When we think of SEO, we all think of optimizing content and web pages. But images also play an important role in driving traffic to your site.
Here are a few tips from Google Webmasters to optimize images for Search Engines.
Informative image names
If the image names are self explanatory, it increases its visibility e.g., chandni-chowk.jpg instead of IMG456829.jpg. Always use keywords in image name.
Appropriate ALT text
The alt attribute describes the content of an image. This information is used to determine the best image to return for a user’s query. An alt text should be a description not keywords. Filling alt attributes with keywords (Keyword stuffing) results in a bad user experience and can cause the website to be counted as spam.
Content around image
The page the image is on and the content around the image (including any captions or image titles), provide search engines with important information about the image. It is recommended to provide good, descriptive titles and captions for your images. It is good to place images near the relevant text.
Don’t embed text inside images
Search Engines can’t read text embedded within the image. It is good to put content in HTML rather than in the image.
