From my experience, when a site is built up and marketed correctly...a typical visitor couldn’t care less about the domain name (of course within reason) as long as the information is relevant.
On the flipside, I am also very well aware of the benefits and importance of a generic keyword domain; great for type in traffic, keyword branding aspects and it may lead to even a higher resale value, but I also understand the commenter’s situation below.
If you were competing in an ultra competitive market where a keyword rich domain would help the end user know exactly what your site is about, but can’t buy the Keyword.com, KeywordKeyword.com or even any of the top KeywordKeywordKeyword.com domains (even the 3 keyword phrase terms are ultra competitive) because they are all built into full working corporate entity sites and/or are way out of range for what we can afford - - do you think there is any value at all in buying an available eKeywordKeywordKeyword.com domain (again with the notion that even the 3 keyword phrase terms are very competitive and lucrative)?I think a domain beginning with “e” and then followed by a keyword, etc. is a very 1990’s style - but I am really curious to know your opinion. But then on another hand, I thought a site offering real estate services (for example) with a domain eRealEstateServices.com (for example) would be better than SteveLicensedAgent.com (again just an example).
…What’s your opinion?
But, I don't think it's going to have any type-in value, and may or may not have any keyword value, depending on how well the "e" fits with the keyword, and whether it creates a separate word in doing so. If you're selling gads, and your site is egads, you've lost any keyword advantage. Bad example, I know.
