Dex Media issued a press release today announcing it has achieved a comfortable lead as the most-used IYP/local search site within Dex's 14-state home region, with a 32 percent share of directional media searches for the period, according to comScore. Dex came out ahead of Verizon SuperPages, Yahoo! (Local + Yellow Pages), Google Local and YellowPages.com. This certainly represents an achievement for Dex and an affirmation that its product is responsive to consumer needs. It also suggests Dex is doing an effective job of marketing its online directory. While Dex's success is praiseworthy, an incumbent directory publisher really should win in its home market if it is doing the right things. A failure to do so suggests an insufficient product, insufficient marketing or both. You can find Dex's announcement here.
