There are a ton of things to consider for overall accessibility however one thing developers can do with limited knowledge of accessibility concepts is to use the keyboard to interact with your site(s). Can keyboard-only users complete all the tasks a mouse user can? If there are mouse-driven event handlers on controls, are there redundant keyboard event handlers where applicable? Are labels explicitly associated with form fields? Do images provide proper textual equivalents? Do color schemes provide sufficient color contrast per WCAG (https://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-cont...)?
