hello,
I having some problems with some of my webpages.
At beging its was ranking well, but two months ago I lost all ranking. The
website isnt banned, but it is at end of results (like numer 950)

The website its very dynamic, at first month (with some keywords at top 10
searches) the database was with 1000 records, that makes like 3*1000 pages.

Since I got traffic, I make the database bigger to 100000 records, which
translates to 100000 webpages. So this could be found by google as spam? The
data is being feeded by bots and externals APIs

Also, I had a bug, which in most pages I got an invalid link that was
pointing to an empty search result, almost causing an "infinite" crawl (not
real infinite) but the website turns to hace like 10000000 pages!

And finally after first month I start to do some SEO optimizations, and
around month two I lost almost all traffic.

Now I removed the bug, also resubmit for recosderation (four weeks ago).

I really dont know What a can do. rollback to the webpage of the first
month?

If anyone could check my web to give any ideas please ask me so i give the
url.
Could I sent it to here?

I really dont know how to fix this problems

Thanks!
