What Are Meta Tags?
Simply put, meta tags are tags within the HTML code of your website that describe the different components of your site to search engines. These tags allow Bing or Google search algorithms to read descriptions of the makeup of your site.
There are different types of meta tags that indicate different aspects of your site to search engines. See below for a definition of some of the most common tags:
- Meta Title Tag: An HTML element that communicates the title of a web page to search engines
- Meta Description Tag: An HTML element that summarizes the content of a web page for search engines
- Meta Keyword Tag: An HTML element that communicates target keywords related to the content of a web page to search engines
- Meta Robots Tag: An HTML element that instructs search engine bots on how to read the content of a web page
If you‘re not an expert in HTML but still want to incorporate meta tags into your website, many content management systems such as WordPress include SEO plugins that make it easy to add and edit meta tags.
Why Are Meta Tags Important?
While they themselves are not a ranking factor for search engines, high-quality meta tags are essential to effective digital marketing and technical SEO.
When your pages come up in search results, search engine users will read your meta title and meta description as the page title and the description of its content. Based on the poignancy of this metadata, searchers will make their decision on whether or not to navigate to your page.
With their prevalence in the search engine user experience, effective meta tags can increase conversions, decrease bounce rates by making the purpose of pages clear, improve on-page SEO, and provide a vetting system for any duplicate content on your site.

The Most Important Meta Tags for SEO
In this article, I'll walk you through the 8 most important meta tags for SEO:
- Title Tag
- Meta Description
- Canonical Tag
- Alternative Text Tag
- Robots Meta Tag
- Open Graph Meta Tags and Twitter Cards
- Header Tags
- Responsive Design Meta Tags
By using these meta tags, you can boost your website's SEO.
1. Title Tag
The title tag is the first HTML element that specifies what your web page is about. Title tags are important for SEO and visitors because they appear in the search engine results page (SERP) and in browser tabs.
For example, you can see the title tag in the browser tab header of this Templatemonster post.
The title element supports all browsers including Chrome, Firefox, and Safari.
Always add your title tag in the <head> section of your site:
<title>This is Title Sample</title>
Here are some good pointers for writing a title tag:
- Keep your title tag under 60 characters if possible
- Add words that indicate what your content is about, such as “How to,” “Review,” “Best,” “Tips,” “Top,” “Find,” or “Buy”
- Use long-tail keywords, or keywords with 4+ words, such as “is my site mobile-friendly” or “how to make a website mobile-friendly”
- Add numbers to your title, such as “9 HTML Tags That Will Improve SEO”
- Start your title tag with your main targeted keyword
- Don't stuff your keywords by writing anything like the following: “We sell custom cigar humidors. Our custom cigar humidors are handmade. If you’re thinking of buying a custom cigar humidor, please contact our custom cigar humidor specialists”
- Include a unique title tag on every page
2. Meta Description
A meta description is an HTML element that sums up the content on your web page. Search engines typically show the meta description in search results below your title tag.
Here’s an example of the meta description appearing on a search results page:
This is how you’d code a meta description like the one above:
<meta name="description" content="This is meta description Sample. We can add up to 158.">
Google does not use the meta description as a ranking signal. However, it still has a massive effect on your page's click-through rate (CTR) because it appears in search results and informs users what your page is about.
Lately, Google has changed the length of what it will show in SERPs. The search engine giant confirmed that it shortened search results snippets after expanding them last December.
Google's public search liaison, Danny Sullivan, mentioned that there is no fixed length for snippets.
The new average length of the description snippet field on desktop is around 160 characters, down from around 300+ characters.
Mobile characters for the search results snippets are now down to an average of 130 characters.
Here’s how to write a good description tag:
- Do not add duplicate meta descriptions.
- Add a clear call to action (CTA) in your descriptions like “apply today,” “check out ____,” or one of these 100 CTA phrases.
- Add your targeted keywords in descriptions.
