## Key takeaways

- Semrush's Keyword Gap compares up to five domains across organic, paid and Shopping keywords, inside Semrush paid plans from $139 a month.
- seogeoaeo.ai's Keyword Gap compares one rival per run, shows the missing set only, and costs 85 credits.
- Teams that compare several rivals weekly are better served by Semrush; occasional one-rival checks cost less per run.

The keyword gap Semrush report is the screenshot people post when they want to look busy: five domains, seven ways to slice the overlap, a chart of who ranks where. Then, often enough, nothing gets written for a month. This is a short, slightly dry look at that report next to a smaller tool that does one part of it per run, and which of the two most teams actually need.

## What Semrush's Keyword Gap does

Going by Semrush's own help page, a lot:

- Up to five sites compared side by side.
- Organic, paid or Google Shopping keywords, and you can mix types between sites.
- Desktop or mobile.
- Subfolders, subdomains and single URLs, on the Guru or Business toolkits.
- Seven views of the overlap: shared, missing, weak, strong, untapped, unique and all.

That is a proper instrument. Missing means every rival ranks and you do not. Untapped means at least one rival ranks and you do not. Weak means you rank, but behind all of them. If your job title includes the word "SEO" and you compare against several rivals each week, this is the tool, and it is the honest recommendation for that job.

It also lives inside a subscription. Semrush's SEO plan is $139 a month, or $117.33 a month on annual billing. Starter is $199 a month.

## What most teams do with it

Open it, pick one rival (the one the CEO keeps mentioning), click "missing," export, sort by volume, and paste the top of the list into a doc called "Q3 content ideas." That covers one comparison, one view and one export, on a monthly plan.

## The one-rival version

[seogeoaeo.ai](https://seogeoaeo.ai) sells that exact workflow as a single run. Its Keyword Gap tool takes:

- your site,
- one competitor,
- one of 20 countries.

It returns up to the 300 most searched terms the rival ranks for and you do not, keeping only the ones where the rival is in Google's top 20. Each line has estimated volume, difficulty, intent and cost per click. The report then does the sorting you would do in the spreadsheet: easiest terms flagged, informational searches pulled into a blog topics list with the rival's brand removed, terms worth bidding on listed with their cost per click, and the rival pages that collect the most gap terms named at the end.

Price: 85 credits a run. Plans start at $29 a month for 2,000 credits, so a quarterly check on one rival uses a small slice of the cheapest plan.

## Side by side

| | Semrush Keyword Gap | seogeoaeo.ai Keyword Gap |
| --- | --- | --- |
| Rivals per comparison | Up to five | One |
| Sets shown | Shared, missing, weak, strong, untapped, unique, all | Missing only |
| Keyword types | Organic, paid, Shopping | Organic |
| Sorted into blog topics and ad terms | Filters you set yourself | Built into the report |
| Entry price | $139 a month (SEO plan) | 85 credits, plans from $29 a month |
| Use from an AI agent | Semrush lists MCP access on Starter | REST and MCP on every plan |

## The honest trade-off

seogeoaeo.ai does not compute the weak set. It does not compare five sites at once, and it does not show paid keywords a rival bids on. If the data provider has no record of the two sites, the run is refunded; if both sites are compared and there is simply no gap, you still pay. For weak keywords, Google Search Console's Performance report gives your own measured positions at no cost, which is better data than any estimate anyway.

## The step neither tool does

Both reports end at a list. Whichever you use, three cuts decide whether the list turns into pages. First, delete searches for the rival's brand; you will not take their login page from them. Second, open a few results pages and drop terms whose results have nothing to do with what you sell, however big the volume. Third, search your own site for each topic that remains. If you already have a page on it, the term is weak rather than missing, and a second page would only compete with the first. What is left, grouped by the rival page that ranks, is your plan.

## So which one

If you live in gap reports, buy the suite. If you open one a quarter for one rival, paying a monthly subscription for an overlap chart is a choice. The smaller option is [one gap run on seogeoaeo.ai](https://seogeoaeo.ai/tools/keyword-gap), followed by the part no tool does for you: reading the rival's top page and writing something better than it.
