You’ve probably noticed that the built-in search tools on most websites often do a horrible job at helping you find the exact content you’re looking for on those sites.
For example, if you make even the slightest of a misspelling of a single word in your search term, the search will usually come up empty.
What’s more, most site search tools won’t suggest posts/pages from the site that are closely related to, but slightly different from the actual search term.
Google excels in situations like those, and that’s why I almost always use Google instead of a website’s native search tool.
