Best Semrush Alternatives in 2026 (for SEO and AI Search)

A Semrush alternative is any SEO platform that covers the jobs teams buy Semrush for, such as keyword research, backlink analysis, rank tracking and site audits. It might cost less, focus on fewer jobs, or cover AI search better. That last point now decides most shortlists.

Forrester reports that 95% of B2B buyers plan to use generative AI in at least one area of a future purchase. Our top pick is Mentionova's SEO and AEO platform. It tracks six answer engines, ships fixes with AI agents and can still pull Semrush, Ahrefs, Moz and DataForSEO data.

Below are 12 alternatives, ranked, with prices checked on each vendor's own site in October 2026.

Key takeaways

• Semrush's cheapest paid SEO plan costs $139 a month, and each extra user adds at least $45.
• Mentionova is the best Semrush alternative for teams that depend on AI search as much as Google. It tracks six answer engines and executes the fixes.
• Ahrefs is the closest like-for-like replacement, with 35 trillion historical backlinks and 29 billion keywords.
• Mangools, Serpstat and SE Ranking are the cheapest credible all-in-one options, with entry prices from $18.85 to $129 a month.
• Enterprise teams should compare Conductor (custom pricing) and seoClarity (from $2,500 a month).
• Choose based on the Semrush data you actually use, the AI engines you need and how much execution you want.

What are the best Semrush alternatives in 2026?

The best Semrush alternatives in 2026 are Mentionova for AI search plus SEO execution, Ahrefs for backlink and keyword depth, SE Ranking for value, Similarweb for market intelligence and Moz Pro for authority metrics. Serpstat and Mangools suit tight budgets. Conductor and seoClarity serve enterprise teams.

Why do teams look for a Semrush alternative?

Teams leave Semrush for four reasons: costs that climb with seats and tiers, breadth they never open, AI search tracking sold separately, and data that still needs people to act on it. None of this makes Semrush weak. It is a research suite, not an execution layer.

• Price per seat and limits. The SEO plan costs $139/mo ($117.33 billed annually) for 5 websites and 500 tracked keywords, Pro+ costs $299/mo, and extra users start at $45/mo each.
• Breadth you don't use. Semrush sells eight toolkits, from local to AI PR — idle spend if you only need rankings and research.
• AI search as an add-on. The standalone AI Visibility toolkit costs $99/mo per domain, billed annually, for 25 prompts across ChatGPT, Google AI, Gemini and Perplexity.
• Execution, not just data. 60% of digital leaders cite executing at scale as their biggest SEO challenge.

Semrush has still earned its reputation: it reports over 28 billion keywords, 43 trillion backlinks and 142 geographic databases, and it offers a free plan and a 7-day trial.

How does Semrush compare with Mentionova?

For a fuller breakdown, see Mentionova's Semrush comparison page.

1) Mentionova

Mentionova is a complete SEO and AEO/GEO platform built around Nova, an AI agent you ask for an outcome instead of a report. It tracks how answer engines describe your brand, finds the pages that are slipping and ships the fixes. It suits in-house teams and agencies whose growth now depends on AI search as much as Google.

Best for: Teams that want one platform to track AI and Google visibility and act on it, with or without Semrush in the stack.

Key capabilities

• An AI Visibility Tracker for six engines (ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews and Reddit), with share of voice against named rivals.
• AI Brand Monitoring that scores sentiment, fact-checks answers and flags wrong ones.
• 100+ AI growth agents, with 23 workflow templates and 13 grid templates in every workspace. Nova can also build a new agent from a plain-language description.
• A Content Optimizer for slipping pages that merges Search Console, AI citations and the live SERP, then writes a refresh brief.
• Internal linking, Article/Breadcrumb/FAQ schema, content gap analysis, keyword clustering, and an AI Content Writer that links stats to their sources.
• White-label SEO and AI reports assembled weekly, with agency reporting for every client from one login.

Why it ranks #1

Semrush tells you where you stand, while Mentionova also decides what to ship next and then does the work. Anything that ships waits for your approval, and every step and tool call is logged. That closes the gap between data and execution that most Semrush users hit.

You also don't have to rip out Semrush. Mentionova's integrations catalogue lists Semrush, Ahrefs, Moz and DataForSEO as data sources, alongside Search Console, GA4, WordPress and Webflow. Setup needs no pixel or tag, only your domain and buying questions. The first Growth Signal arrives in about 2 minutes, and Mentionova says citation lift usually lands in 30–60 days.

Pricing

Starter costs $99/mo billed annually ($125 monthly) for 100 agentic tasks, 25 prompts and 3 engines. Scale costs $320/mo ($400) for 500 tasks, 100 prompts and all 6 engines, and Enterprise costs $799/mo ($999). Every paid plan includes a free trial that needs no card.

