But after reviewing some backlinks pointing to Yahoo! today, I noticed quite a few adult-th...
I've lost count of how many clients have requested that music be playing in the background of their website. As a professional web developer with a few too many years of implementing ridiculous requests, I've acquired quite a knack for convincing a client that music is a bad idea. The...
I've been working over Labor Day weekend a bit, reviewing sites for clients (and friends) and continually find that site architecture best practices are being ignored. Since Monday isn't a holiday globally, I thought it would be worthwhile to provide a quick peek into what I'd recommend on the structural side of SEO: Dynamic URLs - If it's even remotely possi...

Many of the client issues we've been working with recently have centered around canonicalizing, re-directing and structuring URLs for content. Marketing, sales, executives and IT departments all seem to have a unique viewpoint on these matters, making compromise and agreement especially difficult.

Just wanted to start on a thread on the subject of internal 301 re-directs. What's been your general experience when re-directing a page or set of pages to the "canonical" or new version?
