Ever wondered what's helping your competitors get ahead? Competitor analysis tools let you explore where their traffic comes from, which pages perform best, what keywords they rank for, and how they reach their audience. It's a useful way to see what's working for others in your industry and where you might be falling behind.
Beyond SEO, you can compare content strategies, spot gaps in the market, look at advertising activity, and see how competitors perform over time. Whether you're checking out a new market or trying to improve your current results, these tools can help you figure out where to focus your efforts next.
SEO competitor analysis can mean very different things: finding domains that rank for the same queries, uncovering keyword gaps, studying the pages that attract organic traffic, or comparing backlink profiles. Some tools begin with a known rival; others help discover competitors you may not have considered. They're grouped by job, not ranked.

For multi-angle competitor research
#1 of 10 in Competitor Analysis
Semrush combines domain-level and keyword-level competitor research. Organic Rankings shows a rival's ranking keywords, pages, SERP features, and organic competitors, while Domain Overview and Keyword Gap add side-by-side context; teams can move from a broad domain comparison into the exact queries and pages behind a visibility difference without leaving the same research environment.
Page and backlink discovery
#2 of 10 in Competitor Analysis
Ahrefs Site Explorer is useful when competitor analysis starts from a domain or URL. Choose it when deciding whether a competitor wins through topic coverage, links, or both. It exposes organic keywords, top pages, backlinks, referring domains, and historical changes, letting teams trace both the search demand and link support behind competing content.
For SEO and PPC overlap
#3 of 10 in Competitor Analysis
SpyFu treats competitors as domains that share organic rankings or paid keywords, which can uncover rivals beyond the companies a team already knows. Its SEO and PPC research areas both include competitor views, making it useful when organic and paid search strategies overlap. Analysts can compare shared keywords and identify domains entering or leaving the competitive set.
Project-based competitor checks
#5 of 10 in Competitor Analysis
SE Ranking's competitor analysis tools let users investigate a rival's organic keywords, traffic estimates, ranking pages, and paid-search activity, then connect those findings with tracked projects. This is useful for agencies that want research to feed ongoing monitoring and stay current beyond a one-time snapshot; domain analysis can also surface competitors based on shared search visibility.
Quick SERP comparisons
#7 of 10 in Competitor Analysis
Mangools combines SERPChecker, KWFinder, and SiteProfiler for lighter competitor research. SERPChecker shows the pages competing for a target query, while SiteProfiler summarizes domain and backlink information and KWFinder provides keyword context. The workflow is useful when a marketer needs to inspect a specific SERP and the domains inside it without building a large competitive-intelligence project.
Start by finding out who you're really up against in search. It's often not the company you'd call your rival. It's whoever ranks for the queries you want. Enter your domain in Semrush or SE Ranking and you'll get a list of the sites that compete with you most often in the results.
Then put your site and a competitor's next to each other. Compare estimated organic traffic, how many keywords each site ranks for and which pages bring in most of the visits. Ahrefs shows this in its Top pages report, and Mangools gives a quicker snapshot in SiteProfiler. Traffic figures are estimates, so use them to compare sites inside one tool, not as real visit counts.
To track a competitor's rankings over time, add their domain to the rank tracking project you already run for your own keywords. Semrush and SE Ranking both let you do this. When a rival jumps ahead on a query, check whether they published a new page or picked up new backlinks.
Last, look for gaps. A keyword gap report lists queries a competitor ranks for that you don't, and a backlink gap report does the same for linking sites. If you also run paid search, SpyFu shows the keywords a rival bids on right next to the ones they rank for.

An SEO competitor is any domain competing for the same search demand, even if it sells a different product or is not a direct business rival. Search tools often discover competitors by measuring shared ranking keywords instead of relying on a manually entered list.
Look at the queries those pages rank for, the intent they satisfy, how much of the competitor's visibility they represent, their backlink support, and whether your site has an equivalent page. The goal is to identify repeatable gaps, not simply copy a page.
