Top 6 Semrush Alternatives for SEO (2026)

Nobody shops for a Semrush alternative in the abstract. Most people want one of two things: a cheaper or better traditional SEO tool (Ahrefs, Moz Pro, SE Ranking, SpyFu, Ubersuggest and Screaming Frog all compete with Semrush on crawl audits, backlinks and keyword data), or a way to see whether AI engines like ChatGPT, Perplexity, Gemini and Google AI Overviews actually cite their brand. The traditional tools answer that second question only partly, through capped prompt tracking, and it's the one AuditAE is built for. Which one you need determines the answer completely.

The first is price. Semrush's entry plan runs $139/month, the tiers above it climb to $199, $299, and $549, and tracked domains and extra seats add up on top. For a team using four tools out of dozens, that math stops working. (Our Semrush pricing breakdown walks through each plan and what rank tracking really costs per keyword.)

The second is fit. Semrush was built to measure Google's ranked links. When your buyer asks ChatGPT, Perplexity, or Google's AI Overviews a question in your category, that answer is what they see, and Semrush's SEO plan doesn't tell you whether you're in it. Semrush sells that separately: the AI Visibility Toolkit is $99/month for 25 prompts, or it comes bundled in Semrush One from $199.

This guide covers six alternatives. Five are traditional SEO suites, and they're genuinely good at the job Semrush does. The first is built for the second problem. Where each one falls short is included, because a roundup where every tool is excellent is a roundup that helps nobody.

Prices below were checked in October 2026 and are the entry tier billed monthly. Vendors reshuffle plans often, so verify before you buy.

Why look for a Semrush alternative?

• Budget. The entry plan is expensive, extra users and extra tracked domains add up fast, and a lot of the catalog goes unused.
• Complexity. It's a big surface. Plenty of teams need keyword research, rank tracking, and a site audit, not dozens of tools.
• AI search. This is the new one. Classic SEO suites measure your position in a ranked list. Most now add AI prompt tracking on a higher tier or as an add-on, but whether an answer engine named you as the source isn't their core job, and ranking well doesn't mean you get cited.

The right alternative depends on which of those is your reason. Match the tool to the job.

Comparing the top Semrush alternatives

1. AuditAE

AuditAE is the alternative for the reason most people don't see coming: your buyers are starting to get their answers from AI engines instead of the ten blue links, and classic SEO suites treat those answers as an add-on, if they track them at all. AuditAE makes them the core job.

It runs your real buyer prompts against ChatGPT, Perplexity, Google Gemini, and Google's AI Overviews in parallel, and reports whether your brand was mentioned, cited as a source, or quietly skipped, plus your share of voice against the competitors who got cited instead of you. On top of that it bundles the bread-and-butter you'd expect from an SEO tool: Google rank tracking (with AI-Overview citation status per keyword), brand-mention monitoring across AI answers and the open web, technical site audits, and backlink-authority snapshots.

The model is the other half of the pitch. AuditAE is pay-per-use: no subscription, $5 of free credit at signup with no card, a few cents per check, and top-ups that never expire. For a light user or an agency spinning checks up and down across clients, that can cost dramatically less than any monthly seat-based plan.

Where it wins: AI citations are the core job rather than a capped add-on, and the pay-per-use model means an agency can spin checks up for a pitch and down again without carrying a seat all year.

Where it doesn't: it isn't a 1:1 replacement for an all-in-one suite. If you need the deepest backlink index on the market, pair it with Ahrefs rather than replacing Ahrefs with it. It's also newer than every incumbent below, which is a fair thing to weigh.

AuditAE pricing

Pay-per-use. $5 free credit at signup (no card), then 5–12¢ per check depending on the engine (Perplexity 5¢, ChatGPT 7¢, Google AI Overviews 9¢, Gemini 12¢, priced per engine because each one costs us a different amount to run) with no subscription and no expiry on top-ups. See the full rate card and our breakdown of the real cost of Semrush's AI Visibility add-on, which is where the per-check math actually bites.

