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.
·
The good meta tags
- · 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.
- · 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.
- · 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
- · Social meta tags – 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 tag. Let's make this clear: In terms of indexing and
link following, if you don't specify a meta robots tag, they read that as index,follow.
It's only if you want to change one of those two
commands that you need to add meta robots. Therefore, if you want to
noindex but follow the links on the page, you would add the following tag
with only the noindex, as the follow is implied. Only change what you want
to be different from the norm.
· <meta name="robots" content="noindex" />
- · Specific bots
(Googlebot) – These tags
are used to give a specific bot instructions like noodp (forcing
them not to use your DMOZ listing information, RIP) and noydir (same, but instead
the Yahoo Directory listing information). Generally the search engines are
really good at this kind of thing on their own, but if you think you need
it, feel free. There have been some cases I've seen where it's necessary,
but if you must, consider using the overall robots tag listed above.
- · Language – The only reason to use this tag is if
you're moving internationally and need to declare the main language used
on the page. Check out this meta languages
resource for a full
list of languages you can declare.
- · Geo – lastly said, these meta tags are
supported by Bing but not Google (you can target to
country inside Search Console). There are three kinds: placename, position
(latitude and longitude), and region.
· <META NAME="geo.position" CONTENT="latitude; longitude">
· <META NAME="geo.placename" CONTENT="Place Name">
· <META NAME="geo.region" CONTENT="Country Subdivision Code">
- · Keywords – While no good SEO is going to recommend
spending any time on this tag, there's some very small possibility it
could help you somewhere. Please leave it out if you're building a site,
but if it's automated, there's no reason to remove it.
- · Refresh – This is the poor man's redirect and
should not be used, if at all possible. You should always use a
server-side 301 redirect. I know that sometimes things need to happen now,
but Google is NOT a fan.
- · Site verification – Your site is verified with Google and
Bing, right? Who has the verification meta tags on their homepage? These
are sometimes necessary because you can't get the other forms of site
verification loaded, but if at all possible try to verify another way. Google allows you to verify by DNS, external file,
or by linking your Google Analytics account. Bing still only allows by XML file or meta tag,
so go with the file if you can.
·
The bad meta tags
- · Author/web author – This tag is used to name the author of
the page. It's
just not necessary on the page.
- · Revisit after – This meta tag is a command to the robots
to return to a page after a specific period of time. It's
not followed by any major search engine.
- · Rating – This tag is used to denote the maturity
rating of content. It seems as if the best way to note bad images is
to place them on a separate directory from other images on your
site and alert Google.
- · Expiration/date – "Expiration" is used to note
when the page expires, and "date" is the date the page was made.
Are any of your pages going to expire? Just remove them if they are (but
please don't keep updating content, even contests — make it an annual
contest instead!). And for "date," make an XML sitemap and keep
it up to date. It's
much more useful.
- · Abstract – This tag is sometimes used to place an
abstract of the content and used mainly by educational pursuits.
- · Distribution – The "distribution" value is
supposedly used to control who can access the document, typically set to
"global." It's inherently implied that if the page is open (not
password-protected, like on an intranet) that it's meant for the world. Go
with it, and leave the tag off the page.
- · Generator – This is used to note what program created
the page. Like
"author," it's useless.
- · Cache control – This tag is set in hopes of controlling when and how often a page is cached in the browser. It's best to do this in the HTTP header.
- Resource type – This is used to name the type of resource the page is, like "document." Save yourself time, as the DTD declaration does it for you.
