Web pages that include Twitter share buttons and links are seven times more likely to be mentioned in tweets, according to a new study by SEO firm BrightEdge. Yet 57.5 percent of the top 10,000 Web sites do not include Twitter buttons, BrightEdge found.

A study from BrightEdge examining the prevalence of social plugins on the home pages of major sites shows that Facebook is still the most dominant social button on the web. Google +1, however, is growing quickly, having seen a 28 percent increase in adoption over the last month.

Google+ is not even two weeks old yet and is already becoming a social networking favorite among early adopters.

A study has found that Google's +1 button is now more common than Twitter's tweet button on the home pages of the 10,000 largest sites. In fact, the +1 button is now on 4.4% of those sites' front pages -- a 33% increase from a month ago, according to search-engine optimization company BrightEdge.

Sites that have implemented a Twitter "tweet" button are seven times more likely to have their content shared, a report from BrightEdge said Thursday.

In a recent report released by BrightEdge, an enterprise SEO company, stats were released showing correlation between social buttons and social shares. Data showed that pages that displayed the Tweet button saw 7 times more social media mentions than pages that didn’t feature the button. This data was pulled from the “top 10,000 sites on the web.”

Websites that display Twitter’s Tweet button on their homepage get seven times more social media mentions than sites without the button, according to a new report out today from enterprise SEO platform provider BrightEdge. That figure is based on an analysis of more than 4 million tweets.

Microsoft's Bing search engine and MSN appear to have tied the knot with Twitter in a commitment ceremony played out online Tuesday afternoon. In a series of posts back and forth between the Bing and Twitter Twitter accounts, the two sides agreed to "stick together and do bigger and better things".

What happened in search today, as reported on Search Engine Land and from other places across the web.

A little more than a year after its launch, SEO management platform BrightEdge is re-branding itself as something quite bigger with the release of the S3 platform, which pulls together site, search and social data for multi-channel brand optimization and marketing.
