this is something that I think about occasionally.
what if I buy 100 keyword domains and then the day after google changes their algorithm so that much less emphasis is placed on the domain name when ranking for a keyword.
do you guys think this is a long time off?
hi btw my first post

im a web designer / developer but just getting into the domain name thing.
I think you need to consider what the algorithm is programmed to make happen. What is the objective? It seems to me that Google wants to return search results that provide the searching party with the most accurate, informative content available relating to the terms of the search. If we can agree on that, the next part is dictated by logic or common sense.
When the domain, UnstructuredInformation.com, provides accurate, informative content and the searching party has entered only the words "unstructured information" (with or without quotes), it would make sense to assume that a domain name that,
word for word, is an
exact match for the search query will have a higher likelihood of providing information on that specific subject matter than another domain name that is not an exact match.
Here's another way to look at it:
If the domain is datamining.com, it could have plenty of content without ever discussing the concept of unstructured information, but if the domain is UnstructuredInformation.com, it better damn well have information on unstructured information or somebody is getting punked!
Google's algorithim simply attempts to quantify the elements that that go into increasing the likelihood that a website is a good match for the the entered search. However, when a website attempts to be perceived as meeting the main objective, but in reality, does not, it is playing to the algorithm check-list instead of the actual audience. That's much more difficult to accomplish these days, but to the extent it can be done, once Google becomes aware of it, your result ranking will drop faster than leaded buckshot in an elevator marked, "Express Car Down"!
That is why it's best
not to view Google's search algorithm as your primary target or audience. To do so to the exclusion of your potential site visitors means you are playing games with the individual components that are designed to measure the effectiveness and popularity of a given website. Google doesn't like that. Instead, focus on your real audience, the people who submit the searches. Take good care of them, and 99% of the time, you will aslo be taking good care of the algorithm, too - be it, yesterday, today or tomorrow.
