A description of how a font that is size H1 can be part of a good SEO strategy as the search engine spiders consider keywords in that font to be more important.
If you want to search engine optimize your web page keywords using fonts then you might want to consider using the web design software Front Page to design your site. As you may or may not know, search engine spiders look for a block of a text when they are indexing your site. The theory is that when they find a keyword or a phrase in font that is written in an H1 size that it will consider that word or phrase to be of the most importance and index it accordingly in the search engine’s database.
In this particular instance your SEO strategy would be to first of all make sure that you are using Front Page to design your pages in the first place and second of all make sure that you have titles using the H1 header as part of your web copy somewhere on the page.
Are there any drawbacks to this strategy of using the H1 font? First of all it is considered to be a large (and some would say quite ugly) font. Although it has a great positive impact on the search engines, human beings seeing this might think that you have very bad taste in web design. The problem with fonts that are too big on a page is that they look like a five year old designed them. Oversized headers simply look immature.
This means you need to use these H1 Front Page style fonts sparingly if you want to make a positive impression on your customers. This of course also forces you to choose just one or two really good key words or key word phrases to describe your site that hopefully in turn will be picked up by the search engine spiders when it comes time to index your site for the search engine page rankings.
