I ran into the same thing! My site still isnt indexed and I would REALLY like to not change the URL (its a shop and the url is printed on stuff) - redirects are my last resort.
But basically what happened: In august 2025 we finished the first working version of our shop. I wanted to accelerate indexing after some weeks because only ~50 of our pages were indexed and submitted the sitemap and everything got de-indexed within days. I thought for the longest time that its content quality because we sell niche trading cards and the descriptions are all one liners i made in Excel. ("This is $cardname from $set for your collection or deck!"). And because its single trading cards we have 7000+ products that are very similiar. (We did do all product images ourselves I thought google would like this but alas).
But later we added binders, whole sets and took a lot of care with their product data. The frontpage also got a massive overhaul - no shot. Not one page in index. We still get traffic from marketplaces and our older non-shop site. The shop itself lives on a subdomain (shop.myoldsite.com). The normal site also has a sitemap but that one was submitted 2022. I later rewrote how my sitemaps were generated and deleted the old ones in search console hoping this would help. It did not. (The old sitemap was generated by the shop system and was very large. Some forums mentioned that its better to create a chunked sitemap so I made a script that creates lists with 1000 products at a time as well as an index for them.)
Later observations are:
- Both sitemaps i deleted in GSC are still getting crawled and are STILL THERE. You cant see them in the overview but if you have the old links they still appear as normal.
- We eventually started submitting product data to google merchant center as well. It works 100% fine and our products are getting found and bought. The clicks still even show up in search console!!!! So I have a shop with 0 indexed pages in GSC that gets clicks every day. WTHeck?
So like... I dont even know anymore. Maybe we also have to restart like the person in the blog did and move the shop to a new domain and NEVER give google a sitemap. If I really go that route I will probably delete the cronjob that creates the sitemap in case google finds it by itself. But also like what the heck? I have worked in a web agency for 5 years and created a new webpage about every 2-8 weeks so i roughly launached about 50-70 webpages and shops and i NEVER saw that happen. Is it an ai hallucinating? Is it anti spam gone too far? Is it a straight up bug that they dont see? Who knows. I dont
(Good article though and I hope maybe some other people chime in and googlers browsing HN see this stuff).
