Hello guys, Im really newbie on SEO i have domain iphone8gb.net and im sure there are good amount of searches for keyword "Iphone 8GB" so what should i do now to get good position in Google search engine? Should i add my link to directories and get good backlinks or what should i do? I also added link in DP sigi will it make any difference?
Absolutely get as many back links as you can. And, yes, add your site in your signature wherever you can You are competing with all those other sites that have iphone 8gb in them. What will help make your site 'more important' than all those other site will be backlinks. Otherwise, in the search engine results, you'll be at the bottom of the pack
I would focus on backlinks. Try to find some sites to exchange links with you. There's a forum here for that. I've also had some success with submitting blog posts to various blog carnivals.
You will find plenty of help here on this forum but yes back links are very important also make sure your onsite SEO is up to scratch with meta tags etc and make sure you have links on your site with your keyphrases. try use articles and press realeases as well.
Focus on building backlinks, comment on related dofollow blogs with the anchor text as your name and swap links with similar blogs. You will have to be consistent with your link-building efforts since there's probably a lot of competition in your niche.
