SEO parameters (Search Engine Optimization)
SEO is no exact science. Opinions change from a professionnal to another about certain criteria weights. Still, differences are generally pretty light.
The default SEO parameters proposed by HTML4SEO must be changed with caution. We recommend beginners not to change them. On the contrary, SEO experts can set them from their experience. To do so, click on My SEO parameters in the toolbar.
Then a dialog box pops up.
Current tab/Preferences
It is composed of 2 tabs : Current tab and preferences. The options are the same in both tabs. However, the parameters set in the 2 tabs do not have the same scope. In the Current parameters tab, they only last until the session is over. In the next session, they will be set to default again. Whereas in the Preferences tab, they will be saved between sessions. In the next session, they will be used as default settings.
Number of keywords and keyword density
The number and the density of keywords are both used by search engines to evaluate a web page revelancy toward a keyword. The keyword density seems more important than the number of keywords which must not be underestimated thought.
The number of keywords is the total number of times you can find a keyword in a text. The density is a percentage which measures the strength of a keyword in a text. It is the ratio between the number of keywords and the total number of words.
If a keyword appears twice among 400 words (number of keywords = 2, density = (2/400) x 100 = 0.5%), it is less important than if it appears once among 30 words (number of keywords = 1, density = (1/30) x 100 = 3.3%).
Once again, do not change the default settings if you are a beginner. Otherwise, if you are a SEO expert, feel free to modify the proposed values. To do so, move the sliding cursor to the number of keywords or density criteria you want to foster.
By default, the number of keywords is set to 4 and the density to 6, which corresponds to respective weights of 40% and 60%.
Changing this parameter, you will modify the audit results.
Tag weights
Search engines give a heavier weight to the words contained in some HTML tags. Once again, do not change the default settings if you are a beginner. Otherwise, if you are a SEO expert, feel free to modify the proposed values.
The HTML tag weights vary from 1 to 10. You can disable an HTML tag by unckecking it.
For example, the TITLE tag weight is set to 10 by default, as the text weight is set to 2. HTML4SEO will give 5 (10/2) times more importance to the words in the TITLE tag than the words in the text.
Changing this parameter, you will modify the audit results.
