Just noticed that on searching “california sales tax rate” on Google there is a Jump to “California” link to Wikipedia’s Sales Tax in United States page. It seems like Google is using the internal link ‘#’ to have people “jump” to a particular section on the page. However, not all the states have “Jump to” links. New York, Oregon and Hawaii are a few states without the jump to link which I searched for. Nevada did have a jump to link .

Has anyone else seen this for websites other than wikipedia? Like Bing, has Google started indexing links with pound/hash sign? The Jump to links are not present for all the states because Google adds the “jump to” links based on link backs? This should be an interesting mini-project to look into. I will add more details here as I find out more about it.
