If you want your web pages to create a buzz on social media, you need to make it easy for your visitors to submit your posts to their favourite social bookmarking sites. Adding some buttons at the bottom of each post is a great way to help your readers and give them a visual reminder to submit your content.

This is a list of icons representing social bookmarking sites that are free to use. Some are distributed under the terms of one of the Creative Commons licenses or other, similar, conditions so be sure to check the terms of the license and attribute the author where necessary:

Pretty much all of these icons sets have made it into my delicious bookmarks so you can always join my network to keep abreast of any new finds that I make.

I hope I have correctly attributed the original authors (it can be a bit tricky with all the icon aggregators around). If you think I’ve made a mistake, then please leave a comment or contact me directly. Oh and, by the way, see those little social bookmarking icons at the bottom of this post? Please use them, thanks :-)
