Big dip in errors last week?

[Becky_Converge]

Hi,

I have a client who has seen a big dip in their errors, warnings and notices - pretty much consistently across all - then they popped right back up the next week.

Is it possible it was a crawl error? What is the best approach to trouble shoot and find out why this happened? As far as they know, nothing major changed on their end.

Thanks!

Hello Becky, Abe here at Moz. Matt could be right about changes to the website causing the sudden dip. I have seen a drop like that take place several times when some minor changes have been made. Sometimes when pages are temporarily hidden from our crawler, we would fail to report any errors during that crawl. If you are seeing a discrepancy or something seems totally off, never hesitate to contact us at help@moz.com. We can always dig in and get our engineers involved to ensure it wouldn't be a bug or error on our part.

Did your client change there website or hosting at all when the dip occurred?

If the client hasn't made any changes to there website during that time period where there was a dip and a week prior (MOZ crawl is once a week on Wednesday). I'd say it would be a crawl error.
