How to Compare Your Website SEO With a Competitor, Side by Side
Run a free side-by-side SEO comparison with up to three competitors and turn the gaps into clear tasks.
Looking at a competitor's site and thinking "theirs just looks better" is not an action plan. A side-by-side comparison turns that feeling into specifics: their titles are clearer, their pages have more headings, their images all have alt text, their pages load faster. The free SeoSpidie competitor comparison tool crawls up to four websites and lines up their SEO signals so the gaps are obvious.

Step 1: Choose the right competitors
Pick sites that rank for the searches you care about, not just the biggest names in your industry. A local competitor on page one for "physiotherapist in Madurai" is a more useful comparison for a local clinic than a national hospital chain.
Step 2: Enter the sites
Enter your website and up to three competitors. The tool crawls each one and gathers the same set of signals for all of them, so you are comparing like with like.
Step 3: Read the category scores
The report groups results into categories โ such as on-page SEO, content, technical health and performance โ and scores each site. Start here to see where you are clearly ahead and where you trail. A large gap in one category usually points to the most valuable fixes.
Step 4: Drill into the on-page metrics
Look at the individual measurements behind each score. Typical differences worth acting on:
- Title and description โ missing, too long, too vague or duplicated.
- Headings โ a missing H1, or far fewer subheadings than competitors, which often means thinner, less structured content.
- Images โ missing alt text or oversized files.
- Links โ very few internal links compared with competitors.
- Structured data and social tags โ competitors using schema or Open Graph where you do not.
Step 5: Turn gaps into tasks
Write each gap as a specific task with the right tool:
- Rewrite titles and descriptions with the meta tag generator.
- Add structured data with the schema generator.
- Strengthen internal links with the internal link suggestions tool.
- Run a full site audit on your weakest page for a detailed fix list.
Step 6: Re-run after changes
Run the same comparison a month after your fixes. Your scores should improve where you worked. Remember that competitors change too, so a regular quarterly comparison keeps you honest.
What a comparison cannot tell you
Scores measure signals that are visible on the pages. They cannot measure brand reputation, the quality of a competitor's backlinks or how satisfied their visitors are. If a competitor scores lower but still outranks you, look at those factors โ and at whether their page matches search intent better than yours.
