I would appreciate suggestions on how to improve the content and ranking
of www.googleguide.com, which is an online interactive tutorial on
searching with Google.  Google Guide is a month old today!

Patience. All the major indexs, directories and search engines take
time to get around to looking at the enormous amount of material
that's out there. Have a look at Self Promotion at:

http://www.selfpromotion.com

for some useful tutorials and advice.

If i remember correctly, Google determines this by how many pages link
to your page.

They have a "link" program.   Alot better than some others.
