Semrush vs. Ahrefs: Which is right for your team?

Both Semrush and Ahrefs offer AI visibility features on top of mature SEO data, so the Semrush vs. Ahrefs decision comes down to how each one collects that data, what it includes at each price point, and how far it stretches as your team grows.

How does Semrush compare to Ahrefs at a high level?

Semrush is built to connect SEO and AI visibility work in one place, while Ahrefs is built around a search index and backlink crawler that many practitioners treat as the reference point for link data.

Both companies publish their database sizes. The more useful comparison is what each platform allows teams to do with that data.

Semrush overview

Semrush is a brand visibility platform that covers keyword research, rank tracking, site audits, backlink analysis, content, PPC, and AI visibility in a single subscription. We have data from 142 geographic keyword databases holding 29.2 billion keywords, a backlink index of 43 trillion links, and an AI Search Database of 317 million prompts across 117 regional databases (as of November 2026).

As an example, we ran the project management software brand Asana through the AI Visibility Toolkit to show how the workflow fits together:

First, the demand: Prompt Research for "project management software" returned 42.4K prompts grouped into about 1,000 topics, with a combined AI volume of 11.4 million.

The report also listed the 19.6K brands mentioned in AI answers for those topics (Asana, Microsoft, and Trello at the top) and the 22.4K source domains AI drew from (led by YouTube, Microsoft, and Reddit).

Next, we ran the Visibility Overview on asana.com. It scored the brand 41 out of 100, with 69.5K mentions and 87.3K citations split across ChatGPT, AI Overviews, AI Mode, and Gemini.

The “Topic Opportunities” tab listed 1.2M topics (ranked by AI volume) where competitors were mentioned and Asana was not. This tells you what content you need to create to fill the gap.

Finally, we ran Site Audit to get an AI Search Health score that checks whether eight AI crawlers (including OAI-SearchBot and Google-Extended) can reach the site. This is important because, if they can’t, then AI can’t pull from your site to recommend you. The tool also flags issues like a missing robots.txt file or pages that are not optimized for AI answers.

Each of these three steps links to the next inside the tool, and you can send prompts found in the first step to Position Tracking for daily monitoring alongside Google rankings.

Two other capabilities stand out:

• The AI Search Database is built from AI search clickstream data and Google's keyword dataset for AI Overviews, so the prompts reflect what people asked AI assistants (rather than keywords rewritten as questions).
• Semrush MCP lets teams query that data (from AI assistants like Claude and ChatGPT), which is included from the Starter plan.

That said, Semrush does have the following limitations:

• Site Audit crawl allowances on the Starter, Pro+, and Advanced plans are smaller than the equivalent Ahrefs tiers, which matters for large sites.
• Brand Performance reports are capped by the number of tracked brands on your plan, so a team analyzing many brands will hit that ceiling.
• API access requires the Advanced plan.

Ahrefs overview

Ahrefs is an SEO and competitive intelligence platform whose core is a web index and backlink crawler, with reported figures of 35 trillion live backlinks, 28.7 billion keywords, and an AI prompt index of more than 525 million monthly prompts across AI Overviews, AI Mode, ChatGPT, Copilot, Gemini, and Perplexity (source: ahrefs.com/vs/semrush, November 2026).

Link-focused audits are a typical example of an Ahrefs use case:

A link builder opens Site Explorer for a competitor, filters the Backlinks report to new or lost links, uses the Best Links filter to cut low-value domains, and inspects the referring page's source to confirm a link exists.

Referring domain graphs update daily, and AhrefsBot ranks first among SEO crawlers by traffic volume on Cloudflare Radar's bot directory. Many practitioners treat Ahrefs as the reference for link data even when they use another platform for everything else.

Ahrefs stands out for a few reasons:

• High Site Audit allowances (100,000 to 1.5 million crawl credits per month on the Lite through Advanced plans)
• API and MCP access is included on every paid plan
• Plan structure is easy to read: three tiers plus Enterprise, with add-ons priced separately

Of course, Ahrefs has some limitations:

• Rank Tracker updates weekly (not daily) on all plans
• There is no free trial; the company states it never runs discounts and offers a limited free plan to verified site owners instead
• AI visibility is only tracked at 5, 10, or 20 prompts on the Lite, Standard, and Advanced plans, with broader coverage through Brand Radar, starting at an additional $199 per month

How do Semrush features compare to Ahrefs features?

Semrush and Ahrefs have comparable capabilities for keyword research, backlink analysis, rank tracking, and site audits, where both platforms cover the same jobs with different data and limits. They differ mostly in AI visibility, advertising research, content tools, and reporting, where the two platforms package and price things differently.

Semrush pricing and limits are from semrush.com/pricing. Ahrefs figures are from ahrefs.com/pricing and ahrefs.com/vs/semrush. All checked November 2026.

