Could you give me some suggestion about my E-com project(expired domain seems not work now)

hello friend,i set up one e-com website 5months ago,it is based on an expired domain,when the domain parked at sedo,it ranked 5th page in google about main money keyword without contents,
after i launched the website,the rank gone away,according to GSC,it have one impression at #101 rank about one month ago.
and this domain was used for blog (the same topic with now ecom-shop).
and when i using "site:domain.com" at google,it only show up 8 results,but At GSC,it shows i have over 14000pages indexed and still growing,but the GSC also show
over 30000pages Has been be excluded (because page is automatically redirected),i think these pages were post pages when it was a blog,
am i been penalized,what can i do now to get rank ASAP,thank you for any suggestion

I'm not knowledgeable enough on this topic to be able to help you, I'm only commenting so that others can see this (and hopefully chime in).

Personally, I wouldn't want to see 30k pages being excluded, something doesn't feel right to me, especially since you say they're redirects. Redirects to what??

And I'm not sure what you're asking, either. You want to know why you're not ranking / getting traffic despite of using an expired domain? Because that could be for many reasons (the domain is penalized which actually seems very possible if it has 30k redirects... or the domain is being sandboxed, or maybe your niche is tough, it could be many reasons, honestly).

Either wait for better replies, or hire someone to check your domain for penalties / possible SEO issues, that's where I would start. You can ask for help in this forum if you're willing to pay:

If you're not willing to pay... well, you'll have to do it yourself then .. Just check the domain in WBM yourself (this should not take you long), and look up tutorials on google / BHW on how to check expired domains for penalties...
