How to see a competitor's keyword gap every quarter

If you already keep an eye on competitors' pricing pages, launches and press, their search rankings are the piece most people leave out. You can see competitors' keyword gap, the searches they win in Google where your site has no page, with one report. Run it on a schedule and you get something closer to a watch: a list of what they have started ranking for since you last looked. This guide sets up that routine.

Why a gap list works as a monitoring signal

A competitor's new page rarely gets announced. It shows up in search results first. When a rival starts ranking for a cluster of terms you have never targeted, that usually means one of three things: they published a new guide or tool, they moved into a segment of your market, or an older page of theirs finally gained ground. A gap report taken every quarter puts those shifts on one page.

The setup, once

1. Choose one or two search rivals. Not the company your sales team mentions most, but the site that keeps sitting above you for the searches that bring buyers. seogeoaeo.ai's Competitor Finder lists the 30 sites sharing the most Google keywords with yours (38 credits) and separates close rivals from big general sites, which helps when you are not sure.
2. Fix the country. Compare in the market where you sell, and keep it the same every quarter so the lists are comparable.
3. Decide where the results live. A shared sheet with one tab per quarter is enough.

The quarterly run

seogeoaeo.ai's Keyword Gap tool takes your site, one competitor and a country. It returns up to the 300 most searched keywords that competitor ranks for in Google's top 20 where you have no ranking, with estimated monthly searches, difficulty, intent and cost per click. It also lists the competitor pages that win the most of those keywords.

That last list is the monitoring part. Paste it into the new tab and compare it with last quarter's:

• A page that is new to the list is likely new content or a page that recently climbed.
• A page that moved up the list is collecting more of your missing searches than before.
• A page that dropped off may have lost rankings, or you may have closed the gap with your own page.

Each run costs 85 credits. Two rivals a quarter is 680 credits a year, well inside one month of the $29 Indie plan's 2,000 credits.

What to do with what you find

Most quarters the useful output is a short list:

• Two or three rival pages that now win a cluster of terms you care about. Each is a candidate brief.
• Terms that sit in the blog topics list the report builds, which keeps out searches for the rival's own name and anything above a difficulty of 50.
• Terms in the bidding list, with cost per click, if you run Google Ads and want to test a topic before writing for it.

Before briefing anything, check you do not already have a page on the topic. If you do, the keyword is not missing, it is weak, and the fix is to improve your page.

Blind spots to cover elsewhere

The tool covers one competitor per run and the missing set only. It does not show keywords where you both rank and you trail; your own Search Console Performance report gives measured positions for those. It does not show which keywords a competitor bids on in Google Ads. Volumes and difficulty are estimates, so compare them within a list rather than treating them as traffic forecasts.

It is also a snapshot tool, not a rank tracker. If you need daily position history for a fixed set of keywords, a suite with rank tracking, such as Semrush or Ahrefs, is the better fit for that job.

Charges to expect

The price shows before each run. If the data provider has no record of the pair of sites, the run is refunded. If it compares both sites and finds nothing you miss, it is still charged, and the report says so. For most teams watching a few rivals, a seogeoaeo.ai plan covers a year of quarterly checks with credits to spare for other checks.
