I assess marketing software through 10+ years of agency work, current product research, buyer needs, competing tools and total cost.
How this review was prepared
This review combines my relevant operating experience with Keysearch's current product, pricing and technical documentation. I checked the limits, buying path and alternatives against a small-agency workflow; vendor claims remain attributed where independent evidence is unavailable.

The Verdict
Is Keysearch right for you?
Keysearch earns its place when the SEO programme is intentionally small.
It provides core research and tracking without a large-suite cost, but the caps and lighter data depth appear quickly in a multi-client agency.
Test tracking capacity is tight for agencies against one representative project before committing.
Who It's For
Who Keysearch is for (and who it isn't)
✓ Best for
- +Solo publishers. Research a focused editorial calendar without paying for an enterprise data stack.
- +Small in-house SEO teams. Combine keyword discovery, lightweight audits and manageable rank tracking.
- +Freelancers with a few sites. Keep recurring research affordable while the client roster is small.

What You Can Do
What can Keysearch do?
Build a realistic topic shortlist
Compare difficulty and intent, then validate the final cluster against the live search results before briefing it.
Track only the pages that can change
Reserve the allowance for priority pages and commercial queries instead of importing every possible keyword.
Use forecasts as a second opinion
Compare projections with Search Console and conversion value before changing the publishing plan.
AI, API & MCP
AI, API and assistant workflows
Keysearch's API returns volume, CPC, and difficulty data for keywords already searched inside a user's account, but it can't originate new keyword research on its own.
AI agent workflow
Prioritizing an existing keyword list
An agent pulls a user's previously researched keywords through the API, including volume, CPC, PPC, and difficulty score, and ranks them into a prioritized list for a content calendar. It can target any of the 40-plus supported countries via the API's region parameter, but only for searches that have already run inside Keysearch.
Approval boundary: There are no write actions in this API, so the only real constraint is respecting the vendor's internal-use-only license, meaning the data shouldn't be resold or repackaged for third parties.
MCP
noneNo MCP server exists
There's no evidence of a Keysearch MCP server, official or community.
API
officialKey-based API limited to already-searched keywords
Keysearch's API is documented at keysearch.co/api/documentation and authenticates with a per-user API key passed as a query parameter rather than a bearer token. A list endpoint returns volume, CPC, PPC, and difficulty for keywords, and a difficulty endpoint adds top-10 SERP analysis, but the vendor states the API is for internal use only and does not run realtime searches, so new keywords have to be searched in the Keysearch app first. Rate limits and plan gates aren't published.
Keysearch API documentation →Pricing
How much does Keysearch cost?
The published entry plan starts at $24/mo. For this review's professional buyer, the practical starting point is $48/mo before users and add-ons. No free plan, but there’s a 7-day free trial.
| Plan | Monthly |
|---|---|
| Starter | $24/mo |
| ProPopular | $48/mo |
Starter is $24 monthly or $20 per month billed annually. Pro is $48 monthly or $40 annually, and raises tracked keywords from 80 to 200 while including Foresight.
Count tracked terms first
Starter fits one focused site; Pro is safer when several projects or more than 80 tracked keywords are involved.
Do not price it as an API platform
The documented endpoint is a narrow keyword-difficulty lookup rather than broad account automation.

Downsides
Limitations to consider before subscribing
Tracking capacity is tight for agencies
Test this Keysearch boundary before the tool becomes part of a client or team promise.
Research depth is lighter
Large competitive markets may justify a broader backlink and keyword database.
Confirm current Keysearch entitlements
Recheck Keysearch's plan comparison before rollout, especially any API, MCP, export or usage allowance.
My Recommendation
My recommendation: use Keysearch while the SEO workload stays focused
Shortlist Keysearch when one or two sites need affordable keyword research, audits and a deliberately limited rank tracker.
Choose SE Ranking or Ahrefs when the client roster, tracked keywords or competitive research regularly exceeds those limits.
What to check during the trial
- –Research one complete topic cluster.
- –Compare difficulty estimates with the live SERP.
- –Import the exact keywords the team would track.
- –Check whether the narrow API supports the intended use.
