How fast to develop links to a new website?

Could a website lose rankings because I developed links too fast…?

Recently some of my websites lost rankings in Google. For example one of the site that had 2nd position in Google search results for a keyword searched over 10,000 times now is not even found in first 100 results.

The site had 2nd position for about 3 weeks and now is not even found in first 100 results for about 2 weeks.

Could this be because I got 100 links to this site in 5 just days and then stopped getting any new links? If so then how many links per week would you recommend to get to a new website just to play safe with Google?
