I have two sites I am promoting. Both with popular keyword phrases.
Site 1 is about 7 years old. When I started my current backlink building campaign, this site had about 30 backlinks gained over the last seven years.
Site 2 is 5 months old and had no backlinks when I got started.
I built 300+ backlinks for both sites over the last two months. The backlinks are all on the same pages, so that factor is identical.
Site 1 went from a google listing around 200 to 10 (first page, yea!).
Site 2 still hasn't broken into the first 1000 for it's key phrase.
I know that site 2 is in google. It will rank number 1 for an obscure keyword, but for the popular key phrase it just doesn't show up at all.
Is this the 'sandbox' effect? Site 1 is older, and had a few old backlinks, so it responded faster to the new backlinks I've built?
Do I just wait..... and how long... before I know if this is going to work for site 2?
Continuing to build links, but wanted to get feedback.
