Frase vs Semrush is not a comparison that gets discussed as often as it should be — partly because most SEO professionals would not consider them direct competitors, and partly because the price difference is so significant that many small business owners rule out Semrush before properly evaluating what it offers. But the comparison is exactly the one that small business owners researching AI SEO tools end up facing: Frase at £10 per month covers the content creation and optimisation workflow, while Semrush at £99 per month covers the full SEO landscape. Understanding which of those two coverage areas you actually need is what determines the right answer for your business.
The honest framing is that Frase and Semrush are built for different jobs. Frase is a content creation tool with SEO built in — it helps you produce well-optimised content more efficiently. Semrush is a comprehensive SEO intelligence platform — it helps you understand your entire search presence, your competitors, your technical issues, and your keyword opportunities across every channel. Most small businesses need Frase’s job done well. Fewer small businesses need Semrush’s job done, and those that do often need it more than they need Frase.

What Is Frase?
Frase is an AI-powered SEO content platform that focuses specifically on the content research, brief creation, and optimisation workflow. Enter a target keyword and Frase analyses the top twenty Google results to show exactly what your content needs to cover to compete — the headings, questions, topics, and word counts that the currently ranking pages share. The built-in AI writing tools then help you produce that content within the platform, while the real-time editor scores your article against the competing pages as you write. Frase is designed for content creators and small business owners who want to produce content that ranks without needing a background in SEO. See our full Frase review for the complete breakdown of features and limitations.
What Is Semrush?
Semrush is the most comprehensive SEO platform available — a full-suite tool that covers keyword research, competitor analysis, backlink monitoring, technical site auditing, local SEO, social media analytics, content marketing, and paid advertising intelligence in a single platform. It is the tool that professional SEO agencies use as their primary research and reporting platform, and it is used by marketing teams at businesses of all sizes to manage and improve their entire search presence. The AI features added in recent years include ContentShake AI for AI-assisted article writing, an AI-powered SEO Writing Assistant, and AI-generated content recommendations based on keyword data.
Frase vs Semrush: Head-to-Head
Price
Frase starts at £10 per month for the Solo plan. Semrush starts at £99 per month for the Pro plan — ten times the cost. For a small business owner with a limited marketing budget, this price difference is the most important factor in the comparison. Semrush’s price is justifiable for businesses where SEO is a primary growth channel and the tool is used extensively across keyword research, competitor monitoring, and technical auditing. For a small business that primarily needs to produce well-optimised blog posts and service pages, Frase covers the most important requirements at a fraction of the cost.
Verdict: Frase wins on price for small businesses by a significant margin.
Content Creation and Optimisation
This is Frase’s strongest area and where it genuinely competes with — and in some respects outperforms — Semrush despite the price difference. Frase’s content brief generation from SERP analysis is more tightly integrated with the writing workflow than Semrush’s SEO Writing Assistant, and the real-time content scoring is more accessible for non-specialists. Semrush’s ContentShake AI generates complete article drafts with SEO optimisation built in, which is useful for high-volume content production. For a small business whose primary need is producing well-optimised content efficiently, Frase is the stronger and more cost-effective tool. For a business that needs content creation as one component of a broader SEO programme, Semrush’s content tools within the wider platform become more attractive.
Verdict: Frase wins for content creation and optimisation at its price point. Semrush’s content tools are stronger at scale.
Keyword Research
Semrush wins this category comprehensively. The Semrush keyword research database is one of the largest available — covering search volumes, keyword difficulty scores, trend data, related keywords, and question-based keywords across multiple countries and languages. For a small business building its keyword strategy from scratch, Semrush’s keyword research capability is significantly more powerful than what Frase provides. Frase’s keyword data is useful for understanding the search context of a specific piece of content but is not sufficient for building a comprehensive keyword strategy. Businesses that need serious keyword research should use Semrush or a dedicated keyword research tool like Ahrefs alongside Frase for content optimisation.
Verdict: Semrush wins on keyword research — it’s not close.
