SEO is a vast topic. 

There goes a lot of things like On-Page Optimization, Off-Page Optimization, Technical SEO, image SEO, and many more. 

And a lot of questions also come along with SEO, the one out of which is – whether SEO Keywords are Case Sensitive or Not? 

So, let’s know the answer to this question.

The SEO keywords are NOT case sensitive no matter where you place them inside your content like –

Main Heading(H1), Sub-headings(H2, H3, H4, …), Title Tag, Meta Description, Image Tag;

-except for the URL of the page.

If might be already knowing this. But make sure we are on the same page, the SEO is a process to improve the visibility of a webpage on Search Engine Result Pages(SERPs) when a user searches phrases related to that webpage. We also call the phrases “Keywords.”

Now, let’s take a look to analyze all the areas of your content one by one where SEO keywords are important and you should place them there.

Main Heading or H1 Tag

The Main Heading of content comes under what we call the H1 tag.

It tells a reader and search engines about the main idea of the content or what the content mainly focuses on.

One important thing to keep in mind while placing the H1 tag is to only use it once inside content.

If you keep more than one H1 tag inside your article, it will confuse the web crawler, and your content won’t rank.

Talking about the Case Structure of the H1 tag, then it’s is NOT case sensitive.

Sub-Headings or H2, H3, H4, … Tags

Next comes the Sub-Headings, which come under the tags H2, H3, H4, and so on in the CMS.

As the name tells us, these represent the sub-sections under the Main Heading of your content.

For example, in our case in this content, the Main Heading or H1 tag is – Are SEO Keywords Case Sensitive? which is the main topic to discuss here.

And the Sub-Headings or H2 tags are –

What is SEO?, Main Heading, Sub-Headings, Title Tag, Meta Description, Image Tag and URL,

which all are related to our Main heading or H1 tag.

Coming to the Case Structure, H2, H3, H4, … tags are also NOT case sensitive.

Title Tag or Meta Title

The Title Tag or Meta Title is an HTML element displayed on the SERPs when a user searches the keywords for your content.

So it specifies the Title of your Web Page and tells a reader about your content from outside the webpage.

Make sure to make it as catchy as possible. Because it acts as a front door of your content and the whole journey of your reader starts from here only.

The Title Tag is also NOT case sensitive.

Meta Description

The Meta Description is an essential part while executing SEO. But Unfortunately, at the same time, though, people neglect its importance when doing SEO.

The Meta Description displays just below the Title Tag of a webpage, of course, on SERPs.

It lets you describe your Title Tag and is the second place after Title Tag, where your reader’s eye gets attention while skimming through the SERPs.

After creating a head-turning Title Tag, make sure you also provide some exciting stuff in the Meta Description. This will help to pull your reader inside your content.

The Meta Description is NOT case sensitive, similar to headings and title tags.

Alt-Tag

Also known as Alt description or Alt texts, Alt Tag is an HTML code or attribute provided to the image tag.

It describes the image uploaded on a webpage and also serves as an alternative text to that image for the search engine crawlers.

If an image fails to load on a webpage, then it appears in place of it. So it is also helpful for visually impaired readers, as it will help the screen-reading tools to describe that image.

Alt Tag has its importance in SEO. So make sure you also place your keywords in it while writing an alt tag.

The alt tag is NOT Case Sensitive.

URL or Web Address

URL or Uniform Resource Locator is also known as “web address,” It tells about the location of a web page on the internet.

The URL is created as a text alternative to the IP Addresses, which are in number form—defining IP addresses, function to help in communication between computers and servers.

The URL of a webpage has the following components in it –

Protocol, Domain Name, and Path indicating the sub-directory inside a website, and its essential looks like below –

protocol://domain-name/path

The URL of a web page is Case Sensitive.

But also note that the capitalization of URL in itself doesn’t affect the SEO.

If you are creating a URL for your webpage, then you can choose any case as per your choice. And it will neither help nor demote your page when indexed by the Search Engines.

But, as Google considers URLs to be case-sensitive, the problem in SEO will arise if we have the following situation –

Let’s say you have two web pages,

-home.com/test

-home.com/TEST,

and both are without canonical tag, so crawlable Google Search Engine.

As the phrases in the URLs are the same with the only difference in case structure, this will split the rank signals between both the pages. It creates a situation where you are self-creating duplicate content on your website.

The crawler, in this case, will get confused on which page to rank on SERPs. It may choose a page that you didn’t want to rank for.

So to avoid the above problem, choose to create only one type of URL, only lower case advisable to prevent confusion. And use that throughout your website.

If you have created and shared different case structure URLs in the past, use 301 redirects to send all URL clicks to your lower case URL.

So now, we know the answer

Above was an overview of all the prominent places inside and outside the content, which you should focus on while doing the SEO process.

So, we can conclude that the Keywords used in SEO practices can be written in any case – upper or lower.

URLs are case sensitive but using different issues will not affect its ranking on the SERPs. Also, it’s better to choose only lower case characters in the URL to make things simple.
