The shop drops out of the index and search

[BridalBlooming]

For the second month, I have been observing how the number of visits to the store has decreased by 30-50 per day. The situation is critical. If in June-July there were 1,500 visits per day, now there are 500+. I can't  attaching a comparative schedule of advertising work. It is completely down bay by day. Despite the fact that the budget is set to the maximum, not only is it not used, but expenses are reduced daily. This is directly related to search queries and results. How can this problem be solved?

@BridalBlooming: That your ad budget is at maximum is almost irrelevant in this case. Even if your titles and tags, etc. are perfect, the results that search now returns may very well mean that your listings are not being shown to the right people.

How can this be fixed? There were good results and in a month there was a 3-fold drop. This is very strange.

Lots of shops are reporting the same thing.

How this situation may be resolved? should I contact support?

You might want to look at the things Etsy has changed recently, and the new image requirements: https://www.etsy.com/legal/policy/listing-image-requirements/253962679005 

Search ranking is changing to be more about images, customer service, shipping costs & times, and unique images. 
Images need to be to least 2000 px on all sides, and you can't use mockups for physical products you make yourself such as the cake toppers. (That last rule is new, and I don't think Etsy is enforcing it yet, but I would get changing those quickly. Only POD and digital products can use mockups)

Once a shop's quality score drops as yours apparently has, you will have to make significant efforts to raise it again. Until then, your ads won't show as often and your search ranking will be lower. 

I'd also take a look at your stats to see if the traffic sources have changed. You may have been featured somewhere that was bringing you extra traffic. 

I hope things pick up for you soon!