Competitor Analysis
Semrush’s competitor analysis capabilities are one of its most distinctive and valuable features. You can see exactly which keywords your competitors rank for, which pages drive their most traffic, how their backlink profiles have grown over time, and where they are investing in paid advertising. For businesses in competitive markets where understanding competitor strategy is commercially important, this intelligence is genuinely valuable. Frase offers no meaningful competitor analysis beyond showing what competing pages cover for a specific keyword — it is a content tool, not a competitive intelligence tool.
Verdict: Semrush wins on competitor analysis. Frase does not compete in this category.
Technical SEO
Semrush includes a comprehensive technical site audit that identifies issues affecting search performance — crawl errors, page speed problems, missing meta descriptions, duplicate content, broken links, and dozens of other technical factors that can suppress rankings. For small businesses whose websites have accumulated technical debt or whose developers need guidance on SEO issues, the Semrush site audit is a genuinely useful tool. Frase has no technical SEO capabilities — it is focused entirely on content creation and optimisation. For small businesses using WordPress with RankMath or Yoast SEO, the most important technical SEO basics are covered without needing Semrush.
Verdict: Semrush wins on technical SEO. Frase has no technical SEO features.
Ease of Use
Frase is significantly easier to use than Semrush for small business owners without an SEO background. The workflow is clear, the interface is focused on content creation, and the output is immediately actionable. Semrush is a comprehensive professional platform with a steep learning curve — getting full value from it requires either existing SEO knowledge or significant time invested in learning the tool. Small business owners who try Semrush without SEO experience often find themselves overwhelmed by the volume of data and uncertain how to prioritise and act on what they are seeing.
Verdict: Frase wins significantly on ease of use for non-specialists.
Who Should Choose Frase
Frase is the right choice for small business owners and content creators who want to produce well-optimised content without an SEO background or a large budget. It is the right choice if content creation is your primary SEO activity — if your main need is producing blog posts, service pages, and landing pages that rank for target keywords. It is the right choice if you are just starting your SEO journey and need a tool that guides you through the process clearly and affordably. And it is the right choice if the £99 per month Semrush price point is difficult to justify at your current stage of business development. See our guide on how to use Frase for SEO for the step-by-step workflow that works best for small businesses.
Who Should Choose Semrush
Semrush is the right choice for businesses where SEO is a primary growth channel and the investment in comprehensive SEO intelligence is justified by the returns. It is the right choice if you need to understand your competitors’ search strategy in detail, build a comprehensive keyword plan from scratch, monitor your backlink profile, or audit your website for technical issues. It is the right choice for marketing agencies that manage SEO for multiple clients and need a single platform that covers all aspects of the discipline. And it is the right choice for businesses that have outgrown simpler tools and need the depth of analysis that only comprehensive SEO platforms provide.
Can You Use Both?
Some businesses use Semrush for keyword research and competitor analysis and Frase for content creation and optimisation — getting the best of both tools at a combined cost of approximately £110 per month. This combination is most justified for businesses that are serious about SEO as a growth channel and produce content at significant volume. For most small businesses just starting their SEO journey, Frase alone is the right starting point — and the money saved on Semrush is better invested in producing more content. See our Frase vs Surfer SEO comparison for another perspective on how Frase compares to premium SEO tools.
The Honest Verdict
For most small businesses, Frase is the right choice. It covers the content creation and optimisation workflow that produces Google rankings at a price point that is accessible from day one, with an interface that non-specialists can use effectively without significant investment in learning the tool. Semrush is a genuinely powerful platform that delivers real results for the businesses that use it correctly — but those businesses are agencies, content marketing teams, and established businesses with the budget, the expertise, and the content volume to extract full value from a comprehensive SEO platform.
Start with Frase. Spend six months producing well-researched, well-optimised content and building your search visibility. If you reach the point where you need keyword research at scale, comprehensive competitor analysis, or technical SEO auditing that Frase cannot provide — then Semrush is the right upgrade. For most small businesses, that point is further away than you expect.
