The meta description tag is where you should write a few sentences about what your company does.  This is very important to keep consise, short, but also convey what you are and what you do.  It is recommened that you keep it to roughly 2-3 sentences.  Longer descriptions could penalize your ranking by search engines as they might view it as keyword stuffing.

This is the sentence that clients will see after your name on a Google Search.  This should contain the key information you want to give them and motivate them to click on your site.  If you have what amounts to a long list of key words they are less likely to click on your link then if you say “James Doe photographer captures your wedding day with a mix of XX and XX” then if you have “Jame Doe wedding photographer town a, area b, city c, city d, county x, county w, etc.

Until next time!
