(3) Key words in the Title tag of the page’s code: fundamental is that the title of the page contains the or key words that we’re optimizing. The same length should be between 10 and 60 characters long and should not contain special characters. (4) Keywords in the Description metatag of the code of the page: although it is estimated that Google ignores its content to index a site, it is the description that appears on our site in a search result. It should contain less than 200 characters. (5) Keywords in the Keywords metatag of the code on the page: it should contain less than 10 words, and each word must appear somewhere in the body of the web page, so that Google does not penalise us for irrelevance of the keyword.
