The simple reason for your lower ranking on Yahoo! is probably that
website owners can pay Yahoo! (or Overture, Yahoo's main source for
search results) for higher placement in their search results.
However, there is good news: It is estimated that 80-90% of all Search
Engine traffic comes from Google, so your situation is *far* better
than the reverse would be.
There is something that you can do that would almost certainly improve
your ranking in both Google and Yahoo! search results: submit it to
the DMOZ Open Directory. Both Google and Yahoo! use DMOZ as a guide to
indexing websites, because it is human-edited for quality.
The DMOZ Category which probably best fits your website is
Society: History: By Time Period: Twentieth Century: Holocaust: People
You can submit your website, http://www.warsawuprising.com , at the following link:
Be VERY sure to read DMOZ' submission policies and instructions carefully!
Submit your site once *** and ONLY once ***! It is rumored that
multiple submissions can make the Editor of your Category testy,
possibly causing your site never to be listed in DMOZ.
Normally, after 6 months, if your site is still not listed, you can
write to the Editor of your Category, explain that you submitted your
site 6 months ago (be sure to include the URL), and nicely request
that they consider adding your site to that Category.
Unfortunately, your Category has not yet acquired an Editor. If this
is a subject that is of high interest to you, you might consider
volunteering to serve as an Editor for your Category:
According to DMOZ' Editor Application Information:
"Your chances of becoming an editor are greater if you apply for a
small, underdeveloped category to start (generally categories with
less than 100 sites)."
so you might stand a decent chance of being selected to edit this category.
Applicants are highly screened for quality, so if you do apply, you
will want to read the "Become an Editor at the Open Directory Project"
page *very* carefully (be sure to follow all of the links and read
those, too), then take your time on the application and do a really
good job. Have someone who is good with English writing and spelling
look over your application and offer suggestions for corrections and
improvement before you submit it. (I recommend no more than 1 of your
suggested sites be for the Warsaw Uprising -- definitely NOT your own
site -- the suggestions should be just really good sites that fit the
Category well -- and are not already listed in DMOZ in this or any