2. Ahrefs

Ahrefs is the closest like-for-like swap for Semrush's core work, and its backlink index is the reason. If your job involves link building, competitor link gaps, or diagnosing why a competitor outranks you, this is the tool with the deepest data behind the answer. Content Explorer is genuinely useful for finding what's already working in a niche, and the site audit is solid.

Where it wins: link data, full stop. Nothing else in this list is close.

Where it doesn't: the price steps are steep. Starter is deliberately limited, and the jump to Lite is where most teams actually land. AI tracking is thin: Lite includes 5 tracked AI prompts, and Brand Radar is a separate purchase. The sheer surface area overwhelms beginners.

Ahrefs pricing

Starter is $29/month with restricted limits; the Lite plan is $129/month billed monthly, which is the realistic entry point for professional use. There's a free plan (Ahrefs Free) for your own verified sites. The old $7 seven-day trial is long gone.

3. Moz Pro

Moz Pro is the gentlest on-ramp in this list. The interface assumes less prior knowledge than Ahrefs or Semrush, Domain Authority remains the metric most clients recognize by name, and the community and learning material around it are a real asset if you're training someone up.

Where it wins: approachability, and the page-optimization suggestions are concrete enough to hand to a writer.

Where it doesn't: data refreshes less often and the index is smaller than Ahrefs'. Domain Authority is a Moz metric, not a Google one: useful for tracking your own trend, misleading if treated as a score Google cares about. AI prompt tracking starts on the $99 Standard plan (150 prompts, checked weekly).

Moz Pro pricing

The Starter plan is $49/month billed monthly (about $39 on annual billing), with Standard at $99 above it. Moz's pricing page offers a free trial on the Medium plan, not every tier, so check what yours includes.

4. SpyFu

SpyFu specializes in competitive analysis. It's purpose-built for uncovering competitors' strategies, with detailed insight into their keywords and ads. It tracks keyword performance over time with useful historical data, identifies where competitors earn their links, and its keyword-spy tooling surfaces new opportunities. The interface looks straightforward but offers real depth.

Where it wins: the ad-history archive. Seeing which paid keywords a competitor has quietly renewed for six straight years tells you which ones convert, and no general-purpose SEO suite exposes that as cleanly.

Where it doesn't: it's a specialist wearing an all-in-one costume. The backlink database is thinner than its peers', the interface looks a decade old, and its AI Brand Monitoring searches a database of questions SpyFu has already asked ChatGPT rather than tracking prompts you pick. Buy it for competitive intelligence, not as your only tool.

SpyFu pricing

$39/month for the Basic plan billed monthly, which is genuinely cheap for what it does. A limited free view lets you check a competitor domain before paying.

5. Ubersuggest

Ubersuggest, developed by Neil Patel, caters to users who want a straightforward, affordable SEO tool. It excels at generating keyword ideas, includes site audits to pinpoint critical issues, offers basic competitive analysis, and integrates with Google Analytics. Its simplicity makes it especially appealing to beginners and startups on any budget.

Where it wins: price and the absence of a learning curve. For a solo founder who needs keyword ideas and a list of what's broken on their site, it's enough.

Where it doesn't: data granularity. Volume and difficulty estimates drift further from reality than the pricier tools', which matters most on the low-volume long-tail terms a small site should actually target. It has added an AI Search Visibility report, with low limits on the entry plan.

Ubersuggest pricing

The Individual plan is around $29/month billed monthly, tied with Ahrefs Starter as the cheapest subscription here, though the advertised figure moves with promotions and the periodically resurfacing lifetime deal. Check the current number rather than trusting any roundup, including this one. There's a limited free tier.

6. SE Ranking

SE Ranking stands out with a comprehensive, versatile suite that suits all business sizes: rank tracking, keyword research, competitor analysis, and a thorough website audit. For agencies, its white-label reports stand out, letting you hand branded insights to clients. The keyword database is extensive, the interface is clean, and its SEO Task Manager lays out a step-by-step checklist of SEO tasks.

