and huge sorry for my english it's not my native language thanks

Well if you have a review blog i recommend meathead1234's google alerts method wich you can find here : http://www.blackhatworld.com/blackhat-seo/making-money/359445-easy-100-day-perfect-noobs.html

As far as seo goes check out the seo section and start from there.When in doubt just ask questions

i am already doing that but not many g alerts showing in my inbox i've set it 3 days ago only received 1 yet though i will be glad if you answer the other question in my thread thanks
