If you are working, you are expected to understand the language of business. Those terms range from "bottom line" to "market share." That's why from the get-go in our careers we were mentored to read The Wall Street Journal daily. That language should be integrated into a professional vocabulary.
Currently, the language we are also expected to understand is that of search engine optimization (SEO). It's become vital to the success of any business which leverages digital to market, sell, influence, and brand. Even if your specific tasks don't involve those front-line activities you still must be able to join in a conversation about SEO.
If you are clueless about the basics of SEO you will be labeled as "old." It's that simple. I had prepared a speech for a major lawyer. His generation is Baby Boomer. During the question and answer session, he was asked about how his firm approaches SEO. Duh. He never checked that out with the marketing people.
In the audience faces fell, along with his credibility. He had wasted the law firm's resources in being there to attempt to develop new business for its estates practice. "Old" translates into "out of touch."
How to bone up on SEO? A free daily guide is Web Marketing Today. Its editor-in-chief is my own digital mentor, Paul Chaney. Back in 2009, Chaney had published what was then a brisk seller "The Digital Handshake."
