yeah to be honest the main sites that ive done nothing with and have done the best will grow naturaly for example my tottenham site, since ive been away i havent had time to work on the site, do any link building what so ever, but PR has gone up and serps has got better for some results although it got worse for one result but i think thats because other sites are pushing for that one more, So i wouldnt get too dishearted because ive done nothing, its just because its naturally growing, I think anyway
