I have noticed a lot of phpnuke theme designers making the mistake of not using the heading tags for the title of the news articles.  Until recently I didn't understand the importance of the heading tag.

Header tags and SEO.

The bolded text above is really a header tag. Using Header tags tells the search engine what "words" are important in the context of your page.

Consider <h1>,<h2>,<h3>, etc.. to be the way that you highlight important keywords.

Different browsers interpret the Header tags in different ways. The format for them is always the same though: <h4>Header tags and your rankings.</h4>

There are several different pre-set sizes for header text using tags. They range from H1, to H6. You should use them to highlight your chosen keywords, and try to avoid fluff words - remember, you are writing for people not machines, so if you need a pronoun -- use it.

In other segments of this website we have used blackbeltdomain.com as an example. Go check out the bolded text there and see how they are using Header tags to stand out for their chosen keywords.

Your rankings will suffer with out the proper use of Header tags, so don't leave them out of your planning stages of search engine optimization

I think a lot of the problems is the way a heading tag can throw off your design. In most cases heading tags are font sizes of 20-30 pixels. That can really cause a layout issue. I use CSS to remedy this issue in my phpnuke article layout.

h1 { font-size: 220%; }
h2 { font-size: 190%; }
h3 { font-size: 160%; }
h4 { font-size: 130%; }
h5 { font-size: 100%; }
h6 { font-size: 70%; }

You can use either the % character px(pixels). Depending on our style. Using this technique is sure to help your customers Search Engine Position. SEO is by no means complicated or hard. It just takes work. I would like to see more phpnuke theme designers making an obvious effort at improving the quality of their themes to be search engine friendly.
