Semrush vs Siteimprove SEO: which SEO tool fits your team?

Semrush

Content optimization is included in Pro+ and the platform documents briefs and draft scoring, but publishing is not core SEO-plan execution.

Pro+ includes content optimization; Semrush describes briefs and draft scoring: https://www.semrush.com/pricing/seo-ai-search/; https://www.semrush.com/kb/995-what-is-semrush

Siteimprove SEO

Real-time optimization, AI scoring, briefs, outlines, internal links, and persona guidance support execution, with human writing still implied.

The content optimization page describes real-time feedback, an AI content score, and a pre-publish checklist: https://www.siteimprove.com/platform/content-strategy/content-optimization-software/

Semrush

Competitor domains, traffic sources, top pages, keyword gaps, and backlink context are supported.

The official feature list describes domain strategy, traffic sources, top pages, keyword gaps, and backlinks: https://www.semrush.com/kb/995-what-is-semrush

Siteimprove SEO

Uses competitor, SERP, performance, keyword, and content-universe context; internal-company-data grounding is not specifically documented.

Content Blueprint AI is described as mapping the content universe and contextualizing competitive gaps with live performance data: https://www.siteimprove.com/platform/content-strategy/content-strategy-planning-platform/

Semrush

Current plans track AI prompts, AI brand performance, sentiment, and visibility across major AI systems.

Pricing lists AI-search tracking and AI Visibility limits; the product page names ChatGPT, Gemini, and Perplexity: https://www.semrush.com/pricing/seo-ai-search/; https://www.semrush.com/kb/995-what-is-semrush

Siteimprove SEO

AI-search/AEO visibility is an explicit product goal, but detailed GEO measurement and optimization mechanics are limited on public pages.

The official SEO page explicitly says the platform targets visibility across search engines, LLMs, and AI search: https://www.siteimprove.com/platform/seo/

Semrush

Multi-location and device tracking is explicitly available in Pro+.

Pro+ includes multi-location/device tracking: https://www.semrush.com/pricing/seo-ai-search/

Siteimprove SEO

The product is positioned for AI-era discoverability and content authority, but lacks public detail on citation tracking, prompt testing, or engine coverage.

Siteimprove frames SEO as visibility for humans and AI and says AI-powered insights turn into search performance: https://www.siteimprove.com/platform/seo/

Semrush

Site Audit and on-page/technical SEO workflows are core SEO Toolkit capabilities.

The Toolkit lists Site Audit, On Page SEO Checker, and technical SEO auditing: https://www.semrush.com/kb/806-seo-toolkit

Siteimprove SEO

Comprehensive audits, prioritization, historical tracking, broken-link and site-health workflows are directly documented.

The technical SEO page says it automates comprehensive site audits and prioritizes critical errors; its FAQ also names historical tracking and collaboration: https://www.siteimprove.com/platform/seo/technical-seo-auditing-tools/

Semrush

Official pages support content optimization and describe content workflows, but do not establish a full native publishing workflow for the core product.

The core pricing page only explicitly lists content optimization at Pro+; the official product description discusses content workflows without establishing core CMS publishing: https://www.semrush.com/pricing/seo-ai-search/; https://www.semrush.com/kb/995-what-is-semrush

Siteimprove SEO

Pre-publish feedback and CMS integrations support workflow; autonomous publishing is not claimed.

Siteimprove says optimization feedback is delivered during writing before publish and that CMS plugins support work in existing CMSs: https://www.siteimprove.com/platform/content-strategy/content-optimization-software/

Semrush

Daily keyword rank tracking, AI visibility reporting, sentiment monitoring, and SEO Share of Voice are supported.

SEO, Pro+, and Advanced plan features include Position Tracking, AI reports, sentiment, and Share of Voice: https://www.semrush.com/pricing/seo-ai-search/

Siteimprove SEO

Automated rankings, dashboards, reports, paid/organic comparison, and business-impact analytics are central strengths.

The SEO analytics page documents automated keyword monitoring, customizable dashboards, shareable reports, and paid/organic comparison: https://www.siteimprove.com/platform/seo/seo-analytics-tool/

Semrush

Team/agency positioning and additional-user support exist, but advanced collaboration is primarily enterprise-oriented.

Semrush describes plans for teams/agencies and additional-user pricing, while enterprise adds team governance: https://www.semrush.com/kb/1011-subscriptions

Siteimprove SEO

Shareable reporting, cross-functional content planning, and collaboration features are documented; granular permissions are not public.

Siteimprove describes shareable reports and a single source of truth for planned content and cross-functional teams: https://www.siteimprove.com/platform/content-strategy/content-strategy-planning-platform/

Semrush

A free tier and trials make evaluation accessible, but paid plans start at a high monthly price.

Free is $0 and seven-day trials are documented; SEO is $139 monthly: https://www.semrush.com/pricing/seo-ai-search/; https://www.semrush.com/kb/1011-subscriptions

Siteimprove SEO

The product is clearly enterprise-oriented but lacks public prices, free trials, or transparent limits.

The official conversion page asks for a personalized walkthrough rather than publishing plans or prices: https://www.siteimprove.com/demo-request/

Semrush

A limited free account exists with one demo project and daily report limits.

The official pricing page states the Free plan limits: https://www.semrush.com/pricing/seo-ai-search/

Siteimprove SEO

A separate free SEO Website Checker exists, but the core Siteimprove SEO product pages do not document free access to the enterprise platform.

Siteimprove's official toolkit describes a free checker that scans for 14 SEO errors: https://www.siteimprove.com/toolkit/seo-checker/

Semrush

Official company materials provide meaningful adoption figures, though the clearest paying-customer figure is from 2023.

Company timeline reports 100,000 paying customers and 1,000,000 free registered active users in 2023: https://www.semrush.com/company/

Siteimprove SEO

First-party marketing materials indicate broad enterprise adoption, including a numeric claim of 2,000+ global companies.

The official demo page says Siteimprove is trusted by 2,000+ global companies: https://www.siteimprove.com/demo-request/

Semrush

MCP access and API data integration provide machine-access paths, but the evidence does not establish a broadly autonomous SEO agent.

Starter includes MCP access and Advanced includes API data integration: https://www.semrush.com/pricing/seo-ai-search/

Siteimprove SEO

Siteimprove.ai explicitly uses agents and describes agentic content intelligence, but the SEO pages provide limited detail about autonomous SEO-agent actions.

The platform page says AI agents work across accessibility, analytics, SEO/AEO, and content strategy: https://www.siteimprove.com/platform/

Semrush

AI-powered recommendations and AI visibility features assist workflows, but human execution remains necessary.

Semrush describes AI-powered recommendations and AI visibility features, while the SEO Toolkit presents actionable insights rather than autonomous execution: https://www.semrush.com/kb/1011-subscriptions; https://www.semrush.com/kb/806-seo-toolkit

Siteimprove SEO

Automation is strong for audits, monitoring, reporting, and recommendations, but public evidence emphasizes human-guided optimization rather than autonomous end-to-end execution.

The product describes automated audits and keyword tracking while presenting feedback and checklists for teams to act on: https://www.siteimprove.com/platform/seo/technical-seo-auditing-tools/
