If so, you may want to check out Referrer Detector, a plug-in for WordPress. What does it do?
Once a page on your site is submitted to a social media site every one who arrives to that page from a link on that site is greeted with a customizable message encouraging them to up vote your page if they think it’s worth sharing.
I’ve only had it installed and operating for a few days now and I’m already seeing a slight change in the traffic. Where most of my traffic has come from Stumblers, I’m now seeing Diggers and whatever people who use delicious are called showing up more often than they have in the past.
Of course, it helps if you have a convenient way for your readers to submit your site to begin with and for that I recommend ShareThis. I know. I no longer have ShareThis installed, but I have a perfectly valid reason for recommending it.
My theme is Thesis and thanks to SugarRae, I was able to customize it to display links to social sites without needing a plug-in nor having to dig through theme files.
And with that, I bid you good day (or night).
