I am convinced a press release is very effective method of Social SEO. I recently tracked a press release for a stuffed hamburger maker named
Stufz. I chose this product due to the ease of tracking a unique name in addition to a love of stuffed sandwiches. The release was multi-media with embedded links on the brand terms.
I monitored Google results pages looking for brand mentions in blogs, tweets and just about any where else Google could find them. The day the PR was release it moved to the top of the SERP for searches for the brand as expected. The press release was syndicated by PR Web, a well-known service. The press release was syndicated on the business pages of newspapers such as San Fransisco Chronicle. It was also syndicated to a variety of other news blogs such as Thrillist and Break.com. These outlets posted the blog some with and without links, images and video. Niche blogs such as Tastydays and SmokingMeatsForum also posted the press release. Tasydays and SmokingMeatForum supplemented the PR, its images and video with some unique content.
Tweets also appeared...less than an hour after Google indexed the release the tweets began. The first was a blogger, then retweets including comments surrounding the original tweet.
Longtail results were also positive. "Stuffed Hamburger Press" is no doubt a highly contested word, and for at least the short term Stufz earned a top spot over the likes of Amazon, William Sonoma and ebay. The dominance of the top spot held for several days before reliquishing it to these internet powerhouses.
I would estimate the PR release was around $200 and I would conclude that Stufz was satisfied with the results.
