Nielson NetRatings reports that in November 2007, searchers used Google 57.7% of the time.
Google has been steadily increasing it’s marketshare, while Yahoo and MSN are declining. A look at this chart of search volume gives you some cold, hard facts:
Google = 57.7%
Yahoo = 17.9%
MSN = 12.0%
When I’m teaching my SEO For Everyone class, I focus strongly on getting good results in Google. Even if Microsoft buys Yahoo (as hinted about in this Motley Fool article), the combined result still won’t equal Google’s power and scope.
What does Google care about? Content. Pure and simple, Google loves a site with lots of content. And even better, Google loves a site where there’s continually new content. This is a vote for adding new stuff to your site. If you write a newsletter, add your newsletter articles to your site after each publication of your newsletter. Put a blog on your site. Interview people in your industry and put those on your site. Always be thinking of ways to add content.
Of course, Google loves a site that other sites link to. You can create a sophisticated link strategy, but here’s a hint: create content that others want to link to, and they will.
Should you ignore Yahoo! and MSN? No. But your first priority when optimizing a site is to figure out what Google wants and give it to them. You don’t even have to search far: Google Webmaster Central will give you some tips.
