Tip 4: Underlining is Under-rated!
..............................................................................................................
Underline important keywords in the content of your page.
Underlined keywords and phrases can help search engines place emphasis on certain points within your content. It's not going to make or break your site, but it can add a little push to certain phrases.
Use underlining sparingly, though. Sometimes visitors will confuse underlined words for links. Too much underlining can make text look unnatural and, in some cases, even unreadable.
