Semrush has the deepest keyword, backlink and rank-tracking databases in SEO, and it is superb at research. But it hands you a report and leaves the work to you. Machinence's SEO Optimiser scores any page 0 to 100, suggests keywords with difficulty and intent, and fixes the issues in one click, rewriting your content, meta tags and more. And it is one of 22 tools that run your whole business, for a flat £99 a month, in pounds.
Semrush is genuinely world-class at research: the deepest keyword, backlink and rank-tracking databases anywhere. But it reports problems, it doesn't fix them, so you or an agency still do the hands-on work. Machinence's SEO Optimiser instead scores your page, flags every issue by impact, and applies the fix in one click. Semrush also builds no website or store, has no CRM or finance, and the bill climbs with per-seat fees and paid add-ons.
Semrush's content tools need the Guru tier, and you still have no website, CRM or finance. Add those and it stacks up.
Machinence is one platform: 22 AI tools with 820+ features to run your business, built so your website, marketing, finance, support and data all work as a single unit, not a pile of disconnected apps.
This is the Machinence ecosystem. Every Machinence tool shares the same data in real time, so a sale updates your CRM, your books, your analytics and your email list at once, with no plugins, no integrations and no developer.

Machinence's SEO Optimiser scores any page, store or blog 0 to 100, suggests keywords with difficulty and search intent, runs a full technical audit (Core Web Vitals, schema, mobile), and then fixes issues in one click, rewriting your content and meta tags automatically. Semrush goes deeper on raw research, its keyword database, backlink index and daily rank tracking are the deepest around, but it reports problems rather than fixing them. For an owner who wants to rank without an agency, Machinence closes the loop from insight to done.
Honestly, on research depth: a 25-billion-keyword database, the deepest backlink analysis, and granular daily rank tracking across locations and devices. Machinence doesn't offer a backlink index or that scale of SERP rank tracking. If you're an SEO specialist or agency living in that data, Semrush leads.
Yes, that's the core difference. Fix All Issues rewrites your content, meta titles, descriptions, image alt text and internal links in one click, then you publish. No copying recommendations into your site by hand, and no waiting weeks for an agency report.
Semrush is SEO-only and priced from $139.95/mo in USD, with per-seat fees and add-ons for local SEO, social and ads. Machinence is a flat £99 in pounds for 22 tools, the SEO Optimiser plus the whole business, with no per-seat penalty.
