The HTML tag is meant to be a concise explanation of a web page’s content. Google displays your meta description beneath the page title in their organic results. While meta descriptions aren’t as important as page titles in your Google ranking, they do play a big role in getting clicks from users. People read descriptions as a preview of your page and use it to determine if your content is worth visiting. You should keep your meta descriptions to under 150 characters since Google won’t display text beyond that. You should also include target keywords in your text, since any words matching a user’s search query will be displayed in bold.
An important thing to note is the effect that localized searches will have on search engines. For example, say you’re in Atlanta and you’re looking for a photographer for your wedding. When you search “wedding photography” it wouldn’t be helpful to see results of photographers in Los Angeles. This is why Google takes into account where you are when you search for certain words, and shows you listings from businesses that are close in proximity to you.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
