The results stored in My Web are both shareable and searchable. To share, you select pages you want to share, and click Share button. Easy enough. You can share directly from search results as well, without adding page to My Web.

Once you have some pages stored in My Web, you can then easily search within those pages to find what you're looking for. This isn't a simple search of a description field like those offered by some browsers. This is an actual live search of just pages you've stored in My Web. Pages stored in My Web can be sorted by date, search terms, or URL. All in all, My Yahoo Personal Search is a very useful addition to Yahoo collection.

If you want to market an affiliate product through SEO, you can monitor top 20 results for a search on that product. You will know if and when your site breaks into top 20 results, and can watch it as it hopefully continues climbing to that first position.

There are other uses as well. SEO firms can monitor clients' results. Niche marketers can easily monitor both industry news and niche search results. You can even monitor search results for your best keywords and your own high ranking pages.

Google Alerts, though free, can provide valuable marketing intelligence to online entrepreneurs who take advantage of it.
