Yes, SEO keywords are generally case sensitive. This means that the way you capitalize or spell a keyword can impact whether or not it appears in search results.
For example, if you are targeting the keyword “SEO services” and you use lowercase letters in your content, your website may not show up in search results when someone types in “SEO Services” with capitalized letters.
It’s important to note that there are exceptions to this rule, as some search engines may treat certain keywords as case-insensitive. Additionally, variations of a keyword (such as singular or plural forms) may also be considered when determining search rankings.
However, as a general rule, it’s a good practice to use consistent capitalization and spelling for your target keywords in order to increase the chances of appearing in search results. This can also help to avoid confusion or errors when analyzing keyword performance data.
