Meta Description Guide

This article will cover everything you need to know about the basics of meta descriptions. We will talk about what they are, why they are important, and how to leverage them for your website’s SEO.

What is a Meta Description?

A meta description is an HTML tag used to describe the content of a web page. This description will show up below the title and URL of your page as it appears in the search engine results. In order to remain visible within Google, your meta description should be kept somewhere between 140-160 characters.

Meta Description Example

A meta description for this blog post could be:

"When writing a meta description, keep it between 140 and 160 characters so Google can display your entire message. Don’t forget to include your keyword!"

Here’s an example of how that meta description appears on Google’s SERP:


Here’s an example of how that meta description looks in the page’s code: 

<head> <meta name="description" content="When writing a meta description, keep it between 140 and 160 characters so Google can display your entire message. Don’t forget to include your keyword!"></head>

Why are Meta Descriptions Important?

Since meta descriptions appear with your title and URL on the results pages, they have the power to help or hurt your results’ click through rates. 

In terms of your search result, your meta description has the most real estate (two lines of text compared to one line for the title and one line for URL), so take advantage of the opportunity to sell your website with a meaningful message to searchers.

Since the click-through rate on the SERPs is seen as a potential ranking factor, the best way to make your meta descriptions SEO-friendly is to write them with the intention of getting more clicks.

Think of your search results like a traditional ad in a newspaper or magazine. Classic print advertising used headlines and taglines to entice a person to call a phone number or travel to an address to buy a product in-store.

With your search results, your page title is your headline, your meta description is your tagline, and the URL is the address. Since a meta description is essentially a micro-pitch for a webpage, you should fill it with active language that will make people want to click on your result.

Tip #1: Include Your Unique Selling Point

You want to write a description that conveys your website’s unique selling point (USP). 

Think: why is my page specifically better than all the other pages in the results? 

Don’t be afraid to make an emotional appeal with your message. Emotional advertising has traditionally found a lot of success tapping into people’s feelings.

Let's look at an example: 


From this simple description in the SERP, we see this company can repair and install air conditioning (a needed service in Florida). More importantly, they "provide comfort and trusted advice when people need it most" — imagine your A/C is broke while sweating in a hot and humid area. Who do you trust? 

A study in 2014 conducted by the Institute of Neuroscience and Psychology at the University of Glasgow suggested that human emotion can be categorized into four main buckets:

  • Happy

  • Sad

  • Angry/disgusted

  • Afraid/surprised

This company used emotion the right way to pull in potential customers. Very smart. 

Tip #2: Appeal to an Emotion in 1-2 Sentences

Google gives room for about a 1-2 sentence (160-character) summary below every search result. So, in one to two sentences, your descriptions should offer a compelling reason to visit the webpage. Add a clear call to action, address an emotional pain point, or offer a specific benefit to visitors.

  • If it is too long, it won’t fit, Google will truncate it, and people will not understand what your site can provide.

  • If it is too vague, people just won’t care. There are always other results to click on.

You should aim to connect with a searcher’s emotion in two sentences or less. 

As one of the more important SEO basics, meta descriptions can help make your pages more relevant. It is also important to have unique descriptions for every page on your website. Our on-site SEO study found that nearly 30% of the sites had duplicate meta descriptions and 25% had pages with no meta description at all.

Meta Description Length: Make it SEO Friendly

To encourage clicks and bring visitors from search to your website, do the following with your descriptions:

  1. Aim for about 1-2 sentences (140-160 characters) long

  2. Include your target keyword

  3. Target an emotion

  4. Add a call-to-action to entice opening the link

  5. Avoid duplicate meta descriptions

  6. Make it meaningful and descriptive, matching your content

  7. Double check how it looks with a SERP view generator tool

Using Multiple Meta Descriptions for a Single Page

In May of 2020, Google's John Mueller answered a question about using multiple meta descriptions. He said, "So, if you’re including a second meta description tag on a page we will treat that the same as if you just extend the existing meta tag on the page... there’s no kind of bonus to using a second meta description tag on a page compared to just adjusting your existing one."

SEJ reported that John Mueller stated Google can handle extra title and meta descriptions, but that publishers should stick to writing a single meta description and a single title tag per page.

Generally speaking, you will find that most pages will only have one meta description and that instances of multiple meta description tags are generally down to human error. 

However, in some instances, multiple meta description tags are used deliberately. The reason for this is to give a search engine additional options when it comes to displaying meta information that matches a user’s search query.

Purposefully Using Multiple Meta Descriptions

The aim of their use is to match the search engine queries with an appropriate meta description tag, which in turn could help improve the click-through rate.

For example, at Semrush we might build a post that explores the various aspects of keyword research. Within this post we might look to target the following search terms:

  • “What is keyword research”

  • “Keyword research tools”

Naturally, these have two significantly different search intents but are inherently related to one another. The idea of having multiple meta descriptions is then to craft two separate descriptions that relate to each phrase.

Therefore, if a user queries “what is keyword research” search engines would display our result with the meta description tailored to the “what is keyword research” search query. Equally, if a user was to search for “keyword research tools”, the second tailored meta description would maybe be displayed.

It is worth noting that there is no guarantee that a search engine will adhere to picking your desired meta description so it is at your own risk to implement multiple descriptions.

How To Implement Multiple Meta Descriptions

The meta description is found in a page’s HTML source and so, therefore, adding an extra meta description to a page is dependent on the application you use to build the website.

To add multiple meta descriptions, you need access to the HTML pages of your site and the ability to edit and amend them.

A meta description tag is required to sit between the head tags in the HTML code, and for best practice, below the title tag of the page. For example:

<title>Title of the page</title>
<meta name="description" content="Enter description here.">

This will add one meta description to your page. In order to add multiple, you must repeat this process, adding a second meta description between the <head> tags. This would appear as follows:

<title>Title of the page</title> 
<meta name="description" content="Enter description one.">
<meta name="description" content="Enter description two.">

To maximize the effectiveness of multiple meta descriptions, they should reflect the search intent of the highest volume keywords the pages rank for or are trying to rank for. This will then give search engines the opportunity to select the most relevant meta description for the user’s search.

Should You Use Multiple Meta Descriptions?

Unless you are purposefully trying to influence the search engine results as outlined above, then it’s generally considered best practice to only include one meta description for each post created.

Within a page that you are optimizing you should include your target topics & keywords, whilst also ensuring the content is 100% unique and satisfies the user intent of the top queries you are trying to rank for.
