Upgarded woocommerce 2 to 3 and saw a large drop in rank

[plahpoy]

Hi guys, I recently upgraded from woocommerce 2 to v3 and rankings have been plummeting. I have double checked all of the schema, markup, technical, speed, etc and it all seems to be the same. The on thing that I did find is that while there used to be about 400 images (products) there are now over 1500 images in the index as all of the thumbnails are not in the sitemap. Would / could this cause the issue? Can i remove all the thumbs from the sitemap? if so any suggestions on how (google returns very little to nothing regarding this). Should i alt text every thumbnail.....

Thanks in advance for any suggestions.

I would dig into the analytics some more and look for patterns... did you lose traffic to product pages or category pages or homepage? traffic from image search or web search? are there a lot more indexed urls? did robots.txt change to allow more pages to be crawled? did filter config change? canonicals?

H Olegi,

We lost traffic to all areas. Robots are the same, canonicals seem fine.

There are a lot more url's that seem to be the various sized thumbnail images.

Now we are suffering heavily from the March update.

Thanks,
