Search terms should be written out in text, instead of graphics. If you do use pictures, be sure to give them alt tags. The alt tags in your pictures are almost as important as text. It’s also a good idea to put some of your key words in links to other pages. In the eyes of a search engine it is almost as good to have a link to a page full of the content that the visitor is looking for as it is to have the content that the visitor is looking for on your page.But i want to know that is it perfect to use alt tags? Your opinions?Thanks.

Alt tag known as alternative text and it is so helpful to image optimization. It is used in HTML and XHTML for image and area tags and it is not necessary to use. You can use the keyword or description in Alt tag. It is so helpful when your browser not supports to present image at that time Alt tag’s text are display on that blank place and that text may be keyword, name of image or description of image. 

Alt tags are useful you know it then what you think about perfection.its really nice for using it.

Alt tags of the images are very useful if they are stuffed properly with the targeted keywords. They really add value to the optimization of your page. Also, always remember that the images should be relevant to the keyword.

First of all "alt" is not a tag. It's one of the attribute for "img" tag along with "src" attribute. This is one of the common misperception about alt attribute that it is a tag. Now about it's benefits. It gives search engines an eye to look about what a image is, as search engines are unable to read image. Also, it provides alternative information about an image to a user if for any reason a user cannot see the image. IE version below IE9 used to provide a tooltip for an image using alt attribute. Now IE9 and Firefox(all versions) use only Title attribute to show tooltip for image. But it doesn't mean that alt has lost its value. Title is for browsers and alt is for search engine. Use both wisely to achieve your goal - ranking + usability.

"alt" attributes are also used for screen readers (for the blind) and certain graphics-less browsers (e.g., lynx), so make them meaningful to someone listening to the screen being read. Don't just stuff them with keywords in hopes of improving your search results. Some people on very low speed connections turn off graphics, and so depend on alt to tell them what a picture is.

Trivial graphics (bullets, spacers, etc.) should not get alt or title attributes -- it's just a waste of resources. alt attributes should only be a description of what the picture is (for the benefit of a blind user, or someone with a text-only browser, or a search engine spider), and title should be used for any tooltip you want to be shown (on most tags). Unfortunately, earlier IE versions flouted the industry standards (what else is new?) and used alt also as the tooltip entry, unless overridden by an explicit title (even ''). Therefore, it's good practice if you use an alt attribute to always give a title attribute, even if it's an empty string (i.e., you don't want a tooltip).
