The scrollExtend plugin is designed to automatically load new content at the bottom of the screen (by appending to a DOM element) when the user scrolls beyond the element, much like Facebook does with their status updates. The existing infinite scroll plugin was primarily designed to integrate with Wordpress, which didn’t really suit my purposes.

There are two plugins encapsulated here – onScrollBeyond, which allows the developer to specify a callback to be run when an element is scrolled beyond (or the end of the document is reached), and scrollExtend, which is simply an implementation of onScrollBeyond that automatically loads new content via ajax when a user scrolls past an element.

Works with jQuery 1.3.2 and jQuery 1.4.2

Tested in IE6, IE7, Firefox, Chrome, Safari

Update v1.0.1 – fixed scrollExtend would get stuck in a disabled state if beforeStart returned false, even if it returned true on subsequent calls

For those who don’t know what it is, Raven is a web-based application for managing Internet Marketing campaigns. It’s a hosted solution, so there’s nothing to install, and it is either $79/month or $199/month depending on the number of users you’ll need. It has a whole host of features that you can check out on their website, but the three I’ll go over here are the SERP tracker, Link Manager, and Social Media manager.

SERP Tracker

Trending for Philadelphia SEO Firm

Initially, we weren’t too impressed with the SERP tracker in raven, but we found that it’s important to let it run for a few weeks before you can really see the value here. You don’t get immediate results the way you do with a local application like WebCEO, but I’ve come to really like Raven’t SERP tracker, especially since it supports graphing of SERP history (pictured left)

Conclusion

So far, we’re digging Raven as a campaign management tool. We’re currently using it on the $79/month plan, which is a pretty reasonable price for what you get, though I do think that they could stand to give more than two user accounts at that price. We don’t have any relationship with Raven whatsoever, so this isn’t supposed to be a promotional post, I just thought I’d post some thoughts after using the package.
