Another fundamental thing to consider is avoiding domain names that are almost similar to another website's domain. For instance, where there is a domain like jobchecker.com, you shouldn't buy a domain that is jobcheckers.com. Even if you have added an s making the name gain some plurality, the name is too similar. There are other instances where a person might consider hyphenating the name or even adding some prepositions. In order to make your domain name unique and safe, you should consider buying these hyphenations as well as the prepositions and whenever a person feeds them on the search engines, they will direct them to your website.
