Welcome to the Q&A Forum

I would second Mike's points.  The ending in a slash also helps out in systems like Google Analytics.  GA uses the ending slash to organize traffic reports for one section of a site versus the other.  You want to make sure that you set this up so that GA puts the right pages in the right directories for aggregate traffic reports. My preference is to use the ending slash - most people think of the ending slash as a folder with pages that are sitting inside it (even though many modern CMS make this moot) and so various types of reporting software will often reflect that. That said, I currently run a site that does not use the trailing slash and as so it can "work" as long as you know the ins and outs of things. The key is to be consistent in your use of a slash or not.   Often, it is in your own template or content where you are either forgetting to put a slash in (or leave out).  I would also recommend 301 redirects in place so that if you do not have a trailing slash in a url where there should be one (or vice versa) it will 301 to the proper url.  You can then run a spider on your site and see if there are any 301s that pop up to show any issues with the missing slashes etc. Cheers!

There's no telling. I'd say wait at least a month after submitting a thorough disavow to see any changes.

Aditya, If the dynamic content is focused enough and your page title and back link anchor text correspond to the focused content you may be able to remain fairly steady in the rankings--depending on the term and the competition.  If the dynamic content is all over the map and the rest of the on-page/off page SEO  isn't well focused you'll likely have a tough time of it.

OK, strictly from an SEO perspective as you request: Slight, but potentially worthwhile.  There has been a lot of talk of lexical co-occurrence or co-citation (co-occurrence would be more accurate) that talk about Google being able to recognise your website or brand as an authority in its industry even without links.  In short, if your site can be cited on a number of authority websites, even without links, Google may see it as an authority and promote it in search engine results.  Here are a few relevant posts: http://moz.com/blog/prediction-anchor-text-is-dying-and-will-be-replaced-by-cocitation-whiteboard-friday http://www.iacquire.com/blog/its-not-co-citation-but-its-still-awesome/ I think we're a way off seeing this as a major part of the algorithm, but there's no harm in preparing for it. More influential than 1), but in essence it is a link to your site that is telling Google not to pass on any PageRank, thus it shouldn't give any SEO benefit.  There are a few case studies that, over time a nofollow link will pass value (such as this one), but I wouldn't see it as beneficial as a dofollow link. The biggest benefit SEO wise.  If the link is relevant, contextual, from a page with not a lot of outbound links and on a quality website, it can be a great link for your site.  Of course, if the link comes from an irrelevant site, with loads of spammy links, lots of outbound links and your link appears in the comments, footer or blogroll, it could actually do more harm than good.  So it obviously pays to research the site before hand. Having said all that, I'd always combine guest blogging with engaging with an active audience, not just exclusively for SEO.  But as requested, there's my analysis and I hope it helps!
