A SpyFu keyword gap alternative for keeping tabs on rivals

If you keep an eye on competitors, the most useful report in SpyFu is often the keyword gap: the searches rivals win that you do not. A SpyFu keyword gap alternative should give you that list when you need it, without a subscription you open once a quarter. seogeoaeo.ai's Keyword Gap does this for 85 credits a run. Here is how it compares with SpyFu's own gap tools, and a routine for using it.

What SpyFu offers for gaps

SpyFu's home page describes two gap features:

• Multi-Competitor Keyword Tool: type in your domain and see the important keywords your competitors rank for and you do not. It compares you with several competitors at once.
• Competitors' keywords you don't already buy: the paid search version, showing the core keywords your top Google Ads competitors buy and you do not.

It pairs these with keyword ranking history and rank tracking, so you can follow a gap over time. SpyFu says its data spans 38 countries and more than 18 years. We could not load its pricing page in October 2026, so check spyfu.com for what these features cost.

What seogeoaeo.ai's Keyword Gap does

Keyword Gap takes your site, one competitor and a market. It lists the Google keywords that competitor ranks for on the first two pages where your site does not rank at all, and sorts them into blog topics and keywords worth bidding on, with search volume and difficulty for each.

What it leaves out, by its own description:

• keywords you both rank for where you sit lower
• keywords the competitor ranks for below position 20
• keywords outside the country you pick
• keywords the competitor bids on in Google Ads

It covers the whole domain, not one folder or page.

Side by side

The trade is clear. SpyFu shows more competitors in one view and adds paid gaps and tracking. seogeoaeo.ai gives you a focused organic list for one rival, at a known price, whenever you ask.

A quarterly gap routine

This is a routine for someone who watches a handful of rivals and wants to act on what they find.

1. Confirm who your rivals are in search (38 credits). Run Competitor Finder on your site. It lists sites that rank for the same keywords as yours and separates close competitors from big general sites, which you can usually ignore. Your search rivals are not always your sales rivals.

2. Run a gap per close rival (85 credits each). For three rivals that is 255 credits. Pick the market you sell in.

3. See what they rank for overall (35 credits each, optional). Competitor Keywords shows the rival's full ranking list, including keywords you share, which the gap report leaves out.

4. Check what they say in ads (15 credits each). Competitor Google Ads shows the ads pointing at their site and which have run longest. A topic they rank for and also advertise on is a strong signal.

5. Act and rerun next quarter. Turn the blog-topic keywords into content, and rerun the gap in three months to see what closed.

All five steps for three rivals come to 38 + 255 + 105 + 45 = 443 credits, which fits in the $29 plan with plenty left.

Automating it

Every plan includes MCP and REST. A scheduled script can call keyword-gap with your site, a competitor and a market, set maxCredits to 85 so it never pays more, and post the new keywords somewhere your team reads. An agent in Claude Code or Cursor can do the same on request.

When to stay with SpyFu

If you compare against five rivals at once every week, need the paid keyword gap, or want daily rank tracking on the keywords you close, SpyFu's tools are built for that and seogeoaeo.ai's are not. If you check a few rivals each quarter, the per-run gap report costs less and gives you a list you can act on.
