Long-tail keywords are made up of three or more words. When someone searches on these terms, they are looking for specific content rather than just browsing.

By adding more words to your keyword list, you give yourself an edge over competitors who may be targeting fewer phrases in their campaigns.

For example, if you sell sneakers and want to rank for buy a sneaker, then entering sneakers would not be enough.

However, if you add other words like men’s sneakers, women’s sneakers, brand new sneakers, etc., then Google will know what kind of products you’re offering, making it easier for your site to show up in search results when those queries are typed into the search engine.

This tool is mainly helpful to those who aim at growing their brands through Google ads. So decide wisely as to which of these tools will best help you grow faster online.
