How to Do a Competition Analysis That Actually Drives SEO Strategy
Every SEO agency faces the same moment. A prospect wants proof that your approach works better than whatever their current vendor is doing. Or a client asks why a rival keeps ranking for terms that seem obvious. Without a structured answer, you end up guessing. And guessing is expensive.
Knowing how to do a competition analysis turns that moment into an opportunity. It gives you a repeatable process to surface what competitors are doing, what they are missing, and where your client can step in. Done right, it also becomes the backbone of a retainer proposal that feels like a no-brainer for the client.
Start with the Right Competitors
The first mistake most people make is defining competitors by industry alone. If you run an ecommerce store selling leather bags, your real competitors are not every other bag brand. They are the ones ranking on page one for the same commercial keywords your client targets. A landscaping company in Austin competes against other local landscapers, not a national directory. So before you pull any tool, sit down and list the domains that show up for your client's core terms. Use Google Search Console to see which queries already bring traffic, then cross-check those against the SERPs.
Once you have a shortlist of five to seven domains, you can move into the actual work. This is where the process of how to do a competition analysis starts to take shape, because you now have a concrete set of targets to reverse-engineer.
Collect the Raw Data
You need a combination of tools to get a full picture. No single platform gives you everything. SEMrush and Ahrefs both offer strong domain overviews, keyword lists, and backlink profiles. Moz provides a reliable domain authority metric that some clients still prefer. SE Ranking is a solid alternative if budget is tighter. For a quick snapshot of traffic estimates, Similarweb works well, especially when you want to compare multiple sites side by side. SpyFu can show you the exact keywords competitors bid on in paid search, which often reveals intent gaps in organic strategy.
Start with a domain vs. domain comparison in SEMrush or Ahrefs. Look at the overlap in organic keywords. That overlap is your battleground. But do not stop at the shared terms. The keywords where competitors rank and your client does not are often more valuable. That is the Keyword Gap analysis, a feature both SEMrush and Ahrefs handle well. Export the lists and sort by estimated traffic or keyword difficulty. You are looking for terms with decent volume that are not impossibly hard to win.
Evaluate Content and Structure
Raw data only gets you so far. You have to look at the actual pages. Open the competitor's top landing pages. Read the content. Is it thin? Does it answer the searcher's question completely, or does it leave room for a better resource? A Content Audit at this stage means reviewing the top five to ten pages from each competitor and noting what they cover, what format they use, and what they leave out. This is where Screaming Frog can help by crawling the competitor's site (if their robots.txt allows it) to map out their site structure and find pages that are not linked prominently. Sometimes the best opportunities come from pages the competitor buried.
PageSpeed Insights gives you another angle. A competitor with a slow site is a vulnerability. Check their mobile load time and core web vitals. If they score poorly, that is an opening you can highlight in a Retainer Proposal. Clients understand speed. They may not understand TF-IDF, but they know slow sites lose visitors.
Backlink Profiles and Authority
Backlinks remain one of the strongest ranking signals. Majestic offers a historic index that can show you when a competitor gained or lost links, which is useful for spotting campaigns or penalties. Ahrefs and SEMrush both have robust backlink tools. Look at the Competitor Backlinks report to see who links to them but not to your client. Those are outreach targets. But do not just chase the same links. Look for patterns. Are they getting links from resource pages, industry roundups, or guest posts? Replicating the pattern is more sustainable than chasing individual URLs.
Sometimes a competitor has a link from a site that seems irrelevant. Do not dismiss it. It might be a sponsored post or a directory link that passes value anyway. The Wayback Machine can help you see if that link was always there or if it appeared after a specific campaign. Historical context matters, especially when you are trying to explain to a client why a competitor jumped ahead.
Social Signals and Brand Interest
Organic search does not exist in a vacuum. BuzzSumo lets you see which content from a competitor gets the most shares and engagement. If a particular topic generates buzz, it is a signal that the market cares about it. You can then build a better piece of content around that same theme. Google Trends can show you whether interest in that topic is growing or fading over time. Pair that with keyword data, and you have a roadmap.
Ubersuggest is sometimes overlooked, but it gives a quick content ideas view based on what is already performing. It is not as deep as Ahrefs, but for a fast check on content gaps it works fine.
Synthesize and Prioritize
By now you have a pile of data. The hard part is turning it into a story. Group your findings into three buckets: quick wins, medium-term plays, and long-term builds. Quick wins might be keywords where the competitor's page is thin or their site is slow. Medium-term plays could be topics they cover well but where you can create a significantly better resource. Long-term builds are things like building topical authority on a broader subject cluster.
This is also the moment to think about the White Label Report. If you are an agency presenting findings to a client, a clean, branded report that shows the data without your logo all over it can make the difference between a one-time audit and a retained engagement. Clients want to see their name on the insight, not yours.
The entire process of how to do a competition analysis becomes more powerful when you can show the client exactly where they stand and exactly what the next steps are. It shifts the conversation from "we think we can help" to "here is the evidence, and here is the plan."
Keep It Ongoing
A single analysis is a snapshot. Competitors change their content, build new links, and shift their keyword focus. Set a quarterly cadence to re-run the core comparisons. Tools like SE Ranking and Similarweb make it easy to track changes over time without redoing the whole manual process each quarter. Google Search Console will also show you shifts in your own click-through rates, which can indicate when a competitor has made a move.
Knowing how to do a competition analysis well means treating it as a living process, not a one-off deliverable. The agencies that build this into their workflow are the ones that win retainers and keep them.
