I don't have a pile of empirical evidence to support my hypothesis, but I'll throw it out here for everyone to pick it apart just the same. I was looking at the kw tracker for several sites I maintain. What struck me the most is how the sites with static urls did not suffer terribly from the update. The sites with dynamic urls, and with only two variables in the query string, have suffered significantly. For example, if you search for 'skid unit', in G the page which was #1 is now something like #121. The page is still #1 in Y. This alone is not proof, I know. But it is one example of several pages that have suffered a similar fate. Pages in G that seemingly have little to do with skid units come up now ahead of mine. Since I use IIS on a windows server, I'm looking into buying isapi rewrite to be able to convert the urls into static strings for the SE's. It's just a theory, but I think it bears some further investigation. I guess I'll know for sure when I implement the new urls and see how G reacts.
I'm not sure what update you are referring to. The only hit I've noticed in the last few months that looks to be algorithmically-related is that (I believe) the Google duplicate content filter has become even smarter. (I've plaguarized myself heavily.) All of my pages are static, except for my two phpBB instances.
Hi Mopacfan U can easily write httphandlers in asp.net. It will take hardly an hour and will work in IIS. (.net should b installed) Just put your code in application begin request in global.asax.
I do not think it is really an issue. I use both and it really is not different for our site at all. Would be nice if someone had a clue.
That's exactly what I see as well.. I run several sites with phpbb forums (and some of them built on the phpbb script), and the static html pages are not affected at all there, but the dynamic .php ones are "kicked" out of the index every second day.. Here's an image I've shown in another thread. It's one of my largest sites, with 200-300 html pages, and thousands of forum pages. None of the html pages have been out of the index, but the forum pages jumps up and down like a yo-yo.. Even the index.php (without any dynamic variables) are gone from the google index today
I've had great success with SEO in the last 4 months or so, and none of the google changes I've heard of "hit" my pages til today. I have a large number of keyphrase pages (1000+), and although overall my rankings have only suffered an average of a few positions, some of my biggest traffic ones were knocked back from 1st to 3rd page... I've been analyzing pages that have gone up in the last day/month, compared to those that have gone down- what has already jumped out at me is: 1. Suddenly, google cares what case you use in URLs - pages where I capitalized the first letter of keyphrases have suffered, and you can see in the google search results that they're not bolding those words - though they don't care about case in <title>, they appear to want it all lowercase in the URL 2. Pages that haven't been updated since Feb or Jan suffered too. But this isn't conclusive yet- more analyzing to do. But I'm a little worked up, because my traffic today is about 20% what it usually is, and adSense earnings likewise.
At least for URLs of pdf files Google does not seem to bother. I do have one capital letter in URLs of pdf files and do not see any difference in ranking; see link to Bhagavad Gita below.
