It analyzes the top-ranking search results for a particular keyword and gives you comprehensive details on how to optimize your content to make it rank. 

Our favorite feature of Surfer is its SERP Analyzer. The SERP Analyzer gives you an in-depth analysis of the first page results of Google. It analyzes over 500 on-page signals to give you the needed SEO data. 

The analyzed data includes the ideal content length, density, and frequency of the target keyword, secondary keywords, number of headings, the structure of headings, ideal image count, number of paragraphs, and more.

Another feature, the Content Editor, has an in-built outline builder. With its help, you can see the titles and headings of top-ranking results in the same place and build your outline in line with the final optimized content. 

You don’t have to research the questions that your target audience is asking. The Content Editor gives you a section of “questions” to address based on the search intent.

Not only that,  it’s great for updating existing content, too. You can also audit and identify gaps in your published content with its Audit tool to make them rank higher.

The best part? 

It makes collaboration with freelance writers and the internal content team extremely easy. You can generate a sharable link to the Content Editor and share it with your writers to make the process easy, quick, and hassle-free for whoever is working on the project.

The Editor will score your content out of 100 based on how optimized it is. If it has a low score, you can make suggested changes and optimize your content even further. For example, it highlights broken links so you can ensure all the links redirect to web pages you want.
