SEO: How to Analyze a Website's Content and Extract the Top Keyword Phrases

In this tutorial, we will demonstrate how you can use InfraNodus to analyze the content of any website. This can be very useful because you can get both an overview and also discover the structural gaps in your content that you can use to generate new ideas.  

This approach can also be used to improve your search engine ranking through better understanding how your website looks to search engines. Finally, you can also study competition this way.

Step 1: Open the URL import page

Step 2: Add the URLs of the website(s) you want to analyze

List the URLs of website you'd like to analyze. If you want to analyze several URLs, please, list them separated with a space: e.g. https://infranodus.com https://noduslabs.com 

If you want to analyze a whole website, you need to manually add all the pages from that website. In order to get all the pages, you can either use your own site map or add the list of the pages you're interested in manually. You can also use a tool like Screaming Frog SEO Spider to extract all the URLs from a website automatically. A free version of this tool can crawl through up to 500 pages of a website. You can then export the list of the URLs as a CSV file and copy and paste them into the URL analysis box below.

Step 3: Advanced Import Settings

Using the advanced import settings, you can specify:

1. the elements which should be analyzed from every page in the list above (e.g. #elements or .classes on an HTML page).

2. to analyze only the headers (H1 to H6) on a page (for SEO and HTML analysis)

3. to use the page titles as categories — this way if your pages are relatively large, you can filter them in the graph visualization and see the content only for the pages you select. 

Step 4: Visualize a Website's Content

The text content of the URLs you added into the list will be visualized as a graph, as shown below.

The bigger nodes show the most relevant terms, such as 
• graph

• text

• network

in this case. 

The Topics in the Analytics panel provide more detailed information on the topical clusters present in the website's content:

• network text infranodus

• graph create node

• gap idea discourse structural

• study market review

We get a clear idea of what the website is about and how a search engine sees it.

Step 5: Improve the Content, Promote the Website

As the next step, we can analyze what are the most popular search queries that bring the audience to this website using the tools like Google Webmaster Console or Ubersuggest. If we compare it to this graph, we will see the parts of the content that we need to promote better.

At the same time, using the graph above, we can identify some topics that we'd like to be more visible. For example, "text mining",  "data mining", "data visualization" are completely underrepresented in the example above, yet, they are highly relevant. This means that when we create the new content for that website above, we will focus on the semantic core around "text mining" and "data mining" and try to create more content like this.
