: Discrepancy in reporting 500 internal errors between Google Webmaster Tools (Search Console) and Moz Pro Google Webmaster Tools (Search Console) has found 27 500 internal errors within my client's

@Eichhorn148

Internal server errors can have multiple causes:


Code syntax errors that happen whenever you hit a particular page
Problems parsing user data that only happen for a specific user
Intermittent problems caused by something like the database going down


It is not surprising that different crawling bots find different numbers of 500 errors. You may have some 500 errors that always keep certain pages from loading, but many are going to come and go, or only effect a specific crawler.

Your server logs are usually a better source for finding these errors than the crawl reports from Google and Moz. Your server logs will also show the ones that are effecting actual users.

I routinely monitor my site for 500 errors using the logs and fix them as they come up.
