For example, a weight-loss website can identify many keywords: weight loss methods, how to lose weight, fast weight loss, weight loss in winter, weight loss products, healthy weight loss, weight loss network, weight loss and weight loss methods.
So how do you determine the keywords? There are three points involved here:
Relevance and density of keywords. Yes, "slimming" and "slimming" have the same meaning, but if the word "slimming" rarely appears on your website, the search engine thinks that "slimming" has nothing to do with your website, and you won't get the ranking of "slimming". The keywords you have identified must be mentioned frequently on your website. Unfortunately, when children searched for "100,000 whys", the search engine ranked my site "100,000 whys of SEO" on the first page, which should be a mistake of the search engine.
Search frequency of keywords. In the sense of China people, we think that "fast diet" and "fast diet" should be the same. However, search engines don't think so. According to Baidu's data, the "fast diet" is searched about 300 times a day, while the "fast diet" is searched almost zero every day.
Competitors of keywords. For example, the keyword "lose weight", although the daily search volume is tens of thousands, but its competitors are relatively mature, small stations are not easy to match.