Ahrefs also publishes a list of 18 features it says only Ahrefs offers. Several of those have a Semrush equivalent under a different name:

• Comparing rankings between any two dates is the Position Changes report
• Seeing a site's pages and traffic over time is the Top Pages report
• Instant keyword clustering is Keyword Strategy Builder
• Ranking and ad history for a keyword is available through historical data on the Pro+ plan and above
• Daily backlink updates are standard on both platforms, as described in our backlink discovery study
• Checking any brand's AI visibility without setting up prompts is the Visibility Overview report, included on every AI Search plan

Other items on that list are Ahrefs strengths without a direct Semrush equivalent:

• Always-on site audits
• HTML and page-text differences between crawls
• A full list of crawled pages
• A site structure report that does not require a crawl
• AI-written content detection
• A Best Links filter
• Portfolios that group up to 1,000 URLs across domains

How each platform handles AI visibility

Each platform tracks AI visibility with a different data model. Semrush builds a dedicated prompt database and includes AI visibility reports in its SEO plans. Ahrefs builds its AI index from its keyword data and sells most AI visibility through Brand Radar, a product that can also be bought on its own.

Semrush's AI Search Database holds 317 million prompts and responses across ChatGPT, Gemini, Google AI Overviews, and AI Mode, in 117 regional databases.

• Prompts come from AI search clickstream data and Google's keyword dataset for AI Overviews, and responses are captured from real requests rather than model APIs
• Our US database alone holds 130.7 million prompts (with 70.5 million of them on ChatGPT), and the system recognizes 37.1 million brands
• Our prompt database updates on a rolling basis
• Semrush groups prompts into topics and estimates topic-level AI volume and difficulty, which is how Prompt Research works as keyword research for AI answers

Ahrefs reports more than 525 million monthly prompts across what it describes as seven AI indexes (as of November 2026; the figure changes week to week). The breakdown on its comparison page shows about 294 million from Google AI Overviews and 119 million from AI Mode, with ChatGPT, Copilot, Gemini, and Perplexity at roughly 28 million each.

Ahrefs covers more platforms; Semrush holds more ChatGPT prompts (70.5 million vs. about 28 million). Which matters more depends on the model your buyers are using.

Keep in mind that ChatGPT and Gemini together account for nearly 80% of U.S. generative AI chatbot usage, according to First Page Sage. So unless you know your customers are using the other models, chances are they’re on one of these two.

The bigger practical difference between Semrush and Ahrefs is what you can track:

• A Semrush Starter plan tracks 50 custom prompts per day in Position Tracking, Pro+ tracks 100, and Advanced has no daily cap, all alongside Google rankings in the same campaign.
• Ahrefs tracks 5, 10, or 20 prompts on its three core plans, with custom prompt packages sold separately (a $50 package covers about 80 prompts daily on one platform).

For a team that wants to monitor a real prompt set across several platforms every day, Semrush is the clear winner.

In total, here is what a small team pays for SEO plus AI visibility across multiple AI platforms:

• Semrush Starter: $199 per month. Includes 50 tracked prompts per day across ChatGPT, Google AI Overviews, AI Mode, and Gemini, plus MCP access.
• Ahrefs Lite plus Brand Radar: From $328 per month ($129 plus Brand Radar from $199). Includes five tracked prompts on the plan (more require a custom prompt package).

And for teams that also want content optimization and scheduled client reports:

• Semrush Pro+ with Content Toolkit and Pro Report: $379 per month ($299 plus $60 plus $20).
• Ahrefs Standard with Brand Radar, Content Kit, and Report Builder: From $646 per month ($249 plus $199 plus $99 plus $99).

Both totals use monthly list prices. Ahrefs' figure is a floor, since Brand Radar's $199 starting price may not cover every AI platform. Semrush's figure is inclusive for the features listed. Whichever platform you choose, price the add-ons you’ll use in addition to comparing headline plans.

How to choose between Semrush and Ahrefs

To choose between Semrush and Ahrefs, review the work your team does every week rather than focusing on the feature lists. Both platforms cover the core SEO jobs; the differences are in the surrounding workflows, such as AI visibility tracking, client reporting, link auditing, and API access.

Semrush might be the better fit if:

• Your team owns both SEO and AI visibility and wants to see where your brand appears in ChatGPT, AI Overviews, AI Mode, and Gemini without buying a second product
• You report to clients or executives every month and want scheduled, branded reports at a low add-on cost
• You track rankings across Bing or Baidu, or need positions refreshed daily so you can react to volatility the same week (see what rank tracking covers)
• You run paid search alongside organic and want competitor ad research in the same workspace
• You want to test the platform for free before committing to a plan

Ahrefs might be the better fit if:

• Your core work is link building or backlink auditing, and you want the index many practitioners treat as the reference for link data
• You crawl large sites and need higher audit limits on a mid-tier plan without moving to an enterprise contract
• You want API or MCP access on the lowest-priced plan to feed your own tools and dashboards
• You prefer a focused product and do not use content, advertising, or social features
• You already handle AI visibility elsewhere and only need a small number of tracked prompts

Some teams actually run both tools. A common setup is Semrush as the daily workspace for keyword research, rank tracking, AI visibility, and reporting, with an Ahrefs Lite plan for link audits, competitor backlink gaps, and a second opinion on link data.

Semrush vs. Ahrefs: Choose the right tool for your visibility needs

Semrush and Ahrefs both give teams reliable SEO data, and the choice comes down to how much of the surrounding work you want in one place:

• Semrush puts SEO, content, advertising, and AI visibility in one platform, with plans that support solo marketers through to enterprises managing multiple brands
• Ahrefs gives teams a focused, respected set of search and link tools with generous data access at every tier

If your goal is to measure and improve brand visibility across search and AI answers with one subscription, start a free Semrush trial and run the Prompt Research, Visibility Overview, and Site Audit workflow on your own domain.
