Using ALT tags
What is ALT tags and why should I use them?
You have a web site. Your designer did an excellent job and it looks great. You have plenty of images, including one containing your business name, logo and slogan.
Though your site may look fine, it's not optimized to score high with search engines. Since search engines don't index images, they won't index any text your web site presents in image format -- in this case the above-mentioned business name and slogan. To fix this problem, there are ALT tags, which are basically images' descriptions.
Always add ALT tags to your images to make sure search engines recognize all the content on your site. ALT tags filled with keywords can also be used to boost your keyword frequency and help you achieve better rankings.
Avoiding Spam
Search engines don't penalize for using ALT tags or even for packing them with keywords. Still, to be safe you should adhere to the generally accepted rule of not repeating keywords more than 3-7 times.
ALT tags:
- Describe images
- Add keywords to site text
- Should be used for each image
- Make sites accessible to the visually impaired
