Here are a few to consider continued (part1http://www.dreamconsultancy.com.au/articles.php)…
6) Do not use images to replace text. They take longer to load, they really don’t look much better, blind people can’t read it and that text will no longer be searchable by the search engines.
7) Only underline links and make sure you have actual links underlined if the link is included in a paragraph of text. If you underline text to emphasize something but it is not an actual link, your readers will almost certainly be confused. The same goes for links that are not underlined. People may miss out on valuable information because they have no idea that the text leads to something more detailed or interesting.
8) Structure your text. Make use of bold headings, short paragraphs, bullet lists and tables if the information requires it. To better organize your thoughts, divide your article into sub-headings. Sub-headings make things easier to digest. Instead of tackling the entire article at once, try writing one paragraph at a time.
9) Use words in your content that people will search for. Search engines consider headings, page titles, bold and linked text to be more important and relevant and the precise wording of these sections of your content are extremely important.
10) Create a lot of links and use relevant keyword phrases as the link text. Ask other sites with similar content to link to your site and most important, tell them the text to use in the link.
11) Make good use of white space and allow your content to breathe. Don’t allow text to butt up against graphic elements on your site or photographs, etc. Don’t place too much emphasis on your navigation elements if content is important to your site. Allow users to easily read your message in a clean, uncluttered and — in the case of blinking text — non-irritating environment.
10) Write your own content. Use only content (pictures, text, videos …) made by you or with explicit permission, everything else probably infringes someone’s copyright.
