You have to be selective in what you pick to emphasize though and try not to go overboard with too many keywords. You also have to be pretty good at figuring out what they person is looking for with keyword phrases as well. In other words, take this article. Something like drawing search engine spiders to your blog would be something I think one may be searching for so I would emphasize that for the engine crawlers to find. Or see how I used italics in the phrase above for “crawling your site”. All anticipated keyword phrases. You get it? It is quite simple really and the spiders will love it. Here are the examples you may use to highlight your keyword/phrases in your blog posts or website articles. Minus the spaces. I was a bit lazy to make a graphic for it.
< b>BOLD< b />
< strong>Still BOLD< /strong>
< em>Italics< /em>
Any way… try to be gentle when doing this though. Too much can be overload and get you ignored.
