People identify with the logos of companies. Sometimes it might be how a person looking through search results knows to click on a link to your website. You can markup images using schema tagging as well. This will help search engines relate your law firm brand’s logo with other data about your business. Below is an example of what the markup would look like.
<div itemscope itemtype=”http://schema.org/ImageObject”>
<div itemscope itemtype=”http://schema.org/Attorney”>
<img src="lawyer-n-sons.jpg" itemprop="contentURL" />
