Q: How do I determine the words that allow people to find my website easily? Is that through my wordpress back end?
A: What you are looking to do is alter your HTML head code by adding meta tags. Meta is the information used by websites like Google to learn about your web sites.
It is inadvisable to hide text on the HTML in the method previously used on aura.net. Google uses a clever algorithm and actually penalizes sites that try to trick it, placing keywords in hidden text is against search engine guidelines. A quick Google search for ‘hiding keywords in html’ will show many discussions regarding how Google ‘will get you’ and regards the practice as equivalent to ‘spamming’.
