Oops Major Blunder

Uggg, talk about a major bonehead error on my part. At some point in the distant past the page templates I created for the site all shared the same html header information. Turns out, I somehow wound up with a hybrid page type definition. In short, I coded the site in HTML 4.01 Transitional/EN, but somehow I had the 1.0 version definition that you would find in an XHTML doctype. Here’s what I had and I’m still in the process of correcting all 279 pages!

Big Oops: !doctype html public "-//W3C//DTD HTML 1.0 Transitional//EN"

What it Should Be: !doctype html public "-//W3C//DTD HTML 4.01 Transitional//EN"

I have noticed my traffic and page ranking has been rather lower then expected. In fact, my home page isn’t even showing a page rank. Hopefully this error once fixed across the site will correct any ranking issues but talk about a small but major blunder. Although, on the positive side of thing, I’m glad I caught this now because I have several hundred pages to upload in the coming months which if I carried this error through all of them too, that would have been a disaster. I’m such a dork, but a happy one! :o) Cheers all.

2009 Q1 and Q2 (early) Traffic Statistics for ClassNotes123.com

Two days early, but here’s the traffic statistics for my site. I ramped up pages and content throughout the first quarter of 09 and have continued to add pages over the past few months. Although, much of my recent efforts has been focused on optimizing pages and correcting some silly html coding errors which unfortunately are on just about every page. Oh well, on the positive side of things it provides me an opportunity to review each page and make any necessary changes.

As for the traffic statistics on ClassNotes123.com, there was a ramp up of visitors throughout Q1-09 followed by a predictable plateau in Q2-09. There was a slight roll back from the peak in mid March, which I’m attributing to the typical educational schedule in the northern hemisphere where most of my traffic comes from.
