Keyword density indicates the number of times a particular keyword or keyphrase appears in certain parts of your web page, including the title and body.
Ideally, your content should include as many relevant keywords as possible. However, doing so could mess up his sentence flow and he could end up reading unnaturally. This could eventually cause your customer to look for another site that they can read better.
The best search engines use search engine spiders to crawl the contents of the website and extract pages and websites with keywords that match the query. Spiders can tell if your keyword density is abnormally high, and your site will be reported to search engine administrators. If they find out that your website is just an avalanche of keywords with no useful content, your website could end up getting banned or blacklisted.
There are keyword density analyzers that are available online. These analyzers calculate the keyword density of your content. They work with different matrices, but in the end, they all tell you when you are using keywords too much. Generally, the acceptable percentage of keyword density for your entire web page is between 3% and 8% relative to all other non-keyword content.
Having the right keyword density allows you to search without sacrificing the quality of your text content. Although keywords are a lot of work for your website, the real revenue generator is relevant, well-written content.
When customers feel that you take the time to talk to them and address the things that are important to them (related to your brand or product), they will appreciate you more and reward you with their loyalty. And if they really like you, they will even tell their friends to visit you and check out what you have to offer.
