Optimizing images for maximum leverage
SEO does not have to be limited to text only. A picture can speak volumes especially if the images are optimized with the right keywords.
Using a relevant and clean image sends a message faster than text does. The picture should be able to convey what a post or information is about.
Aligning the picture to the top left or right is a good idea as it keeps the focus and conveys the message at the first glance.
Pick a related keyword or keyword variation related to the content of your blog post or webpage. Instead of naming the picture as pic1 or pica use the keyword that sums the information on the page. This keeps the focus on the keyword.
Use alt text so that search engines can identify what the image is about. There is no need to overstuff with keywords. Just a few relevant words in the description should be good enough.
Images should not be too heavy to load. Keep the file size under 25K.If you can resize an image instead of scaling it down the great!
By defining the exact size of the image through HTML it makes load time quicker as instructions for search engines become clearer.