2) Ahrefs

Ahrefs is the closest like-for-like Semrush replacement: a research suite built on its own crawler that covers backlinks, keywords, rank tracking and site audits. It suits SEO teams focused on link analysis and competitive research who want AI visibility data from the same vendor.

Best for: Link-focused SEO teams and agencies.

Key capabilities

• 35 trillion historical backlinks and 29 billion keywords across 217 locations.
• Site Explorer, Keywords Explorer, Rank Tracker, Site Audit and Web Analytics.
• Brand Radar and tracked AI prompts, with Brand Radar AI from $199/mo.
• API and MCP access on every core plan.

Pricing

Starter costs $29/mo, Lite $129/mo, Standard $249/mo, Advanced $449/mo and Enterprise $1,499/mo on an annual commitment.

Where it falls short

Core plans track only 5–20 AI prompts, and extra users cost $40–$100/mo each. Mentionova's Ahrefs comparison maps the overlap.

3) SE Ranking

SE Ranking is an all-in-one SEO and GEO platform that costs less than Semrush and puts rank tracking, research, audits and AI search tracking in one plan. It suits small marketing teams and agencies that want most of Semrush's everyday tools without paying for higher tiers.

Best for: SMBs and agencies on a budget.

Key capabilities

• Rank tracking plus unlimited keyword, competitor and backlink research.
• 100 AI prompts tracked daily across 5 LLMs on Core.
• A white-label Agency Pack for $69/mo, billed annually.

Pricing

Core costs $129/mo ($103.20 billed annually) and Growth $279/mo ($223.20), with a 14-day free trial that needs no card.

Where it falls short

Core includes one manager seat and keeps only 6 months of historical data, and extra seats start at $16 each.

4) Similarweb

Similarweb is a market intelligence platform best known for traffic and engagement data on any website, and it now bundles SEO and AEO suites. It suits strategy and growth teams that care more about cross-channel market share than daily rank tracking, the job Semrush's Traffic & Market toolkit does.

Best for: Market and competitor traffic analysis.

Key capabilities

• Traffic and engagement benchmarks, channel breakdowns and competitor alerts.
• SEO Intelligence covering organic overview, keyword research, rank tracking, site audit and backlinks.
• AEO Intelligence covering AI brand visibility, sentiment, citations and AI traffic.

Pricing

The tier that adds SEO and AEO is listed at $333/mo billed annually ($399 monthly), though prices vary across Similarweb's own pages.

Where it falls short

That tier includes one user seat and 6 months of history, so costs climb as a team grows.

5) Moz Pro

Moz Pro is one of the longest-running SEO suites, known for Domain Authority and, more recently, Brand Authority. It suits small businesses and in-house marketers who want clear authority metrics, rank tracking and a light AI visibility layer for less than Semrush charges.

Best for: Authority metrics on a budget.

Key capabilities

• Keyword Explorer with 1.25 billion+ keywords and Link Explorer with over 40 trillion links.
• AI Visibility dashboards tracking 150 prompts across 4 AI models on Standard.
• Rank tracking, site crawls, AI content briefs and MozBar Premium.

Pricing

Starter costs $49/mo for one site, Standard $99/mo ($79 billed yearly), Medium $179/mo and Large $299/mo.

Where it falls short

Prompts refresh weekly rather than daily, and the keyword index is far smaller than Semrush's 28 billion.

6) Search Atlas

Search Atlas is an SEO platform built around OTTO, an AI agent that makes technical fixes, on-page changes and content updates on your site. It suits agencies and lean teams that want execution inside the tool. You pay with a monthly pool of Universal Credits.

Key capabilities

• OTTO SEO for automated technical and on-page fixes.
• Content Genius and an AI content suite that publishes to any CMS.

Pricing

Starter costs $99/mo, Growth $199/mo, Pro $399/mo and Agency from $999/mo, with a 7-day trial.

Where it falls short

Starter includes no LLM visibility projects, and credit-based billing makes monthly spend harder to forecast.

7) Serpstat

Serpstat is an all-in-one SEO platform that bundles keyword research, rank tracking, site audits and backlink analysis for less than Semrush. It suits freelancers and small agencies that want keyword clustering, an API and a basic LLM brand monitor without paying enterprise prices.

Best for: Budget team plans.

Key capabilities

• Keyword research, site analysis, rank tracking, audits and backlink analysis on every plan.
• Keyword clustering and an LLM Brand Monitor.
• An API, an MCP integration with ChatGPT and Claude, and an AI Overview Brand Opportunities report on Team plans.

Pricing

Individual costs $69/mo, Team $129/mo, Team x2 $209/mo and Agency $499/mo. Annual billing cuts those to $50, $100, $169 and $410 a month.

Where it falls short

Individual allows only 100 searches a day, and the 7-day trial needs a card for a refunded $1 verification charge.

