Keyword Usage

This section tells you how your rivals use your target keywords throughout their webpages to get them to rank. SEMrush compares your usage of the keyword (keyword density) to the average usage between your rivals (the pages on the first page of Google). You’ll see if it’s used in their body, title, H1 or meta description in the first table. You can see the actual list of rivals we analyzed with the link under the SERP column. The “Keyword phrase usage” table at the top indicates the density of this keyword and the “Keyword Occurrences” table at the bottom indicates the actual number of times the keyword appears in the text of the webpage.
keyword-usageThe Word usage table shows the density between each word that makes up the target keyword phrase. If you’re targeting a long tail keyword, this will show you how often each word from the phrase appears on your webpage.

TF-IDF stands for term frequency-inverse document frequency and is a way of measuring how important a certain term is for the comprehension and subject of an entire document. Basically, it tells you how important the target phrase is based on how frequently it is mentioned within the set of text. You can compare your TF-IDF score to your rivals average and also rivals max here.

Semantic Analysis

The semantic detailed analysis shows you the top words and phrases that are used by your rivals and are semantically related to the target keyword. If you need help brainstorming the right words to use in your content, this is a great place to get started.

semantic-analysisThe semantically related words and phrases are listed in this table in order of the number of rivals that used the word/phrase in their content. If all of you rivals used the same semantically related phrase, you will see that phrase at the top of the table.

If your webpage is using this word/phrase, you’ll see a checkmark in the “You are using” column. If you aren’t using some phrases that are popular with your rivals, you should consider expanding the writing on your webpage to include these words/phrases.

backlinks-analysisIn this Detailed Analysis, SEMrush aggregates the backlink profiles of your URL’s top rivals and shows you the referring domains that are shared the most among the top 10. By default, the referring domains are listed by the number of your rivals that the domain is linking to. You can sort the table by Domain Score, You (whether or not your URL has the backlink), and the name of the referring domain.

Click on the number in the “Rivals” column to see where the link to your rival is coming from. If you see referring domains in this list that many of your rivals have backlinks from but you don’t, you should attempt to acquire a backlink to boost your page’s SEO.

Content Length

content-lengthHere you can compare how the word count of your webpages compare to your rivals for each target keyword. If you see that your pages have much less content compared to your rivals, it could be an opportunity for you to expand your content with more helpful information to compete with your rivals. Your rivals average word count will be shown by default, but you can click on the keyword to expand the list and see how many words are on each rival’s page.

Video Usage

video-usageThis analysis identifies the presence of an embedded video on your rivals’ pages. For each page ranking in the top 10, it will be noted with either “has video” or “no video.” Take note that your current ranking will be listed at the end of the row if you are not in the top 10.

Readability Analysis

readability-seoThis analysis will compare the readability score of your content to your top 10 rivals. Please note that a higher score indicated easier reading level and a lower score indicates more difficult. We calculate these scores in a similar fashion to Flesch-Kincaid. If you want your webpage to compete with your rivals, make sure that it does not have a drastically lower readability score. Otherwise, users and search engines will prefer your rivals more user-friendly content to yours.
