As many of us may get headache on how to do seo well, searching for the expertise advise on the internet for a while I find a really good place to start for your site seo is using other service, which means pay to seo.

why do so? as seo is a system project, so if you have one site, it is not worth or hard to make seo, while if you have tons of sites which most cases are the seo company will get business like.

that makes thing easier and with lower cost. for yourself, it is great to save a lot of time in seo and focus on your website construction your business, sales channel and etc.

a really good place to find someone work for you is sites like freelancer

http://www.freelancer.com this sites looks like with a good reputation and very first rank in google, I tried this site, first time you register and want to post a project, you need to pay $10, if you pay with paypal or other method there is a small payment fee charged.

of course they also offer a chance for new registrant post for free, which limited for reviewing first and can be only bidded by people who without history rate yet.

another site looks good is http://www.youhaveaproject.com/account/signup.php but not yet make a try, as I consider this is complete free service, while checking the existing projects, I find their actual project fee is higher than freelancer.com.

anyway, both are good choice I think.

at the same time I find a good site http://www.wlmarketing.com/ looks very good seo package offered, not sure how their work quality maybe try later,

first I would see how the freelancer work get it done for the website traffic first.
