Most SEO competitor research produces a very long keyword list and not much else. You pull the gap report, see that a competitor ranks for 3,000 terms you don’t, and the spreadsheet gets filed. The number is just too big to act on.

I’ve run this process dozens of times with clients. The problem isn’t the data. It’s that most analyses don’t start with a revenue question. They start with a tool, and the output reflects that.

A real competitive SEO analysis isn’t about cataloging everything your competitors rank for. It’s about finding the handful of gaps that, if closed, would send more qualified traffic your way. Most of those 3,000 keywords won’t do that. The work is finding the fifteen that will.

Your SEO competitors aren’t who you think

Before touching any tools, get the competitor list right. Your business competitors and your SEO competitors are often completely different groups.

A local law firm might be competing for informational search traffic with a legal resource site that doesn’t practice law at all. A SaaS company might be losing search visibility to a comparison site that reviews software without selling anything comparable. Neither is a business competitor, but both are occupying positions in search results that could be yours.

Take your fifteen most important target keywords and run them through Google or an SEO tool. Look at who appears consistently across those searches. Build your competitor list from actual search data rather than your assumptions about who competes with you for customers.

This step matters because everything that follows is only as useful as the sites you’re benchmarking against. Benchmarking against the wrong competitors produces the wrong opportunities.

Start with their top pages, not their keywords

Once you have the right competitors, look at their top pages by organic traffic before opening a keyword gap report.

Most SEO competitive analysis tools have a “top pages” view. In Ahrefs’ Site Explorer, it’s listed under “Top pages.” In Semrush, it’s under “Organic Research > Pages.” You’re not looking at raw traffic volume in isolation. You’re looking at which pages drive the most visits and whether those topics overlap with what you actually sell.

Pay attention to pages where they’re getting meaningful traffic but the content is thin or the backlinks behind the page are weak. A competitor ranking position four for a high-value term with a 700-word page that hasn’t been updated since 2022 is a better target than one they’ve clearly spent time and links building out. Those underbuilt, high-traffic pages are the ones worth noting before you run any keyword analysis.

How to do an SEO competitive analysis: the gap step

The keyword gap analysis gets a lot of attention. It works best as a third step, not a first one.

With their top pages mapped and a clear picture of where their traffic comes from, run the gap report. In Ahrefs, this is the Content Gap tool. In Semrush, it’s the Keyword Gap section. You’ll get a long list. Most of it won’t be worth pursuing.

Filter aggressively. Remove anything below a minimum monthly search volume. Remove terms with no purchase intent. Remove keywords where the keyword difficulty score is above what your current domain rating can realistically compete for.

What you’re trying to surface is a short list of terms where a competitor ranks with average content, the search intent is commercial, and you could build or improve a page to compete. A gap report of 2,000 terms usually narrows to fifteen to twenty real opportunities once you apply those filters. That’s not a failure of the analysis. That’s the point.

Where revenue opportunities actually are

Two places consistently produce the most actionable findings in a competitive SEO analysis.

The first is bottom-funnel keywords where a competitor holds a weak ranking. Terms like “best [product] for [use case]” or “[service] in [city]” attract people who are close to making a decision. If a competitor sits in positions six through nine for these terms with a thin, aging page, there’s room to move past them with something better. Search volume on these terms is often modest. Conversion rate is not.

The second is content categories a competitor has built out that you haven’t addressed at all. Service area pages, comparison pages, and commercial intent content like “how much does X cost” are consistently underbuilt across most sites, including the competition’s. These aren’t hard to produce and often rank well because the bar is low. If a competitor has ten location pages and you have none, that’s not an optimization problem. It’s a content existence problem.

The SEO competitive analysis tools that matter

For how to do an SEO competitive analysis at a practical level, the two tools I use most are Ahrefs and Semrush. They overlap significantly but each has areas where it’s stronger.

Ahrefs is better for backlink research and content gap analysis. The Site Explorer gives a clean view of a competitor’s traffic, top pages, and referring domains. If I want to understand what content is earning links and driving visibility for a competing site, Ahrefs is where I start.

Semrush is stronger for local visibility data and paid search insights. You can see which keywords competitors are actively bidding on through the Advertising Research section, which is a useful signal for commercial intent. If they’re spending money on a term, it usually converts.

Both are expensive. Ahrefs has a $29/month starter plan that covers enough to run a basic competitive analysis if budget is a real constraint.

Turning findings into actual decisions

The analysis is useless without a decision at the end of it.

Take the shortlisted opportunities and sort them by traffic potential, keyword difficulty relative to your current domain authority, and how close the search intent is to a purchase. Terms that score well on all three go to the top of the content calendar or become optimization priorities for pages you already have.

One thing that’s easy to miss: some of the best opportunities aren’t gaps at all. If a competitor is ranking page one for a term where you’re currently sitting on page two, that’s not a content gap. It’s a push. A targeted content update and a handful of relevant backlinks might be enough to move past them.

A useful competitive SEO analysis doesn’t produce a fifty-page report. It produces a list of ten to fifteen moves, each with a clear reason behind it. That’s what actually gets executed.
