How to do competitor analysis in SEO

Start by identifying your actual competitors in search results, not just companies you perceive as competitors in your industry. Search for your target keywords and note which sites consistently appear in the top 10-20 results. These are your real SEO competitors because they're winning the visibility battle where it matters. Use tools like Semrush, Ahrefs, or Moz to pull their organic keywords, traffic estimates, and backlink profiles. You're looking for patterns: which keywords drive the most traffic, what content types rank best, and where their authority comes from. Check their technical setup too—site structure, page speed, mobile optimization, and schema markup. Tools can give you these insights quickly, but spend time actually looking at competitor pages to understand user intent and content depth. Note what makes their content comprehensive, how they structure it, and which pages get the most backlinks. This reveals what search engines and users actually value for those queries.

Next, analyze their backlink strategy because links remain one of the strongest ranking factors. Identify where their authority comes from—are they getting links from industry publications, directories, niche blogs, or university sites? Ahrefs and Semrush both show referring domains and link sources. Look for quick wins: resources or directories your competitors link from that you're missing. Check their brand mentions online too, particularly unlinked mentions, which represent conversion opportunities for your clients. You'll often find opportunities to earn similar links by creating better content or building relationships with those sources.

Finally, examine their content gaps and your advantages. Run their top keywords through their site search or use Semrush's content gap tool to see what they rank for that you don't. But also flip it: what keywords does your client rank for that competitors don't? These are defensible positions worth strengthening. Look at their content calendar if they publish regularly—timing, frequency, and topics all matter. Pay attention to what's working for them in organic search, but remember the goal isn't to copy their strategy. You're finding the competitive landscape, identifying where your client can win, and understanding what investment level is required to rank in that space.
