The best way to attract people to your website, and keep them coming back, is to fill your webpages with valuable content in which your target audience is interested. The following guidelines can help you create a more effective and popular webpage:
In the visible webpage text, include words users might choose as search query terms to find the information on your website.
Limit all webpages to a reasonable size. Bing recommends covering one topic per webpage.
An HTML webpage with no images should be under 150 KB.
Make sure that each webpage is accessible by at least one static text link.
Don’t put the text that you want indexed within images. For example, if you want your company name or address to be indexed, make sure it isn’t displayed only inside an image of your company logo.
Add a Sitemap, which helps MSNBot to find all of your webpages. Links that are embedded in menus, list boxes, and similar elements aren’t accessible to web crawlers unless they appear in your Sitemap.
Keep your website hierarchy fairly flat. That is, each webpage should only be from one to three clicks away from the default webpage.
Techniques that might prevent your website from appearing in Bing results
The following techniques aren’t appropriate in terms of attempting to gain higher ranking with the Bing index. Use of these techniques might actually adversely affect how your website is ranked within Bing, and might even cause your website to be removed from the index.
Attempting to increase a webpage’s keyword density by add lots of irrelevant words. This includes stuffing ALT tags that users are unlikely to view.
Using hidden text or links. Only use text and links that are visible to users.
Using techniques, such as link farms, to artificially increase the number of links to your webpage.
