Finally an increase in traffic from Yahoo to my blog

I started blogging on this site in Nov’06 and since then it was always Google that referred the most of number of users from their search engine to my site for many articles that I have since posted. Yahoo on the other hand was very slow to pick up my pages despite the fact that I had submitted my sitemap to their search engine for better and faster indexing.

Since last few weeks, I see a lot of traffic from Yahoo search engine towards my blog. Their search referral traffic has increased almost by four times and I welcome that. I am not sure what they changed recently but whatever it be I appreciate it.

Having said that, Yahoo still fails to index my fresh content faster. Google does an awesome job of showing up my posted articles in their search engine results for various keywords within a week of an article getting posted. Yahoo on the other hand has my few months old content shown up in their search results. Could be that difference in search engine algorithm between Yahoo and Google, and also the index refresh frequency interval these engines uses.

Or, could it be that search engine optimization of my blog that I did was not in line with what Yahoo recommends?

Do you observe any increase in traffic from Yahoo search engine?
