Google doesn't know you want to make noise when you capitalize your URLs. In fact, I think Google recommends lowercase URLs because technically case letters can create a different URL. But in general, lowercase or uppercase, it's the same thing. I agree that capitalization doesn't matter in SEO, and that it can only negatively influence you if you create mixed URLs, since they're harder to link to.
After reviewing the publication, we know that keywords and Google Adwords are not case sensitive. However, Google pays more attention to words and phrases with appropriate capitalization. For best results, you must follow the writing guidelines set by the English language. This will ensure the desired results in SEO.
But if you still choose to do the opposite, it won't affect SEO. In the previous post, Google's keyword tool combined non-capitalized keywords and capitalized keywords, but the search showed different competing pages resulting; therefore, Google considered them to be different keywords. For example, if someone searches for “Apple” and you use the keyword “apple”, the search engine will still show your ad. With Google Chrome, check the top SEO metrics instantly for any website or search result as you browse the web.
It doesn't matter if you search for the keyword in upper or lower case, the search engine will give you the same results. We have already discussed the benefits of capital letters and how sometimes searching in upper and lower case can yield different results (although it seems that this is no longer true). Obviously, in the last few months there has been a big shake up in the world of SEO and Google algorithms. Since my last post, I haven't been able to reproduce the same results on Google using capitalization or without capitalization.
You could attribute this to data centers, but not to inbound links, since the ones on this site are just for the company name and not the ideal search term. When it comes to SEO and capitalization, the best way to match content is to use the correct spelling, punctuation, and capitalization. Even if you look for a fire investigation in Georgia (only the capitalized state), you get 340,000 results and not the 2,870,000. Although it is believed that it can improve search results in some cases, even then search engines are not case-sensitive.
As you can see in the search results, people usually type the first letter of each word in capital letters, or camelcase, to make it easy to read, but that's not the case when it comes to the URL. I will try to set up a controlled environment and test it and report if there are really any differences in Google search results.
