We've tested our ads, widgets, and layouts on all major blogging platforms (including: tumblr, Squarespace, Blogger, Wix, and Blogspot).
There shouldn't be any problems using ShopStyle Collective on most blog platforms. There may be some formatting constraints that some templates may cause with our Widgets or Collections. Often times, templates can override our script tags (this will mess up formatting) or certain stylization on divs or containers will cause strange scrolling issues. We'd highly recommend reaching out to your blog platform provider for best practices and troubleshooting tips!
WORDPRESS: At this time, WordPress-hosted sites (these will be Wordpress.com as opposed to self-hosted WordPress.org sites) only support individual product widgets as they do not allow scripts or iFrames. We recommend Blogger.com as a free hosting site that is compatible with our tools.
