SEO keywords play a pivotal role in raising your online visibility. However, let's delve deeper and understand, what exactly is a keyword in SEO.

In internet marketing, a keyword is a word or phrase that individuals input into web browsers when they are trying to find a particular service, product or information. SEO heavily depends on the use of these keywords in ranking websites.

The power behind SEO keywords lies in their ability to associate what users are searching for to the content that is available on your website. Effectively using these keywords will help draw the right audience and boost the likelihood of leads.

Having established the concept of an SEO keyword, let's look at the ways to effectively use keywords. Enhancing the use of keywords demands a balance. You'll want to include relevant keywords to get the attention of search engines but without stuffing your content with them.

One way is to place the keyword in your content’s title. This not only helps in ranking, but also makes your content more relevant to the searcher's query. You should also think about using keywords in the meta description and headings of your website, as these are areas where search engines often look.

Moreover, it's critical to choose keywords that resonate with your targeted market. This means understanding how they communicate, their search behaviors and their wants.

To conclude, a well-chosen SEO keyword can be a connection between the user's search and your website's offerings. It's a vital tool in achieving success in the aggressive website world of digital marketing. However, as with all tools, using it correctly is the key to unlocking its full potential.
