The term keyword analyzer refers to tools that provide various functions for analyzing keywords. This article lists some of these features.
keyword density analyzers analyze the frequency of occurrence of a certain keyword in a text or on a web page. For this purpose, the frequency of occurrence of the keyword is set in relation to the total number of words of the text / website. If the keyword occurs 5 times in a text of 100 words, the keyword density is 5%. This analysis can for example be used by checking the SERP for a specific keyword, and then analysing the content of the pages of the competitors to determine their keyword density. This way, the ideal keyword density for the analyzed keyword can be derived.
However, it must be mentioned that the keyword density is not an official ranking factor and that over-optimization of the keyword density can look "spammy" and even lead to worse rankings.
This type of keyword analyzer offers a wide range of analyses for a specific keyword. For example, MOZ's keyword explorer examines the SERP for the keyword entered, displays suggestions and related search terms as well as mentions of the keyword on the web.
This type of Keyword Analyzer is especially interesting for advertisers, as it allows them to analyze the performance of their paid search keywords more accurately or automatically using various metrics in order to improve campaign performance or save costs. This type of analyzer can also be used to research and evaluate new keywords for the paid search. An example of PPC Keyword Analyzer is WordStream.
This kind of Keyword Analyzers discovers pages on the web that use a specific keyword. SEOs use this information in order to find promising and relevant backlink sources.
Many keyword analyzers are available for free on websites. You can either enter a URL for the review or text can be entered directly into a text box and edited live. The feedback is accordingly fast.
Results may vary in scope. One option is a display of terms that occur a lot and their frequency in the content. Alternatively, keywords can be entered, for which you want to analyze the keyword density. More complex analyzers also take the HTML code into account and provide additional feedback on keywords in title and meta tags and other code elements. In addition to the number of occurrences and the keyword density, excessive use of keywords will be alerted. Keyword stuffing can be considered spam by search engines.
Larger SEO tools often include suitable test options, because the functions of a keyword analyzer are a basic element of keyword optimization. If in addition to the keywords, links are reviewed as well, it’s considered a page analyzer.
A keyword density analyzer enables you to get a quick overview of the distribution of terms in existing content. This data allows you to make specific modification to the text in order to increase the keyword density. Care must be taken to always ensure that the density is not so high as to result in keyword stuffing. It is also important that the text remains readable for visitors. If it no longer reads fluently, there is a risk that visitors will leave the site early.
