Keyword Cupid

Keyword Cupid, from Keyword Cupid 2026 LLC, is a keyword clustering and grouping tool. It takes a keyword list and sorts it into topic groups — the work that turns an export from a research tool into a plan for what pages a site should have.

Subscriptions come in four monthly tiers, running from $9.99 at Starter through $49.99 and $149.99 to $499.99 at Enterprise. Each carries two separate allowances. Monthly keyword credits run 500, 5,000, 20,000 and 80,000, and the vendor leaves no doubt what happens to them: whatever is unspent when the cycle turns over is gone. The maximum size of any one report runs 2,000, 20,000, 40,000 and 80,000 keywords.

Sitting beside the subscription is a second, quieter meter. Credits can be bought on demand at a per-keyword rate the tier fixes, falling from $0.020 at the entry tier to $0.006 at the top, and the vendor says these do not expire, in the same breath as saying the monthly ones do. Set each rate against what that tier's own subscription works out at per credit and they track it closely, matching it on the two cheapest plans and coming in slightly under it on the two dearest. So topping up is not a penalty, and the tier you sit on sets your marginal cost either way. The vendor adds that buying in bulk earns up to 20% off, applied across the whole order.

The limits behave differently, and being clear about which one binds you is the whole sizing decision. Credits are a budget across a month, and one you can extend by buying more; the report ceiling is a hard limit on a single run, and no purchase lifts it. Starter's 2,000-keyword ceiling is the tightest constraint on the ladder, and a research export for a site of any size can exceed it — no amount of monthly budget, bought or allotted, lets you cluster a 5,000-keyword list in one pass on that plan. From Freelancer upward the ceiling stops being what constrains a single-site project. Which is the practical rule: run out of credits and you can pay to continue; run into the report ceiling and you have to change plan.

Neither a free plan nor a trial appears, which makes the $9.99 tier the evaluation step. That sits alongside what two reviewers said about testing it cheaply — see the community section — because the two facts interact: the smallest plan is both the only way in and the one with the tightest report ceiling.
