What would cause my structured data items to drop off?

[Tylerj]

I have about 20,000 items on my Magento Site. I used a plugin to add structured data. If I use the Webmaster Tools Structured Data Tester everything shows up perfect. There are no errors on any page that I have spot checked.

My total items increased to about 2500, but has now started dropping. The numbers have dropped to about 725 over the last few weeks. What can I check?

Hi Tyler,

Do you see any changes in specific Schemas?

Martijn.

[Tylerj]

Nope. I didn't touch anything at all, that is why it is throwing me off.

Hmm interesting, do you see any changes in your crawl stats or the number of indexed pages?

[Tylerj]

Crawl stats are improving if anything. The last few weeks our pages crawled per day increased and our total indexed pages has steadily been increasing.
