What you learn about a competitor
Public pages only. SEOSage does not show a competitor's traffic or backlinks, because that needs a paid data source.
- New pages: it compares their sitemap with the last look and lists new pages, and checks again about once a week while the app is open
- Pages found by links: pages that are linked but in no sitemap are listed too
- Topics they cover that you do not: each competitor page that none of your pages covers, named by its own heading
- Plan it: turn an idea into a to-do on the Dashboard under Content to write, then mark it Written
- Export CSV and Copy report: the scorecard, ideas and new pages, ready to paste into an email
What is SEO competitor analysis?
SEO competitor analysis is the process of studying how your competitors' websites are built, what content they publish, and how they perform in search, so you can identify gaps and opportunities in your own SEO strategy. It is not about copying competitors — it is about understanding the landscape and finding where you can do better.
Technical SEO competitor analysis is a specific subset that compares your site's technical foundations against competitors: page count, title and description quality, structured data use, site speed, HTTPS, internal links, and image alt text. This kind of analysis is fast to run because it only uses public information and does not require access to a competitor's Google Analytics or Search Console.
What you can learn from a competitor without paid tools
- How many pages they have indexed compared to you
- Whether they use structured data (which gives them rich results in search)
- Which topics they publish on that you have not covered yet
- Their site speed on mobile and desktop — a ranking factor
- How much internal linking they do per page
What requires a paid data source
- Organic traffic estimates — only tools with panel data (Ahrefs, Semrush) can estimate this
- Backlink counts and referring domains — also needs a paid link database
- Keyword rankings for their pages — needs a rank tracker
- Historical traffic trends — not visible without historical index data
SEOSage is a desktop SEO competitor analysis tool for Mac and Windows. You add up to five competitors per site, press Refresh all, and SEOSage reads each competitor's sitemap, a sample of their pages, and the links on their home and blog pages — all from your own computer, following each site's robots.txt. The result is a side-by-side scorecard, a list of topics they cover that you do not, and a list of new pages they published since the last check. Because the data is gathered by a local crawler rather than a third-party database, the numbers are based on the actual public pages of each site, not on a panel estimate.
Questions about competitor analysis
Can Claude read my competitors?
Yes, once Claude is connected. It can read the competitors you track on a site's Competitors page, how big and fast they are, their newest pages, and the topics they cover that your site does not.
What is an SEO competitor analysis tool?
It is a tool that measures your competitors' websites and compares them with yours. SEOSage compares the pages themselves: how they are built, how fast they load, what they publish and which topics they cover.
How many competitors can I track?
Up to five for each site. You can add another one while a check is running; it waits in line and runs next.
Does it show competitor traffic or backlinks?
No. SEOSage reads public pages only. Traffic and backlink numbers need a paid data source, which SEOSage does not use today.
Is it polite to the competitor's website?
Yes. It reads about three to five pages a second, follows the site's robots.txt and stops if the site starts refusing it.
How does it find new pages?
It compares the competitor's sitemap with the last time it looked, and also reads the links on their home page and blog pages. The first check only remembers what is there, so there is no false alarm.
Can I share the results?
Yes. Export a CSV, copy the report as text, or export just the content ideas.