8) SpyFu

SpyFu is a competitor research tool focused on the keywords and Google Ads your rivals have bought and ranked for. It suits PPC managers and growth teams that want to copy what already works, at a fraction of Semrush's price.

Best for: PPC and competitor keyword research.

Where it falls short

Basic caps search results and exports at 10,000 rows and allows one tracking project.

9) Conductor

Conductor is an enterprise AEO and SEO platform that combines content creation, search intelligence, site monitoring and an agent layer. It suits large in-house teams that need governance across many websites and prefer usage-based pricing to buying licenses seat by seat.

Best for: Enterprise AEO and SEO programs.

Key capabilities

• Conductor Intelligence for visibility in traditional and AI search.
• Conductor Creator for AI content, with a writing assistant and internal link recommendations.
• Conductor Monitoring for 24/7 website health.
• AgentStack, which feeds AEO data into LLMs, apps and agents.

Pricing

Custom pricing. Essentials offers a free trial, while Growth and Enterprise start with a demo.

Where it falls short

No prices are published, and Essentials caps you at 500 tracked keywords and 3 websites.

10) seoClarity

seoClarity is an enterprise SEO platform that covers rank tracking, content, technical audits and an AI search module called ArcAI. It suits global SEO teams with many domains, heavy technical needs and a budget for hands-on help. Professional services come with every engagement.

Best for: Enterprise technical SEO.

Key capabilities

• Rank tracking with unlimited competitors.
• Technical SEO with unlimited crawl pages and log-file analysis.
• ArcAI for AI search visibility, AI Overviews tracking and AI bot activity.

Where it falls short

With a $2,500/mo starting price, it is out of reach for most small teams.

11) Surfer

Surfer is a content optimization platform that scores drafts against the pages that already rank, and it now tracks brand visibility in AI answers. It suits content teams that mainly used Semrush for writing and on-page work rather than backlink research.

Best for: Content optimization.

Key capabilities

• A content editor for creating and optimizing documents.
• AI Search Analytics across ChatGPT, Gemini and AI Overviews.
• 1-click internal linking, coverage gap and cannibalization reports on Pro.
• A plagiarism checker and rank drop detection on Standard.

Pricing

Where it falls short

Standard refreshes its 25 AI prompts weekly, and daily tracking starts on Pro.

12) Mangools

Mangools is a beginner-friendly bundle of five SEO tools plus an AI Search Watcher, priced well below Semrush. It suits bloggers, solopreneurs and freelance SEOs who need keyword ideas, SERP checks and light rank tracking without a steep learning curve or a big monthly bill.

Best for: Beginners and freelancers.

Key capabilities

Pricing

Basic costs $30.50/mo, or $18.85/mo billed annually, while Premium costs $26.35/mo and Agency $48.85/mo on annual billing.

Where it falls short

Basic allows 100 keyword lookups a day and no extra seats, and rank updates are weekly on every plan except Agency.

How do you choose the right Semrush alternative?

Choose by workflow, not feature count, using these four questions.

Which Semrush data do you actually use?

Review a month of Semrush usage before you shop. If you live in backlink reports, Ahrefs is the natural swap; if you mostly track rankings, SE Ranking or Serpstat costs less. Rankings still matter, since 76% of AI Overview citations come from pages in Google's top 10.

How many AI engines does it track?

Count the engines, then check how often each refreshes. Semrush's AI toolkit covers four engines, and Moz tracks four models weekly. Mentionova adds Claude and Reddit, for six engines on its Scale plan. Our ranking of AI visibility tracking tools compares 15 trackers.

Does it ship fixes or just report?

A report only helps if someone acts on it. Search Atlas's OTTO applies on-site fixes. Mentionova runs 100+ agents that draft content, add schema, suggest internal links and publish to your CMS after approval. If you'd rather hand the work to people, an SEO and GEO program covers both.

What will it cost at your team size?

Price your real seat count and prompt volume, not the entry tier. Semrush charges from $45/mo per extra user and Ahrefs from $40/mo, while Conductor and Search Atlas bill by usage or credits. Model a full year of spend before you sign.

Why does Mentionova lead this list?

Semrush is still a strong research database, but in 2026 growth depends as much on citations in ChatGPT, Perplexity, Claude, Gemini and Google AI Overviews as on blue links. Mentionova wins because it closes the whole loop: it tracks six engines, diagnoses what slipped and ships the fix through agents, with a human approving each change.

It also works with your existing stack. You can keep Semrush or Ahrefs as a data source and run Mentionova as the operator on top. Connor Nowinski, COO at 11x, put it simply: "In two months we tripled our inbound leads and AI search traffic."

• Six answer engines, including Claude and Reddit.
• 100+ agents, 23 workflow templates and 13 grid templates.
• No pixel or code install, and a first Growth Signal in about 2 minutes.
• White-label weekly reporting for agencies.
