Answer the Public

Type any keyword into this free online tool and you’ll get an extensive visualization of questions people have asked on Google using your keyword. This tool connects with one of the biggest recent additions to the Google search pages: Snippets.

On some search results pages, Google now displays Snippets. A snippet is a tab near the top of the page that highlights a common question related to the target keyword. When a user clicks on the snippet, Google connects them to a web page that answers that question explicitly. Being featured in a Snippet is a great way to generate organic traffic because Snippets are always near the top of the page.

With Answer the Public, marketers can write highly targeted articles that directly address questions that they know are being typed into search. This makes it more likely that their articles will be featured in Google Snippets.

Keyword Density Checker

Keyword density is an important factor that search engines like Google use to rank web pages. Digital marketers know that the Google Search algorithm looks at the density of keywords to understand the relevance of each piece of content. For each blog post, it is important to ensure that the target keyword is mentioned a sufficient number of times within the text. At the same time, excessive mentions of the keyword (a practice known as keyword stuffing) are discouraged.

This simple keyword density checker makes it easy to figure out how many times each keyword is mentioned in your article. You can paste in the text of your article and you’ll receive a list of the most frequently occurring one-word, two-word and three-word keywords in your article. For most content pieces, digital marketers aim for a keyword density of 2-5% for the target keyword.

Read-able is a useful tool for ensuring that your content is accessible for your target audience. When you paste your article into Read-able, it uses a proprietary algorithm to assign your content a grade level that corresponds to how easy it is to read and understand.

The average North American reads at an around an eighth-grade level, so if that’s your target audience, Read-Able will help you write clear and concise sentences that are easier for a wide range of readers to understand. If your target audience is college-educated, it’s okay to use longer words and complex sentences to convey meaning.
