Page count is how many crawlable URLs Crawlinx reached from the homepage within the crawl budget, following internal links only. It is a rough proxy for site size and internal-link reach: a thin count often means orphaned pages, a robots wall, or a JavaScript-rendered navigation the crawler could not follow.
Across 17 Gatsby sites the median page count is 50, with the middle half falling between 28 (25th percentile) and 50 (75th percentile). The full range runs from 13 to 50.
Because these sites share the Gatsby platform, they inherit the same defaults — its templating, URL structure, sitemap and meta handling — which is why they cluster. The remaining variance is down to theme, plugins and how each team configured them, so the most common issues below are the ones Gatsby does not solve out of the box and every Gatsby site owner should verify.
The single most common problem here is “Images without width/height (layout shift / CLS)”, present on 100% of the sample, followed by “Low text-to-HTML ratio” and “Missing <h1>”. The full ranking is in the table above — fix the top of that list first, since it is the fault most likely to be dragging this segment's median down.
