Yerfdog recently put me on to a hot search engine optimization (SEO) tip. Google Image Search is an invaluable yet underutilized tool for web developers interested in increasing their Google PageRank.
An "img" tag contains a few different sections:
- src - the address of the image file
- height; width - the image dimensions
- alt - alternate text for the image in text-only browsers or browsers with images turned off
- title - the markup title of the image
The "alt" and "title" text are completely underused by most developers though. Very few people take the time to label their pictures, yet this is one the main ways GIS indexes pictures (along with the picture filename).
If you view the HTML of this page, you'll see the picture of the SEO girl at right is using these functions to the fullest. Let's hope GIS crawls and indexes it soon!
