2.1.3 Keyword density and seo
Keyword page density is a measure of the relative frequency of the word in the text
expressed as a percentage. For example, if a specific word is used 5 times on a page
containing 100 words, the keyword density is 5%. If the density of a keyword is too low,
the search engine will not pay much attention to it. If the density is too high, the search
engine may activate its spam filter. If this happens, the page will be penalized and its
position in search listings will be deliberately lowered.
The optimum value for keyword density is 5-7%. In the case of keyword phrases, you
should calculate the total density of each of the individual keywords comprising the
phrases to make sure it is within the specified limits. In practice, a keyword density of
more than 7-8% does not seem to have any negative seo consequences. However, it is not
necessary and can reduce the legibility of the content from a user’s viewpoint.
2.1.4 Location of keywords on a page
A very short rule for seo experts – the closer a keyword or keyword phrase is to the
beginning of a document, the more significant it becomes for the search engine.
2.1.5 Text format and seo
Search engines pay special attention to page text that is highlighted or given special
formatting. We recommend:
- use keywords in headings. Headings are text highlighted with the «H» HTML tags.
The «h1» and «h2» tags are most effective. Currently, the use of CSS allows you to
redefine the appearance of text highlighted with these tags. This means that «H» tags are
used less than nowadays, but are still very important in seo work.;
- Highlight keywords with bold fonts. Do not highlight the entire text! Just highlight
each keyword two or three times on the page. Use the «strong» tag for highlighting
instead of the more traditional «B» bold tag.
2.1.6 «TITLE» tag
This is one of the most important tags for search engines. Make use of this fact in your
seo work. Keywords must be used in the TITLE tag. The link to your site that is normally
displayed in search results will contain text derived from the TITLE tag. It functions as a
sort of virtual business card for your pages. Often, the TITLE tag text is the first
information about your website that the user sees. This is why it should not only contain
keywords, but also be informative and attractive. You want the searcher to be tempted to
click on your listed link and navigate to your website. As a rule, 50-80 characters from
the TITLE tag are displayed in search results and so you should limit the size of the title
to this length.