- Add any discounts or offers you have.
That way, you’ll have a compelling description tag.
3. Canonical Tag
A canonical tag is an HTML link tag with the attribute “rel=canonical."
It’s used to indicate that there are other versions of this webpage. By implementing the canonical tag in the code, your website tells search engines that this URL is the main page and that the engines shouldn’t index other pages.
Use the following syntax to add a canonical tag:
<link rel="canonical" href="http://example.com/" />
4. Alternative Text Tag
Search engines can’t read images, which are a crucial part of many websites. Alternative text (alt text) is a way around that issue.
You should add proper alt text to images, such as the one below, so that search engines know how to interpret them.
That way, you can include inviting graphics on your website without damaging your SEO.
When creating alt text for your website, use the following syntax:
<img src=” http://example.com/xyz.jpg” alt=”xyz” />
Here are some tips for your alt text tags:
- Always use a proper description, and never stuff your keyword in this tag
- Use informative filenames
- Be clear and to the point
- Create an image sitemap
- Use 50-55 characters (up to 16 words) in the alt text
- Use an average or small file size for faster page loading speed – just don’t compromise the image’s resolution
5. Robots Meta Tag
The robots meta tag tells search engines to either index or non-index your web page.
The tag has four main values for the search engine crawlers:
- FOLLOW –The search engine crawler will follow all the links in that webpage
- INDEX –The search engine crawler will index the whole webpage
- NOFOLLOW – The search engine crawler will NOT follow the page and any links in that webpage
- NOINDEX – The search engine crawler will NOT index that webpage
Use the following syntax for your robots meta tag:
<meta name=”robots” content=”noindex, nofollow”> Means not to index or not to follow this webpage.
<meta name=”robots” content=”index, follow”> Means index and follow this webpage.
Place the robots meta tag in the <head> section of your webpage.
6. Open Graph Meta Tags and Twitter Cards
These tags make social media syncing easier.
Open graph meta tags promote integration between Facebook, LinkedIn, Google, and your website.
Here is a sample of how Open Graph tags look like in standard HTML:
<meta property="og:type" content="article" />
<meta property="og:title" content="TITLE OF YOUR POST OR PAGE" />
<meta property="og:description" content="DESCRIPTION OF PAGE CONTENT" />
<meta property="og:image" content="LINK TO THE IMAGE FILE" />
<meta property="og:url" content="PERMALINK" />
<meta property="og:site_name" content="SITE NAME" />
Twitter cards work in a similar way to Open Graph, except for Twitter.
Twitter will use these tags to enhance the display of your page when shared on their platform.
Here is a sample of How Twitter card look like in standard HTML:
<meta name="twitter:title" content="TITLE OF POST OR PAGE">
<meta name="twitter:description" content="DESCRIPTION OF PAGE CONTENT">
<meta name="twitter:image" content="LINK TO IMAGE">
<meta name="twitter:site" content="@USERNAME">
<meta name="twitter:creator" content="@USERNAME">
7. Header Tags
You can use header tags to change font sizes and signify information hierarchy on a page.
The heading elements go from H1 to H6. H1 is the largest and most important level, and H6 is the smallest and least important.
If you mark text with an H1 tag, you signify to search engines that it’s the most important text on that page.
8. Responsive Design Meta Tags for SEO
The final important meta tag is the responsive design meta tag, which is also called the viewport meta element.
Viewport meta tags allow web designers to configure how a page scales and displays on any device.
In the first image, the text is cramped and hard to read, and the image doesn’t scale well. In the second, both the text and the image fit the dimensions of the screen.
You can find the viewport element in the head section of your web page.
Use the following syntax to add a responsive design meta tag:
<meta name="viewport" content="width=device-width,initial-scale=1.0">
There’s one exception to the viewport meta tag rule: don’t use it if your website pages are not responsive, as it will make the user experience worse. You can use this tool to check whether your site is responsive.
