наверняка многие замечали, что гугл иногда принимает www.domain.com и domain.com за одно и тоже, а иногда за разные урлы.
пример: у www.penisbot.com PR5, а у penisbot.com PR4 (и это далеко не единственный случай)
т.е. получается, что часть сайтов ссылается на www.penisbot.com, а часть на penisbot.com, т.е. www.penisbot.com немножко теряет в PR.
если бы все ссылались на www., то PR был бы всеже немного больше (если не тулбаровский, то абсолютный уж точно)
собственно вопрос, кто как с этим борется?
можно конечно сделать редирект как например yahoo.com редиректит на www.yahoo.com, но для меня пока остается загадкой передача PR при редиректе (да и редирек ведь разный бывает).
А можно просто если www.domain.com и domain.com одно и тоже слелать просто внизу линк на www.domain.com, но при таком раскладе до www.domain.com всеже дойдет только часть PR от того, что могло бы быть.
делать сайт на www.domain.com, а на domain.com - только ссылку одну на www.domain.com и в .htaccess 404 редирект туда же не очень приятное решение :(

какие еще будут варианты?
или я что-то упустил и проблемы нет никакой?

гоню, все пашет.
убрал Options +FollowSymLinks - наверно у хоста уже стояло FollowSymLinks

круто, спасибо, а то я все время на php делал (приходилось каждую страницу <:) )

To WWW. Or Not to WWW.
Google PageRank Observations
By Bill Platt (c) 2003 http://www.thephantomwriters.com/
UNDERSTANDING THE WWW.

I came to the web with an itch to build content, and I needed to understand the technology utilized to build the Internet. Early on, I confronted the question about whether it was necessary to use the www. in my website URL. It really began to be a concern to me when I began to advertise my domain and I was limited to a certain number of lines and characters in my advertising. Although the www. only comprised four characters, those four characters sometimes made a significant difference in allowing me to have enough space to say what I wanted to say. Most every website on the planet advertises their website with the www. included in the URL. I wondered if dropping the www. would create a problem with people finding my site. The answer is that it depends on your web server configuration.
WHAT MAKES A WEBSERVER DIFFERENT FROM YOUR PC
Putting it in simple terms, a web server is put together in the same fashion as your own computer. Both have a set of directories, subdirectories and files which let you remain somewhat organized. The only difference between your computer and a webserver is the type of software that is loaded onto the webserver.
THE PURPOSE OF THE WWW_ DESIGNATION IN THE FOLDER NAMES
A webserver simply consists of software designed to allow external users to access the computer through a specific doorway in the system called a *port*. The webserver software handles all requests coming into the computer for information. All folders that represent different domains on the webserver are generally marked off with the www_ in the name of the folder. This reminds the system administrator that the folder is directly accessible from the Internet. The www_ designation is not needed by the webserver --- it is needed by the human operators.
DOMAIN POINTERS
Domain pointers are like shortcuts on your desktop. They are only files which point to another location on your computer. Clicking those shortcuts start new programs without your having to search for the actual program. Most webservers are set up to utilize these pointers to allow someone to direct access another folder on the webserver. For example, on my server I have a folder called *double-eagles* which is the home for another one of my domains. If you click the link http://double-eagles.com , that is actually a domain pointer directing your browser to open the folder http://thePhantomWriters.com/double-eagles The same process applies to the use of subdomains, such as URL's that utilize the www. For example, the URL http://archives.thePhantomWriters.com points to a directory on my server called http://thePhantomWriters.com/free_content
If you cannot access your domain name without using the www. prefix, then you should contact your webhost to get this feature enabled. The choice of using the www. or not should be made by your visitors, not your webhosting provider.
THE ADVANTAGE OF YOUR WEBSERVER RECOGNIZING BOTH
All day long when I surf, I type in the URL name without the www. included in the URL. I am often still surprised to see top name domains from whom you cannot access the non-www. presentation of their website! Can you imagine what would happen if someone put yourdomain.com into their browser and they received a Cannot Find Server error? *Bye-bye visitor... Wish we could have been introduced.*
WHAT ABOUT SEARCH ENGINE SPAMMING?
Search engine spiders are known to frown upon websites that introduce the exact same content under two different domain names. The search engine administrators generally view this as an attempt to gain an unfair advantage in their results. In fact, at one time I had read on the Google website that providing mirror websites could lead to your site being banned from their database. The common knowledge has always been that the search engines generally count only the www_ version or the non-www_ version of a website. They do not list both in their results as they understand that both versions are the same website. So, for the last two years I have made available the www_ version for my visitors, but only advertised the non-www_ version of the site.
THE GOOGLE PAGERANK SURPRISE
About one week ago, I installed two new tracking tools on my system to help me to guage the success of my advertising. Those two tools are:
http://toolbar.google.com/
http://toolbar.thephantomwriters.com/
Both require using a Windows operating system and Internet Explorer 5.0 or better for a browser, but both are exceptional tools if you are a webmaster who cares about tracking your traffic results.
MY BIG SURPRISE
Somehow, I managed to hit my domain with both the www_ prefix and without. The first time I did this, I simply assumed that my Google PageRank was bouncing from day to day with wide swings. The second time I had done it, I realized that Google was seeing the two URL's as two websites! The PageRank for the URL I advertise (non-www.) is currently a 5/10, and the PageRank for the URL I do not advertise (www.) holds a value of 2/10! The Alexa toolbar sees both as the same page and records the data for my domain the same in both cases. The difference between the two rankings is that the www. version has no links pointing to it. The non-www. version has 30 Google links pointing to it. It is important to note here that under the current guidelines of Google, a website must have a PageRank of at least 4/10 in order to be listed in Google's search results. Therefore, although there are hundreds of websites pointing to my website, only those with a PageRank of at least 4/10 will actually show up in the calculations for both Google PageRank and the Alexa results --- which utilizes the Google search results in their own rating systems.
WHAT I HAVE LEARNED FROM THIS EXPERIENCE
I need to make sure that I can get my URL on more sites with at least a 4/10 Google PageRank. The number of links pointing to a website do make a significant difference in the PageRank of the website. If my only goal is to build my own PageRank or to get better results in Google, I don't need to submit my information to a website that does not have a PageRank of 4/10 or higher. Putting my URL in my resource box and attaching it to a free-reprint article really can get my URL into hundreds of websites, some of whom will have a good Google PageRank. And finally, I hope that people who use the Google toolbar who visit my website come through to the non-www. version of my website --- or else they might just think that my website has no real value in the eyes of Google.
