Another good tip for SEO is actually the types of text you can use in a webpage. There are several different types of text which search engines see as more important types of text than others.

1) H1 - H1 text in my eyes is the most important type of text to use if possible. Search engines see H1 text as very important text, and it is a really good idea to get all your keywords into this particular format.

2) Bold Text - Search engine will also give a certain type amount of ranking power to bold text compared to standard non-bold text. It can be useful to use bold text occasionally if it looks ok on your page. I would not be too concerned about bold as long as you can get your keywords into the H1 text.

3) Strong text - This can be used for highlighting text instead of using the older bold tag. You can use the strong tag to highlight the words 2 or 3 times throughout the page.

4) Links - If you use links to inner pages, try using your keywords to do this - this will give the pages you are linking to extra power for the search terms you are using. For example using 'text format for SEO' linking to a page which has search terms for this phrase will benefit the page for that search term.

So these are just a few ways in how using different types of text can help you when you are optimising a web page for keywords. The most important type of text for search engines is the H1 text - try and get this text as close to the top left hand side of the page as possible as search engines read from the top left.
