[Ref-Links] what people pay for link placement in search engines

[Eric Hellman <eric@openly.com>]

To embellish on my previous post, I thought I'd add the price per 
click that people are paying for the top spot at goto.com of the 
keywords I checked:


$/click 	KEYWORD             GOOGLE'S TOP RATED SITE
at GoTo
$1.51	"research"           The Materials Research Society http://www.mrs.org/
$0.70 	"engineering"        mechanical engineering home page 
http://www.memagazine.org/
$0.66	"medicine"            Nature Medicine: Home http://medicine.nature.com/
$0.56	"science"              Space Telescope Science Institute Home 
Page http://www.stsci.edu/
$0.53	"semiconductor"   MRS Internet J. of Nitride Semicond. Res. 
http://nsr.mij.mrs.org/
$0.49	"psychology"        Journal of Pediatric Psychology 
http://jpepsy.oupjournals.org/
$0.44	"chemistry"         Journal of Biological Chemistry http://www.jbc.org/
$0.37	"nature"               Nature Medicine: Home

$0.31	"physics"             Univ. of Pennsylvania

$0.28	"mathematics"      Society for Industrial and Applied 
Mathematics http://www.siam.org/


  (goto.com is a search engine that allows sites to bid on the top 
spot in the results page for a specific search term. )

The point of the post was NOT to suggest that Google is the right 
search solution for researchers (although libraries may like the 
price of $-0.01 per search (yes, they pay you to use it!)) but rather 
that link-generated placement in Google will come to generate 
significant collateral revenue for savvy publishers.
