ContextBolt SEO vs Semrush

Semrush is not really an SEO tool. It is a marketing suite that contains an SEO tool, alongside PPC research, advertising intelligence, social scheduling and a content platform.

That is a genuinely good product if you use most of it. The question is whether you do, because you are paying for all of it either way. ContextBolt is the SEO half on its own, inside the agent you already write in, for $35.

Count the tabs you actually open

Most people I talk to bought Semrush for keyword research and competitor analysis, and open two tabs. The other toolkits are there, impressive, and untouched.

Semrush’s entry SEO plan is $139 a month. ContextBolt is $35, covers keyword and SERP research, competitors, backlinks, page audits and AI visibility, and connects your Search Console for free. Over a year that is $420 against $1,668.

If you also run ads and need competitive advertising data, that is Semrush’s job and I am not going to pretend otherwise. The SEO tabs, the ones most people bought it for, are the part ContextBolt covers at $35.

The $199 problem

Here is the bit that catches people pricing this up, and it is worth being precise about.

Semrush’s AI-search prompt tracking starts on Starter at $199, not the $139 entry plan. MCP access for a new account is the same story. The current docs list Semrush One Starter and Pro+, plus legacy Classic Pro and Guru, with 50,000 API units per renewal.

So if you want Semrush inside your agent and you want to know whether ChatGPT mentions you, the real number is $199 a month, not $139. Both of those are in ContextBolt’s $35.

Also worth knowing when you read older comparisons, Pro, Guru and Business are retired names. The entry tier is called SEO now.

Research that ends in an edit

The workflow difference matters more than the price one.

In Semrush you research, then export, then go and write the page somewhere else, and about half the research does not survive the trip. That is not a Semrush flaw, it is what happens whenever the tool and the work are in different windows.

ContextBolt runs inside Claude, Cursor or Codex. You ask what the page ranks for, what the top three results answer, whether the title is doing anything, and what ChatGPT says when someone asks the buying question. Then you ask the same conversation to draft the change, with all of it in context.

Every successful lookup saves to your SEO Board automatically, so a week later the evidence is still there and you are not paying to find it twice.

Where Semrush still fits

Scheduled rank tracking on 500 keywords daily, scheduled crawls across five sites, link building as a managed outreach workflow, and agency reporting in formats clients already accept. And the breadth, if you genuinely use it, with paid media, social and content under one login.

That is a monitoring and reporting job. The job this page is about is deciding what to change and changing it, and for that the research lands in the agent doing the work, with daily Search Console snapshots covering your own movement. If you run paid media as well, run both. If you do not, start here and see which Semrush tabs you still miss.

What $35 actually covers

1,000 credits a month. Different tools cost different amounts, so that is not 1,000 identical lookups. Site audits charge per page audited, capped at 50 per run. Your AI app bills you separately for its own usage.

The SEO tool pricing guide sets the units out across the market, since every vendor counts differently and that is where most comparisons quietly mislead.

Try it on one page

Take a page that gets impressions and no clicks. Connect Search Console, ask what it ranks for, look at who is above it, audit it, and get the agent to write the fix.

Twenty minutes, and you will know whether you need the suite. Try ContextBolt SEO free for 7 days with 100 credits. A card is required, and it becomes $35 a month unless you cancel before the trial ends. For the agent-specific version of this decision, read ContextBolt SEO vs Semrush MCP.
