Many people overlook the title tag as unimportant, but the truth is search engines do look at it and weigh it when ranking your site. Again, try to repeat them two or three times if you can do so without compromising the description. Remember that the length of the description tag is best kept at under 25 words. If it's too long it will just get cut off by the search engines and not look very good when it's listed. Most search engines read the first 250 words of text on the page, so keep this in mind when writing your web page copy and if possible, use your most important keywords inside the first paragraph of your body copy.
Alt tags are where web designers write a short description of pictures used on the pages.
This is done as a convenience for those who surf the Web with graphics turned off. Make sure you include your most important keywords inside these tags, as search engines will look at them and some do use it when deciding ranking. Use your keyword phrases in your page names. Remember, keywords aren't a magical solution, but if you put some thought into it, and include them in as many places as possible of your site, you'll find you get a much better ranking than if you hadn't given it any thought at all. When it comes to the search engine wars every little bit counts.
