3 weeks ago I paid Yahoo $300 to get listed in their search engine.
Currently, my site is up on both Yahoo and Google, but it's not where
I use to be. 98% of my traffic is now from MSN and my hits have
dropped from over 300 per day to under 100 hits per day after paying
the Yahoo Listing Fee. I get a total of 2% of my traffic from these
two search engines which were responsible for such a big part of my
business. I have a pop-up ad asking if you want to join my mailing
list on only 2 pages in my site. Neither one of those pages is my
index page. Last time I checked, I was rated a 1 in Google Page Rank
when prior to paying $300 for the Yahoo listing, I was listed as a 3.
My server has not been down at all to interfere with the indexing.
My question is:
"How can I increase my page rank in BOTH Yahoo and Google like I was a
few weeks ago"?

I have not altered my meta tags in any way since my site was indexed.
My URL is www.a1agifts.com

Please check my site and offer me some suggestions.

Thanks in advance.

As a note, a pagerank of "3" is pretty low in the first place, fyi. 
I'd strive for atleast a 5.

It just happened to a lot of sites, due to a big change at Google.
Some sites went up like mine :), some went down. Wait one month and
you might find you go up again...
