Wrong.

Meta descriptions, despite their stereotype, can be broken down in a fairly simple way. The more content I create and the further I dig into inbound marketing methodologies, the more I realize how important meta descriptions are, and how a powerful meta description can make or break. I’ve turned to the experts many times when it comes to understanding meta descriptions, and I’m here to share what I’ve learned. Check it:

First Things First: What is a Meta Description?

Experts at MOZ explain meta descriptions as “HTML attributes that provide concise explanations of the contents of web pages.” What? Let me break it down … You know when you Google something, and a list of results come up? A meta description is those couple sentences under the title that describe the search result. My friends at HubSpot describe a meta description as “the snippet of information below the link of a search result.”

Stay with me – here’s a screen shot:

Basically a meta description is what is ready to help the searcher decide whether or not to click the link to an article or web page. A meta description helps convince or persuade readers to choose your site. Oh, and the bolded words within a meta description help note which words (keywords, in fact) match those in the search query. Nothing too complicated, right?

Do I Really Need a Meta Description?

So now that we’re on the same page and you’re fully equipped with the knowledge of what a meta description is, let’s talk about whether or not you really need one. There’s no reason to reinvent the wheel here – I turned to trusted experts and dug up some meta description gold.

The short answer to “Do I need a Meta Description?” is yes. The long answer? Yes, and here’s why…

1) Increase Click Through Rates & Improve Visits from Organic Search

The percentage of clicks consistently drops off as you go further down the page, because a more relevant result is, logically, usually at the top of search engine results. So, if your result is far down at the bottom (or not even on the first page of results), you’re already working shorthanded. This makes having a detailed, relevant, and eye-catching meta description that much more important. In short, the better your meta description, the more likely it is you’ll have good click through rates from organic search. – via HubSpot

2) Give the Right People the Right Information at the Right Time

Google uses meta descriptions to return results when searchers use advanced search operators to match meta tag content, as well as to pull preview snippets on search result pages, but it’s important to note that meta descriptions do not to influence Google’s ranking algorithms for normal web search. – via MOZ

3) Increase Visits from Social

Social sharing sites like Facebook commonly use a page’s description tag when the page is shared on their sites. Without the meta description tag, social sharing sites may just use the first text they can find. Depending on the first text on your page, this might not create a good user experience for users encountering your content via social sharing. – via MOZ

4) Use it to “Sell” Your Content

Although the Meta description itself doesn’t affect the ranking of a given web page, the side effects of a well crafted one can – well written meta description have been proven to increase click through rate, and in some instances time spent on the web page, and these metric DO play a part in the algorithmic rankings. – via Hallam

What Makes a Meta Description “Powerful”?

For every blog, web page, and piece of copy we write, we follow the best practice of creating a corresponding meta description. Now that you know why (see above) – here’s the how:

1) Write Compelling Content

Write a short sentence previewing the content or telling the searcher why they should read your post. Give them a clear benefit of clicking through and reading your post, if necessary. This is your chance to sell them on what you have to offer — informative, valuable content. – via HubSpot

2) Use 1-2 Keywords

The title tag and the meta description tags should include keywords relevant to the content of the web page they describe. This helps Search Engines understand what the page is about and index your web pages accordingly for relevant keywords or keyword phrases … The meta description tag should ideally target a unique keyword for each web page. Avoid keyword spamming and have each keyword only appear once. – via seoWorks

3) Aim for 155 Characters

Google actually doesn’t measure by characters – it measures by pixels. That is, it’ll cut off a meta description after a certain width. The reason we say 155 characters is to give marketers a benchmark to abide by. – via HubSpot

4) Avoid Keyword Duplication

It’s sometimes helpful to have a few descriptive terms in the title, but there’s no reason to have the same words or phrases appear multiple times. A meta description like “Foobar, foo bar, foobars, foo bars” doesn’t help the user, and this kind of keyword stuffing can make your results look spammy to Google and to users. – via Google Support

5) Eliminate Non-Alphanumeric Characters

Search engines identify alphanumeric characters, like hyphens, plus signs and quotation marks as HTML code and as such may not use the description as you intend it to be used. It is best to stick to plain text when it comes to meta description tags … Any time quotes are used in a meta description, Google cuts off the description. To prevent meta descriptions from being cut off, it’s best to remove all non-alphanumeric characters from meta descriptions. – via MOZ

To sum up the makings of a truly powerful meta descriptions, I’ll leave the final words to Google:

“Use quality descriptions. Finally, make sure your descriptions are truly descriptive. Because the meta descriptions aren’t displayed in the pages the user sees, it’s easy to let this content slide. But high-quality descriptions can be displayed in Google’s search results, and can go a long way to improving the quality and quantity of your search traffic.”

The Exception

As I get older – and wiser, of course – I find there is an exception to every rule. Meta descriptions are no different. There are instances where a meta description isn’t necessarily crucial. However, as I’ve noted above, conventional logic agrees that it use generally wiser to write a good meta description for any given page. Here’s the “but”, via MOZ …

If the page is targeting long-tail traffic (three or more keywords) it can sometimes be wiser to let the engines extract the relevant text, themselves. The reason is simple: when engines pull, they always display the keywords and surrounding phrases that the user has searched for. If a webmaster forces a meta description, they can detract from the relevance the engines make naturally.

It sounds tricky, but it’s pretty simple. If you have a page that lists several articles (think a blog or newsletter archive, or something like “your cart” if you’re ecommerce), it might be OK to forego the meta description. When in doubt, spend time writing an engaging sentence or two, and feel confident the right people will find the right information from you, at the right time.
