5. Competitor Ranked During the first 7 Days
If you ever see a website (in your niche) that is
1. ranked on the first 1 of Google
2. created during the last 7 days
... don't even miss that chance - write about the same topic.
Usually that kind of post is about a last update, I mean there certainly is a reason why this person ranked so fast. He went to the top surpassing old well-ranked posts.
You will rank too with a similar topic and similar keyword.
One disadvantage, of this method is that you can't find websites like this often, except by chance (or at least I don't know a way to find the latest well-ranked posts).
I will continue researching this topic and if I find a way to find latest ranked websites I will update this tutorial, but certainly the potential is there if you know how to use this factor to get ranked.
