I have been researching and optimizing my sites for Google since the beginnning of this year. When my sites were complete I submitted them to Yahoo as well as many other search engines. I didn't expect anything from Yahoo but they are listed on there now, while Google has put them on probation because they are new sites to the web as of this year (sandbox effect).
I accually have noticed that Yahoo seems to be a bit easier to optimize your sites for. Just wondering if anyone new about how linking works with Yahoo. Which types of optimizing work both the same with Google and which types of efforts are different. Would love to hear all opinions. Thanks.
