what is that factor? it would be nice to have it quantified.
Tough to do UNLESS, you happen to own both domains and built sites and compare stats OR the .com owners share their stats
OR, you own both and park both with the same company...
OR, perhaps the .com has an affiliate program and you direct your DNS to point to them and you can measure traffic that way...
who know?
if not then why is it a selling point for .coms to say that the .net is developed?
There is the
perception that the .com will steal traffic away. That may be true. But, still hard to quantify. If the .net is established and marketed properly then there is this sense that someone else has done your work for you. Still, pretty risky to pump a lot of money into a name with the perceived notion that you are going to steal traffic.
And, again, who's to say that this is not NEW traffic?
Something I love to see is parked domains in all extensions except one - that one being the one I own.
There are an estimated 44 million parked domains in the .com and net (according to DuckDuckGo Toolbar). If this is true, then that is near 1/3 of all sites. When I look up domain extensions to see if this and that extension have a site, and they do not...IF out of the 5 gTLD's - .com, net, org, info, mobi - IF I am holding one of those top 5 and the others are parked pages...that means that 80% of my gTLD counterparts are parked. That, to me, is pretty staggering. Honestly, I have done this examination many times irregardless of the extension I am holding.
If 80% of my gTLD's counterparts (or competition, if you want to call it that) are parked and you decide to take your one gTLD and make a site...and you have traffic...
where is that traffic coming from?
Is it all new traffic? Are you stealing traffic from the other gTLD's being parked? Are you getting traffic because you index better than the others being that you have fresh and current content?
There are too many variables and I am not sure your question can ever be quantified with an accurate formula.
