Press Release SEO. More than 90 press released in prweb. How good for seo

[Modi]

One of a competition sites known to us has published 90 press releases of all upcoming car models with PRWEB, PR7, DA 97 in last 4 months. All with different anchor based keywords and links. The page authority too is very high in some of them around 70

Though they might have had spent a sum, does this really influence from SEO perspective. If yes, can 10 press releases with PR Newswire which has PR8 and DA as 95 can be good if we consider doing this with all unique anchor text & links

Right around the holiday season last year (2012), Google reps stated press release sites would not be worthwhile for SEO purposes alone. Meaning, they would discredit link equity passed from the major PR sites. Now, it's worth noting that Google will make these announcements before actually implementing, but it usually means it's here or coming soon.

You'd probably be reallocating PR-funds and resources into something more long-lasting, like content and linkable assets.

It depends if the actual press releases, lead to more brand exposure via the people the content gets in front of, is info about the site then published elsewhere as well?

If used purely for link building, the value of so many links from the same domain will be limited, with the resources much better spent on more variety.

My advice to clients, is to only use press releases, when the site has something genuinely potentially newsworthy to announce.

Tom, has a great point.  If you're just writing a press release to write a press release you're being spammy.  There's no point in that, however if you have relevant content that will get shared and liked then us, I would definitely recommend writing a press release then.

Yeah, turn around online and someone will tell you don't write a press release without being newsworthy. That's not a realistic deterrent.

You're going to be able to squeeze just as much link juice from Squidoo as you will from PRWeb or any of the other large PR distro companies. People will always publish mediocre sub-par releases for link value. Why? Because they see it as a short cut.

From what I've seen, you can still eek SEO value out of it. But, Tom is right. The only SEO-value I would consider to be long-term is external online pickups.. editorial mentions from sites outside of the normal distribution network. Don't count on PRweb.com link lasting or passing full value.. or any value for much longer.
