In information technology, case sensitivity (case sensitivity in English), describes the ability of a program to distinguish between upper and lower case in searches, URLs, etc.
Importance for searches
Google's search engine treats search queries as case insensitive and interprets requests as lowercase. An example to illustrate this could be the following: "nelson mandela", "Nelson Mandela" and "NELSON MANDELA" would return the same search results. For certain searches, it would be important whether the letters are lowercase or uppercase.
An example will show the problem that could arise: when searching for "Ram" (Hindu deity) or "RAM" (short for Random Access Memory) the search engine cannot correctly differentiate and interpret the terms due to lack of sensitivity to upper case and lower case. Google plans to introduce a "case sensitive search" in the near future to solve this problem and be able to interpret searches in the proper context. This may mean that case-sensitive URLs will be important.
Importance for domains and URLs
Domain names are generally case insensitive, which means that the PC reads lowercase domain names. The remaining address (URL) is case-sensitive depending on the server settings. A web portal is hosted on a server that constantly processes server queries and bounces through the pages referenced in the URLs. Servers with Windows operating systems do not consider case sensitivity. All URLs (lowercase or uppercase) are translated to lowercase. For example: the URL "en.ryte.com/the-urls- are case-sensitive.htm" and the URL "en.ryte.com/the-URLs- are case-sensitive.htm". as the same url.
In contrast, a server based on a Linux or Unix operating system will interpret uppercase and lowercase or case-sensitive URLs differently and treat them as unequal addresses. Example: "ryte.com/TipsandTricks.html" and "ryte.com/tipsandtricks.html."
As a webmaster, it is recommended to educate yourself about server-side case-sensitivity before choosing a web server.
Canonical label
You can also solve the case sensitivity problem with canonical tags. If the web server does not handle case-sensitive URLs, you can direct the URL to the original URL using canonical tags, thereby directing the search engine to where the original content is located.
