Here it is straight from the man who spends all day long talking to Yellow Pages companies:
2008 will be the year of multi-channel expansion driven by yellow page companies. These co’s will start moving their advertisers across multiple media platforms – Ad sponsored DA, Mobile, IYP, Search, etc.
Call-tracking will unify platforms.
Yellow Pages headings will begin to move to Value Based Pricing in under-developed headings in an effort to grow ad base and content. (This is big)
SEO/SEM landing page optimization will become central to all local efforts. Platforms will be ubiquitous.
Verticalization will accelerate. Consumer and expert reviews will continue to grow in importance. Remember Matt I called it here first with my YellowPages 3.0 post!
Mobile will become the next search product and current advertisers will be pushed into the mobile experience.
