Use the following guidelines:
- Content must be available on the first screen of the user;
- The best option is if the key phrases are placed, among other things, in the first paragraphs of the main content of the site page;
- Key phrases should be placed in the Title tags, H1-H6, since the occurrences of the page in these tags are more important than the matches at the bottom of the site page;

- Key phrases should be designed using the optimal font and size;
- Key phrases should be designed using the optimal font color;
- Key phrases should be designed using the optimal background of the font;
- Key phrases should be used in the anchor list of the page.
