It shows which search engines are case-sensitive, along with statistics that show that 80% or more of people search in lower case letters. Google doesn't know that you want to make noise when you use capital letters in your URLs. In fact, I think Google recommends lowercase URLs because technically uppercase and lower-case URLs can make URLs different. Search engines like Google treat all keywords in a similar way, regardless of whether they are in lower case, uppercase, or a combination of both.
Notice that the results are the same. Google doesn't see upper or lower case letters in your search terms. It's best to know how keywords should be used in uppercase and lowercase letters so as not to unintentionally hinder a website's SEO efforts. When trying to stay relevant, website administrators often wonder if the distinction between uppercase and lowercase letters matters to search engines.
SEO keywords aren't case-sensitive, which means you can use uppercase letters, lowercase letters, or mix them in any order, as long as they match what you want others to find. Google, the world's most popular search engine, isn't concerned about the distinction between uppercase and lowercase letters as a matter of SEO. SEO stands for search engine optimization and is the process of getting more organic search traffic to your website. When entering an Internet address in a search bar, capital letters may be required for the address to be valid.
Depending on the trends in what people are looking for, the algorithm would show different pages of search engine results; for example, if people were talking about the actress from the movie “Precious”, the results of the term precious would probably result in that result. However, you should be careful about using these words, as some search engines may consider them spam. When deciding which form to use, consider which variant users can enter into a search engine and be sure to configure your site accordingly. However, the second, more realistic answer may also be that it distinguishes between upper and lower case letters depending on the search engine used, or even the specific website in question, as well as its content as a whole.
This is because Google or most search engines would divide ranking signals between the URLs through which the website can be accessed. So if you're looking for something like Britney with three t's, Spears, Google automatically corrects the error. The case of keywords will have absolutely no influence on the search ranking and, consequently, on their position in the results of the search engine page. However, these same complex algorithms are likely to emit different results when searching for the term Precious rather than precious.
The problem with this is that these repetitions can make a search engine's spam detector work, especially when it comes to phrases.