Where it wins: white-label reporting. If you bill clients monthly and the report is part of the product, SE Ranking delivers a branded one for a fraction of what the enterprise suites charge for the same capability. Local SEO coverage is strong too.

Where it doesn't: setup takes real time, and the pricing has a trap: plans scale with your keyword-tracking volume, and white-label reporting is a paid add-on, so the advertised entry price is rarely what an agency actually pays. It has started adding AI-visibility features, but they're a module bolted onto a rank tracker rather than the core job.

SE Ranking pricing

SE Ranking's current plans are Core and Growth, with Enterprise on request, replacing the old Essential/Pro/Business split. Core is $129/month billed monthly ($103.20 annually) and includes 2,000 keywords tracked daily and 100 AI prompts; Growth is $279. White-label reporting is part of the Agency Pack add-on, an extra $69/month, billed annually only. Third-party roundups still quote older, lower figures, so they're out of date. There's a 14-day free trial with no card.

Semrush vs Moz for SEO audits, and where AI citations fit

If you've narrowed it to Semrush or Moz Pro for a site audit (full Semrush vs Moz comparison), the short version: Semrush has the deeper keyword and competitive research and costs more ($139/month entry). Moz Pro is the easier tool to learn ($49/month entry), and Domain Authority is the metric clients recognize. Either one will find crawl errors, broken links and on-page issues.

Neither entry plan tells you whether ChatGPT, Perplexity, Gemini or Google AI Overviews name your brand when a buyer asks a question in your category. Semrush sells that as a $99/month AI Visibility Toolkit (25 prompts), and Moz includes it from the $99 Standard plan. A clean site audit and a strong ranking don't guarantee that. Ranking and being cited are measured separately, so check both: a traditional tool for technical health, and an AI citation check, which AuditAE runs at 5–12¢ per check with no subscription.

Free alternatives to Semrush

On a tight budget, free tools won't match the paid suites but can still deliver real value for basic keyword data and simple audits:

• Google Keyword Planner: keyword volume and ideas straight from Google Ads.
• Bing Webmaster Tools: indexing and keyword data, plus an AI Performance report that shows when Copilot and Bing's AI answers cite your pages.
• Screaming Frog: a free version for technical crawls of up to 500 URLs (the alternatives, compared).
• AuditAE: $5 of free pay-per-use credit, no card, so you can run real AI-citation checks before spending anything.

How to choose the best Semrush alternative for your needs

Selecting the right tool comes down to your reason for switching. Weigh these factors:

• Budget: subscription vs. pay-per-use, and per-domain costs.
• Required features: keyword research, backlinks, site audits, AI-citation tracking.
• Ease of use: how fast your team gets value.
• Customer support and reporting: especially white-label needs for agencies.

A simple way to decide: if you need a deep, traditional all-in-one suite, Ahrefs or Moz Pro is the closest swap, SE Ranking is the agency value pick, and Ubersuggest is the cheapest way in. If your reason for leaving Semrush is price or AI-search visibility, start with AuditAE. It's built for AI-search visibility, and the $5 signup credit covers your first checks.

The short version

Leaving Semrush over cost? Ubersuggest or SpyFu if you need one job done cheaply; Moz Pro's $49 Starter tier if you want a smaller suite at about a third of the price.

Leaving over depth? Ahrefs. It's not cheaper, it's better at the thing you're presumably leaving for.

Running an agency? SE Ranking, for the white-label reports. Price it against your real keyword volume plus the Agency Pack, not the entry tier.

Leaving because your buyers now ask ChatGPT instead of Google? The five suites cover that partly at best, through capped prompt tracking, which is the reason AuditAE exists. If you're not sure it's a real gap yet, the honest test is cheap: run one AI-citation check on a prompt your buyers actually type and see whose name comes back. Often that answer settles the tooling question faster than any comparison table, including this one.

Two free tools to see where you stand, no login: the citation check shows whether ChatGPT, Perplexity, Gemini and Google AI Overviews cite you for a real buyer prompt; the AI search audit shows whether those engines can fetch, read and trust your site in the first place.
