But where are all these free links? And can we take a few to go?

One note – you mentioned Google couldn’t spider dynamic URLs before 2006. I think you were just writing shorthand there, but they totally could. They’ve been able to index dynamic URLs pretty much forever. The problems came in if you have many parameters in the URL – like 4 or 5 or more… and also if you had session IDs. It wasn’t really a technical issue on there end, but just that when you have 5 parameters and/or session IDs it makes it almost impossible from a site management standpoint to be 100% consistent with your URL structure, so Google would end up indexing essentially the same page under 10 different URLs and you’d have lots of duplicate content issues and whatnot.

Anyhow, to me their blog post basically said “We’d prefer you to not re-write your URLs b/c 1) we want to know they are dynamic b/c it helps us do our job, and 2) its hard and you might mess it up so don’t try.

Neither of those seem very convincing to me.

Great idea and great post.

Thanks for the link man, some great reads.
