I have been using, for a while now, with this cool technique.
It helps you drive quality laser targeted traffic for FREE.
Read and follow the following steps:
1. Set an account in Google Alert --> Google Alerts
2. Choose your niche keywords, laser targeted
3. Set your alert as comprehensive and as it happens
4. When you receive an alert, use it to post your VALUABLE comments, signing with your links
If you are going to use MANY alerts, perhaps you should consider opening a dedicated Google email...(per niche)
This is so cool you are going to enjoy it! :rolleyes:
