Seven Semrush alternatives are compared here, including Ahrefs, Moz, Mangools, SE Ranking and free tools.

TL;DR · LAST REVIEWED 21 July 2026
- Disclosure: Kael Tripton uses Semrush for its own research, referenced in this guide alongside independent pricing and feature comparisons.
- Ahrefs is the closest feature-for-feature competitor to Semrush, with a stronger backlink index but a higher starting price and no native LLM visibility tracking.
- Moz Pro is generally the easiest platform to learn, aimed at beginners and smaller teams, though it has fallen behind on some advanced features.
- SE Ranking and Mangools both offer flexible, lower-cost pricing tiers based on keyword volume rather than Semrush's flat-tier structure.
- Semrush includes daily rank tracking on all plans by default, an advantage over platforms that charge extra or restrict tracking frequency on lower tiers.
- Free and low-cost tools such as Ubersuggest can cover basic keyword research needs but lack the depth of paid platforms for competitive or technical analysis.

What is the closest alternative to Semrush
Ahrefs is generally considered the closest feature-for-feature competitor to Semrush, with a larger backlink index and faster link discovery, though it starts at a higher entry price and does not natively track brand visibility within AI search results in the way Semrush does.
Ahrefs and Semrush are the two platforms most frequently compared head to head in the UK SEO market, since both aim to cover keyword research, backlink analysis, site auditing and competitor tracking in a single subscription. Ahrefs has built a reputation for a larger and faster-updating backlink index, which matters most for link-building-focused work and for agencies where backlink accuracy is the primary use case. Ahrefs' entry-level Starter plan runs from around $29 a month on a credit-based system with fairly limited monthly usage, stepping up to a Lite plan from around $129 a month for more complete access to its core tools. Semrush's own entry-level Pro plan starts from around $139.95 a month, a similar order of magnitude to Ahrefs Lite, with the practical choice between the two often coming down to whether backlink depth or all-in-one marketing breadth, including paid search and content tools, matters more for the specific use case.
Is Moz Pro a good budget alternative to Semrush
Moz Pro is generally the most approachable of the major SEO platforms, starting from around $49 a month, the lowest entry price among the full-suite alternatives compared here, though it has fallen behind Semrush and Ahrefs on some more advanced feature sets in recent years.
Moz has been one of the longest-established names in SEO software, and its Domain Authority and Page Authority metrics remain widely recognised and understood across the industry, even by people outside core SEO roles. Its interface and educational resources are generally considered the most beginner-friendly of the platforms compared here, which matters for a small team or a single in-house marketer without a dedicated SEO specialist. At around $49 a month for its entry-level plan, Moz Pro undercuts both Semrush and Ahrefs' comparable tiers substantially. The trade-off, reflected consistently in independent platform comparisons, is that Moz's keyword database and site audit depth have not kept pace with Semrush and Ahrefs' more recent feature development, making it a stronger fit for straightforward SEO monitoring than for advanced competitive or technical analysis.
How do SE Ranking and Mangools compare on pricing flexibility
SE Ranking and Mangools both price around the volume of keywords tracked rather than a single flat tier, which can make them more cost-effective than Semrush for a business tracking a smaller, focused keyword set rather than needing broad all-in-one coverage.
Where Semrush and Ahrefs both use largely fixed-tier pricing structures, SE Ranking's pricing scales more directly with the number of keywords being tracked, which suits a business or agency that wants to pay closer to what it actually uses rather than a flat monthly rate regardless of usage. SE Ranking also includes daily rank tracking and AI search visibility tools on most of its plans without the additional charges that apply on some rival platforms for the same functionality. Mangools takes a similar volume-based approach at a generally lower price point again, positioning itself for freelancers and small businesses rather than agencies managing multiple large client accounts. Both are worth evaluating specifically against a business's actual keyword tracking needs rather than assuming a full Semrush-equivalent feature set is required.
Are free tools like Ubersuggest a viable alternative
Free and low-cost tools such as Ubersuggest, from around $12 a month, can cover basic keyword research and simple site audit needs, but generally lack the backlink depth, historical data range and technical crawling capability of Semrush, Ahrefs or Moz for more demanding SEO work.
For a very small business or an individual just starting to work on SEO, a budget tool like Ubersuggest can provide a genuinely useful entry point at a fraction of the cost of the major platforms, covering basic keyword volume data, simple competitor overviews and introductory site audit checks. The limitation becomes apparent once the work moves beyond basic keyword lookup into competitive backlink analysis, large-scale technical site audits, or tracking brand visibility within AI-generated search results, areas where the depth and accuracy of Semrush and Ahrefs in particular remain difficult for lower-cost tools to match. For content and editorial research specifically, Kael Tripton uses Semrush as its own primary research tool, reflecting this trade-off between breadth of data and cost at the publisher end of the market.
How should a business choose between these platforms
The right choice depends on whether the priority is backlink depth (Ahrefs), all-in-one breadth across SEO, paid search and content (Semrush), ease of use for a smaller team (Moz), or cost-efficient scaling with a focused keyword set (SE Ranking or Mangools).
Rather than treating this as a single best-of ranking, the more useful comparison is against the specific job the software needs to do. An agency managing multiple client backlink profiles is likely to get more value from Ahrefs' larger index. A single in-house marketer or small business wanting one platform that also covers paid search reporting and content planning alongside core SEO is more likely to find Semrush's breadth worth the higher entry price. A team newer to SEO, or one prioritising ease of use over depth, may be better served starting with Moz Pro's gentler learning curve. And a business tracking a narrower, well-defined set of keywords rather than needing broad competitive intelligence may find SE Ranking or Mangools' usage-based pricing the most cost-efficient route. Most of these platforms offer a free trial or a limited free tier, which is the most reliable way to test fit against a specific website before committing to an annual contract. Contract length is worth checking alongside monthly price on every platform compared here, since several providers offer a meaningfully lower rate on an annual commitment than on a monthly rolling plan, which matters for a business still evaluating whether a given tool will remain the right fit over a full year.

What is the cheapest full SEO platform
Moz Pro is generally the lowest-priced of the major full-suite SEO platforms, starting from around $49 a month, though SE Ranking and Mangools can work out cheaper still for a business tracking a smaller, focused set of keywords rather than needing broad coverage.

Can a free tool replace Semrush for SEO research

Which SEO tool includes AI search visibility tracking
Semrush and SE Ranking both include AI search visibility tools on their standard plans, tracking brand mentions within AI-generated search results, an area Ahrefs does not natively cover in the same way as of 2026.
