I have acquired a new client that needs our help getting a lot of on site SEO work done. Most of this work will be tweaking meta tags, removing duplicate meta tags, fixing/adding image alt tags, improving internal link structure, and other on site work.
We also need some help with PPC advertising. Installing tracking codes, and managing campaigns.
I need an expert in these fields that I can trust to do this work for me on a weekly basis. This project should take a couple of months, I'd like to do this project a little at a time each week until we complete.
Please show me some examples of SEO work you have done in the past.
NOTE: This site uses oscommerce, so it would be helpful if you are very familiar with that.
