How to do SEO text analysis by yourself with a tool

SEO analysis or semantic analysis of text online is to check the content for compliance with the requirements of search engine promotion. Except that these requirements have never been static.

A little history

Website SEO promotion emerged when competition online started to be a thing. Website developers began to study the algorithms of search engine results in order to find a way to be the first.

Texts at this stage had only one goal: to bring the customer to the site. It was easy to do: all you needed is to be among the first positions in the search results, which meant meeting the search engine requirements. No one bothered about content. It was a bunch of keywords and phrases because that was the criteria for a website page ranking.  

For anyone who visited those sites, this kind of content was awkward and unreadable. So in an effort to increase their popularity, search engines began to improve the algorithms for content analysis. Gradually the focus of attention shifted from keywords to the usefulness for the customer.

SEO today 

Today there is a distinct trend of “humanizing” content. Articles are written for people, not for search engines. The search results ranking has not lost its relevance, but now for every piece of content, there are separate analysis algorithms. No one will apply the same standards to the informative blog article and online store content.

To improve a website ranking, SEO specialists today need to take into account a number of factors, which we will talk more about below.

The requirements for the SEO text

Before you begin to analyze a text, an SEO specialist needs to make a list of requirements. But the selection of aspects to be taken into account should be approached with caution, since, depending on the subject, some requirements may be unrealistic or unachievable only to the detriment of the content in question.

Here is a simple example. A high keyword density in the news articles is unacceptable and indicates the author’s unprofessionalism. But it is much more difficult to reduce the keyword density of instructions and manuals without worsening the readability of the text.

1. The absence of plagiarism is probably the most common requirement for texts. The higher the uniqueness of the text, the better, but achieving the cherished 100% uniqueness is sometimes impossible. Take for example the legal content. Legal texts include many terms and quotes that are used in all similar resources. 

2. Relevance and usefulness. A good piece of content must be useful to the reader. You can’t check how relevant your text is to the subject matter; it’s a purely subjective assessment. However, requiring content writers to produce informative and factually correct content is a must.

3. Perception. Few people would want to spend a lot of time figuring out an incomprehensible wall of text. The majority of users who visit a website with this kind of content will leave it within seconds. To make content readable, you must make sure that it includes subheadings, bulleted lists, and, if possible, visual content.

4. No misspelling and other mistakes. To avoid arousing negative emotions in the reader, you should write clearly and competently. It wouldn’t hurt to run your texts through services that detect punctuation and spelling mistakes.

5. Completeness and transparency. Is information provided in your content grounded in reality? There are no text analysis tools that can answer that question. Your website visitors and customers, on the other hand, can.

6. Keyword density. This old trick of stuffing as many keywords in your content as possible is long outdated and now works against you. Search engines can detect over-optimization, see it as an attempt to influence the search results, and grant your website low positions in the ranking.

7. Commercial factors. This means all the information that will help the client to learn as much as possible about the company. They include contacts, phone numbers, price lists, delivery terms and positively affect your website position in the ranking. 

How to find the best text analysis software

Website content improvement is no less important than working with links. Internal optimization is great because it offers a lot of freedom. There is no need to negotiate with anyone, to check if link placements are correct, to have endless arguments with webmasters about anchor texts. Today, without an optimized text your success when dealing with search engines and competitors is unlikely.

Therefore, to help the optimizer there is software that analyzes the content based on a number of parameters, such as keyword density, keyword relevance, etc.

This text analysis software is mostly used by freelancers or small companies, i.e. those who cannot afford to hire programmers to write their own tools.

The text analysis tools you can find online are:

  1. Paid.
  2. Free.
  3. Universal.
  4. Multifunctional.
  5. Specialized multifunctional.
  6. Monofunctional.

Universal tools analyze the link, technical and textual components of the site. Monofunctional text analysis software evaluates websites based on multiple parameters within a single area (link, text, or technical). Monofunctional services analyze only one of the parameters.

When choosing text analysis software, pay special attention to the following parameters:

1. Interface usability

2. Speed and reliability

3. Functionality

  • Analysis of meta tags;
  • Title and meta-tag analysis;
  • Header analysis;
  • Quantitative analysis of website content;
  • Analysis of the frequency of key phrases and the accuracy of their occurrence in the document;
  • Keyword density analysis.

4. Additional features.


In conclusion, it is worth saying that not all of the text analysis tools are equally useful and not all have optimal functionality. This is because of the fact that many free services serve as a kind of advertising for the resources that created them. In order to fully and accurately analyze the text content on website pages, it might make sense to use paid services.
