If you don't have a lot of time or expertise in custom tab creation, Pagemodo offers a quick and easy solution. Custom templates are great to manipulate to meet your individual needs.
For advanced users, it would have been nicer to have more custom HTML options. This area seemed to not interact so well once published.
It would be great to be able to manipulate templates more. For example changing the size of the photos and a drag drop feature to create your own custom template.
I hoped Pagemodo would enable me (the non-coding Community Manager) to build and manage custom tabs without assistance from our Development team. Unfortunately, to build a beautiful custom tab that is consistent with your brand identity, you will need to use CSS. Additionally, I saw a number of tech bugs, most of which were never resolved (for example I would enter text into an allotted box, but it wouldn't appear on my page). Customer support provided no help.
I've used Pagemodo to run various contests through Facebook and it has provided me with an easy way to really engage our followers. I've obtained over 300+ emails from our recent Halloween contest and have increased our Facebook "likes" by 15%.
