Before you do any advertising of your store, I’d put some kind of social marketing on all the pages. Imagine, a women clicking on “Facebook” button on “Fiona Sofa” page and sending it to all her Facebook friends with “Oh my gosh, I love this one” comment.

Problem:

I’m considering a social media bookmark and am on the fence about adding “AddThis” vs. simply just adding Facebook’s XFBML Like Button.
I still got errors for security on my pages every time they loaded.

Solution:

Because “Addthis” code is loading from unsecured location, you will get security popup during user registration and checkout.
Easy way to avoid security warning is to add this code to poweredby.tpl template:

{if $smarty.server.HTTPS ne ‘on’}

your addthis code here

{/if}

It allows you not to show unsecured code on secured pages.

Alternative solution:

We tried addthis but it was slowing the store too often because script and images are loading from their site. Can be set to load after the whole site is loaded but requires too many adjustments.

Finally we installed this add-on from xcartmods.co.uk

Check this out in one of our clients store:

and on every product page:

http://www.lfd-leatherfurniture.com/Fiona_Leather_Sofa.html

It had to be modified a bit for v4.4. I attached modified version we used (hope xcartmods.co.uk guys are ok with it. If not, I’ll remove the file)
