A picture can be worth a thousand shares and creating share-worthy content can really help your search engine rankings. The trouble is that search engines can’t read images. Search engines are designed to only read the text on a web page. So make sure that any images on your website have some type of description that Google and other search engines can see and index. Otherwise, your image is only visible to those who find your website by other means.
It is important to make sure that critical contact information is not encapsulated in a pretty graphic. Google will completely miss it. Make sure your address and phone number are not built into the website design template as a graphic. Your address information is especially important to mobile and local search.
Fortunately, there are ways to help the search engines “see” your images and graphics. For example, you can use meta data and alt text to tell the search engines about the image. And, descriptive file names using keywords help images rank.
One thing to keep in mind is that images can cause your site to bog down and have a dramatic impact on your page load times. Slow loading websites are dinged by the search engines and can have an impact on how the site ranks. So make sure to keep the image size as small as possible without hurting the quality and it’s a good idea to resize the image before you put it up on the site. A good SEO firm can help optimize any images on your website as part of an overall SEO strategy.
