What are keywords?
In SEO, keywords are the words and phrases that searchers enter into search engines to find what they’re looking for. On the results page, the search engine returns relevant websites and articles that contain those keywords.
SEO professionals research the best keywords for their clients’ websites—keywords that will get the site ranked high in relevant search engine results pages (SERPs). But before they can do that keyword research, they need to understand what their client’s website is about and who their target audience is. Once they have that information, they can start their keyword research.
There are a variety of tools SEO professionals use to find keywords. Some of these tools are free, like Google AdWords Keyword Planner, and some are paid, like Moz’s Keyword Explorer. These tools allow SEOs to see how many people are searching for certain keywords, how difficult it would be to rank for those keywords, and more.
Once SEO professionals have a list of potential keywords, they need to determine which ones will be the most effective for their clients’ websites. They do this by taking into account a variety of factors, such as the competition for the keyword, the search volume for the keyword, and whether the keyword is a “long-tail” keyword or a “short-tail” keyword. Long-tail keywords are more specific (and usually less competitive) than short-tail keywords. For example

How to choose the right keywords for your website
There are a few things to consider when choosing keywords for your website. First, you need to think about what your website is about and what kind of audience you’re trying to reach. Once you know that, you can start brainstorming a list of potential keywords.
Try to be as specific as possible when choosing keywords. For example, if you sell women’s clothing, “dresses” would be a good keyword. If you’re targeting a more specific audience, like plus-size women, then “plus size dresses” would be a better keyword.
Once you have a list of potential keywords, it’s time to do some research. Use a keyword research tool like Google AdWords Keyword Planner or Moz Keyword Explorer to see how often people are searching for each keyword and how much competition there is for each keyword.
Choose the keywords that have a decent amount of monthly searches and low competition. These are the keywords that will help your website get found in search engines and drive traffic to your site.

The difference between short-tail and long-tail keywords
There are two types of keywords in SEO: short-tail and long-tail. Short-tail keywords are generally one to three words in length, while long-tail keywords are four or more words.
Short-tail keywords are more general, and thus have greater search volume. However, they are also more competitive, as they are less specific. Long-tail keywords are more specific, and thus have less search volume. However, they are also less competitive, as they are more targeted.
To decide which keywords to use for your website or blog, you need to Balance between the volume of searches and the level of competition for each keyword.
