Forget about those sites:
- Find a niche market (250 searches per day minimum and competition of results smaller than 1,000,000)
- Buy a domain name (keyword rich)
- Develop a W3C website
- Create 20 pages of unique and relevant content (keyword rich)
- Do a slow link campaign (1-3 new links per week)
- keep adding new pages every single week
- keep adding links in a slow manner
Basically, do the best and most interesting site for your niche visitors.
In some months, 6-9, you’ll see traffic coming in from serp’s. First 10 uniques per day, than 30 per day and so on… Only then place Adsense ads.
Keep focusing yourself on same site and dominate the niche to get all daily searches + longtail keywords (this is for lesson #2)
Good luck. And yeah, it works for me.
