It would be awesome if page where you offer service with submission form and contact information appear right away on Google when people type related key phrases. It seems impossible for many webmasters because of competition.

 Building deep links directly for your service pages could increase chance of appearance in top 10. Many webmasters think that it is hard and almost impossible to find places and webmasters who will agree to provide deep link.

 It is enough to have 10-20 backlinks for additional page to rank well for websites which already well promoted and rank well. To increase rankings for service pages you can build links from:

•  Signatures in related forums.
•  Your profile on social networks. Just add your service (deep link) page as your own website.
•  Article submission with deep link in signature and your info page.
•  Many directories provide deep link submission for sponsored and reciprocal submissions.
•  Deep directories for deep links. You can find deep directory list on Directory critic.
•  Link exchange. Good way to build links. If you don’t trust reciprocal links you can use 3-way link exchange.
•  Your own websites. Place links to your services on your own sites.
•  Social bookmarking sites (don’t submit in social media and news sites). Submit in sites where you allowed to bookmark pages for yourself without sharing with other members.
