500 keywords on SEO up to 5,000 on Advanced. Ahrefs tracks 750 on Lite up to 5,000 on Advanced. Daily granularity at the low tiers is a genuine Semrush advantage for volatile SERPs and client reporting.
Do agencies really pay for both?
Commonly, yes: Ahrefs for link data and audits, Semrush for client reporting, PPC, and now AI visibility. A Lite plus SEO-plan pairing runs about $268 a month and covers the union of strengths, which is often cheaper than pushing either single tool to its upper tiers.
