Welcome to the Q&A Forum

I've been working on my site for over 2 years and have some very good links and now have a PageRank 4. My site has fallen down from page 1 to page 4 for 'Web Design London' which may be due to not putting much work into link building in the last 6 months. The site is pretty well optimised onsite but there are less that 20 pages of content. With time constraints in place because I have to run the business, would it be better to increase the content, seek out more links or outsource the work. Ideally I would do both but money and time restrict this. If I was to outsource, do you have recommendations and rough prices? Thanks
