Below you will find many factors you should consider as you prepare your site for both humans and search engines. A title should be descriptive, and contain your keywords, briefly outlining the focus of that page. Alt Tags are words or descriptive sentences inserted into an image link. This tag is used by some search engines, and is quite easy to include. The alt tag also allows visitors surfing without images to understand the site better.
Most browsers display the alt tag as the image is loading.
Here is how to include the tag in the HTML source code. If you are using an editor to make web pages, it should be quite easy to include the tag. The visitor's browser is able to start displaying the page right away, because it knows where and how big your images will be . This ensures that your visitors can read the text on the site while they wait. If they have something to read while they wait, they are far less likely to leave while your page is still loading.
