Pop-ups, pop-unders, splash pages, marquees and other "in your face" techniques to grab your visitors’ attention are so yesterday . They create bad user experiences and is also likely to piss visitors off. Not only will they not work for today’s web surfers, they are bound to backfire.

Designers and bloggers all face a common goal – we want our visitors to read important site notices, to know about current happenings (giveaways, announcements, etc) or even encourage them to follow/vote for us on various social networks. We want all these to messages to be delivered and at the same time, to be assured that they are not irritated by the way we present it. But how?

You probably have an answer already, or some tricks up your sleeves. But if you don’t, here are some solutions that we’ve come to know of and we are going to share them with you.

7. Digg Digg Floating Icons

Digg Digg is a social plugin for WordPress. It allows you to float a row of social network voting badges/buttons of your choice on your WordPress blog.

Use it to display badges/buttons of almost any social network, e.g, Google+, Facebook, Reddit, Digg, StumbleUpon, just to name a few. You can also manually place icons wherever you want on your website, as long as you are comfortable editing the theme’s codes.

One small tip though – if you’re using a floating bar, it may be better to fix its position than to allow it to scroll. A floating bar that moves along with page scrolling can be irritating to some readers.
