Services include, and are not limited to: 
Search Engine Optimization (SEO) and Placement
The goal is to rank well in Search Engine Result Pages (SERPs) for search terms that are applicable to your business and Web Site, and that are also actively searched for a good amount. Much easier said than done, this balance (of keyword search volume, to relevency) is difficult to achieve. Search Engine Optimization requires many steps. Knowledge of search engines, unique overall web site strategies, and keyword placement tactics are all essential. Good placement in Search Engines through optimization has excellent long-term value, but can also takes time to achieve, and must be diligently monitored.
SEM Sponsored Advertising / Pay Per Click Management
Sponsored Advertising, also commonly referred to as Pay Per Click or Cost Per Click Advertising, has been becoming increasingly popular over more recent years. The main avenues for Sponsored Advertising are Google's AdWords program, and Microsoft adCenter, which has now taken over Yahoo!'s Search Marketing program (formerly Overture). Getting involved in these programs is not too difficult, though getting a good return in them is. Because changes to Campaigns are processed pretty quickly, advertiser competition can be quite challenging for the novice manager.
Well Managed Sponsored Advertising and properly setup Campaigns can offer many benefits for an advertiser. Ad appearance in search engines can begin as quickly as the Campaigns are setup. There are many features to take advantage of only beginning with strong budget control, region specific advertising (from local, to nationwide, and even international advertising), and Ad syndication on "Partner Sites" and "Content Networks" in addition to Search Engines.
Social Media Optimization
Social Media Optimization (SMO) or Social SEO is considered where appropriate for client goals, and shares some principles of the more traditional SEO/SEM efforts.
ProPresence Web Marketing has had a lot of success specifically with Facebook advertising optimizations and managements for over recent years.
