The Wonderful World of SEO Meta Tags [Refreshed for 2017]

Author: Kate Morris / Source: Moz

Meta tags represent the beginning of most SEO training, for better or for worse. I contemplated exactly how to introduce this topic because we always hear about the bad side of meta tags — namely, the keywords meta tag. One of the first things dissected in any site review is the misuse of meta tags, mainly because they’re at the top of every page in the header and are therefore the first thing seen. But we don’t want to get too negative; meta tags are some of the best tools in a search marketer’s repertoire.

There are meta tags beyond just description and keywords, though those two are picked on the most. I’ve broken down the most-used (in my experience) by the good, the bad, and the indifferent. You’ll notice that the list gets longer as we get to the bad ones. I didn’t get to cover all of the meta tags possible to add, but there’s a comprehensive meta tag resource you should check out if you’re interested in everything that’s out there.

My main piece of advice: stick to the core minimum. Don’t add meta tags you don’t need — they just take up code space. The less code you have, the better. Think of your page code as a set of step-by-step directions to get somewhere, but for a browser. Extraneous meta tags are the annoying “Go straight for 200 feet” line items in driving directions that simply tell you to stay on the same road you’re already on!

The good meta tags

These are the meta tags that should be on every page, no matter what. Notice that this is a small list; these are the only ones that are required, so if you can work with just these, please do.

• Meta content type – This tag is necessary to declare your character set for the page and should be present on every page. Leaving this out could impact how your page renders in the browser. A few options are listed below, but your web designer should know what’s best for your site.

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 

• Title – While the title tag doesn’t start with “meta,” it is in the header and contains information that’s very important to SEO. You should always have a unique title tag on every page that describes the page. Check out this post for more information on title tags.
• Meta description – The infamous meta description tag is used for one major purpose: to describe the page to searchers as they read through the SERPs. This tag doesn’t influence ranking, but it’s very important regardless. It’s the ad copy that will determine if users click on your result. Keep it within 160 characters, and write it to catch the user’s attention. Sell the page — get them to click on the result. Here’s a great article on meta descriptions that goes into more detail.
• Viewport – In this mobile world, you should be specifying the viewport. If you don’t, you run the risk of having a poor mobile experience — the Google PageSpeed Insights Tool will tell you more about it. The standard tag is:

<meta name=viewport content="width=device-width, initial-scale=1"> 

The indifferent meta tags

Different sites will need to use these in specific circumstances, but if you can go without, please do.

• Social meta tags – I’m leaving these out. OpenGraph and Twitter data are important to sharing, but are not required per se.
• Robots – One huge misconception is that you have to have a robots meta…
