What is Semrush?
Semrush is a search visibility platform that pairs SEO research with AI search tracking. Its plans combine two toolkits in one subscription: the SEO Toolkit, for keyword research, competitor analysis, backlink analytics, Site Audit and daily Position Tracking, and the AI Visibility Toolkit, which shows how your brand appears in Google AI Overviews, AI Mode, ChatGPT, Gemini and Perplexity. Research data is the main draw: Semrush's stats page lists 28.9 billion keywords, 142 geo databases and 43 trillion backlinks. For content, the SEO Writing Assistant checks drafts for SEO, readability, originality and tone of voice, in Semrush or through Google Docs, WordPress and MS Word add-ons, and the separate Content Toolkit ($60 a month) adds topic ideas, SEO briefs, AI article generation and real-time optimization recommendations. Local, Social, Advertising, Traffic & Market and AI PR toolkits can be added on top.
What is Surfer SEO?
Surfer SEO, which its own site now calls Positive Surfer, is a content optimization platform from Poland, founded in 2017. Its center is the Content Editor: you pick a keyword and location, and Surfer builds guidelines from your "Organic Competitors", the pages ranking in Google's top 10 for that location plus the top-cited pages in AI answers. As you write, real-time metrics cover structure, word count, keywords and images, and a Content Score shows whether the draft is on track; Surfer says it analyzes more than 500 ranking factors. The editor adds Surfy (an AI writing assistant), Auto-Optimize, an Outline Builder, automatic internal linking, an AI Detector and Humanizer, a Plagiarism Checker and Surfer AI for full articles. Keyword Research and Topical Map help plan topics, Content Audit monitors published pages and flags ranking drops, and AI Tracker measures how AI assistants mention your brand. Surfer connects to Google Docs (through a Chrome extension), WordPress, Contentful, ChatGPT, Jasper and Zapier.

A Free plan with no credit card allows 10 reports a day and one project, and the SEO, Starter and Pro+ plans can be tried free for 7 days, with exports disabled during the trial. Refunds cover initial annual subscriptions within 7 days; month-to-month subscriptions are not refundable.
Surfer prices each plan per account, with team seats included. Billed yearly and charged up front, Discovery is $49, Standard $99, Pro $182 and Peace of Mind $299 a month; billed monthly they are $59, $119, $219 and $359. Enterprise is listed at $999 a month, and AI Search Analytics, a plan built for AI visibility tracking, is $82 a month billed yearly ($95 monthly). Surfer has no free plan: "Start for Free" opens a 7-day Pro trial that takes billing details at checkout and converts to the plan you picked unless you cancel.
What the entry plans buy. Semrush SEO covers 5 monitored websites, 500 keywords tracked daily, basic keyword research, Position Tracking, a Site Audit of up to 100,000 pages a month and 3,000 reports a day; Semrush notes that it lacks a dedicated AI prompt-tracking quota, which starts on Starter. Surfer Discovery covers 120 documents a year (10 a month on monthly billing), 10 tracked pages, the Content Score guidelines, Surfy and the Humanizer, for one seat; keyword research and the WordPress and Google Docs integrations start on Standard.
A worked example: a five-person content team. Surfer Pro includes five seats and 360 documents a year for $182 a month billed yearly ($2,184 up front) or $219 billed monthly. Semrush Pro+, the plan that lists content optimization, includes one user, so five people cost $299 + 4 × $80 = $619 a month on monthly billing. Running both costs $838 a month on monthly billing.
