Since Google's Panda 4.0 and the latest updates were introduced in the last few weeks, some news wires have been badly hit.
Some wire services may not have the profile and clout of others, however, PR Newswire, one of the bigger services, has hit back. It's announced new guidelines to raise the quality of the content in news releases. In addition to that, it's taking steps to identify and remove "low quality" news releases that are using "questionable SEO tactics" from its own site.
Clearly, when it hits the bottom line, the site needs to do something. Now, its less likely to accept any old story for cash.
Has Google Panda 4.0 meant the day of SEO news distribution hit an end?
