One thing that can help is paying attention to your "meta" tags, which search engines read along with the main text of your site.
e.g. for the website I did for 1999judy,
Judy Archibald - Nail Artist and Nail Creation Team UK Educator I put in the following meta tags:
<meta name"robots" content"index, follow"/>
<meta name="author" content"Judy Archibald - Nail Artist and Nail Creation Team UK Educator, Manchester, England, UK"/>
<meta name"description" content"Judy Archibald - Nail Artist and Nail Creation Team UK Educator"/>
<meta name"keywords" content="Nails, Nail Enhancements, Acrylic Nails, Gel Nails, Training, Infill, Rebalance, Toenails, Nail Repair, Nail Art, Manicure, Pedicure, Nail Shape, Nail Polish, Ear Piercing, Bali Sun Airbrush Tan, Nail Creation Team UK, California Nail Academy, EzFlow, Caflon"/>
The "robots" meta tag is telling search engines to index the site and follow links in the site.
The "author" meta tag just lists details about the author of the site - in this case I put in Judy's details.
The "description" meta tag gives a brief description of the site.
The "keywords" meta tag gives a list of keywords of what the site is about. I will probably tweak this further in due course.
What also works well is to ensure that any images you have on your site have "alt" tags which give alternate text (search engines, just like people visiting your site using screen readers, won't be able to "read" text that is embedded in an image - e.g. if you want to use a fancy font for the title of your site so you create a GIF image with the text in a fancy font in it) - but if you include an "alt" tag for the image, then the search engines will read that.
Also, think about choosing a good domain name for your site that reflects your business name and what you do. Don't be tempted to skimp by using "framed" web forwarding, where the domain name provider generates some default HTML with a "frame" in it, but the content from your site is pulled in from some free webspace somewhere - as this will have an adverse effect on your site's placing in the search engines.
