I had created some web2.0 sites, google also indexed those sites but those sites robots.txt are disallow, this mean Google will not give any credit on ranking ? I have seen in google, those sites meta description was written - A description of this site is not available due to the robot.txt file. I checked that file, it is written disallow. Can google still count those sites for the ranking purpose ?

I am creating private blog network. I am buying expired domain. How much domain authority score required to popular my domain. I mean some of the domain i seen have 10+ DA score and age is also 10+ years. Kindly advice.

So it's all depends on audience target. So you want to say, i have to go .com or major TLD because .ME is new and for only youngster ?

I am always listening about TLD. com. org .net but what about the .me domain. Can this will be effective in SEO. Can i able to beat down my competitors, if i choose .me . I also have a .com or other TLD option but if i am making my name than .me is for me but i need your suggestion for the seo purpose. Is there really domain affective in term of SEO.
