What is indexation
To index web pages, search engines use robots to fetch content from websites. From a search engine angle, a site must have 'index-able' content to appear in its index. This means primarily text-based content. An index can contain large or small portions of text, keywords, descriptions, classification elements, etc.
Understanding the role and limits of robots in web pages' indexation helps properly optimize. We try to clarify how to get best results through compliance with the rules applied by robots.
The following tasks imply that we have access to HTML coding, i.e. to the sources of the page. Under this condition we can optimize ourselves: the META data, descriptive tags attributes, headings ; set up a schema as needed. If the above HTML is dynamic, we can assist for the definition of the program configuration. Pricing
Minimal compliance rules
As a minimum, the basic rules that follows make it possible for robots to represent the content of a web page. The following tags are needed:
- META data tags: TITLE, DESCRIPTION and KEYWORD
- Descriptive tags attributes, such as IMG ALT and TITLE
- Headings tags, such as H1, H2 and H3 as needed.

Do you speak bots?
To compensate the inability of robots to index non-text ingredients and non-text file formats, a few methods are available: META tags By meta tags we mean tags that specifically carry content for robots which is not visible on the page., compliance with HTML rules, and schemas By schemas we mean a set of rules that allow to embed structured data in the web pages for use by search engines and other applications which are not visible on the page. For successful search engine indexation, applying these methods to improve the compliance with the rules followed by robots is a better road than attempting to modify the content by artificially stuffing keywords.
What about Keywords?
To a certain extent, the expression "search engine optimization" or SEO leads to a misunderstanding. Such optimization is not done in the interest of search engines, it is done in the interest of visitors to give them the best possible answers to their queries.
As long as we deal with textual content, keywords make the bridge between what visitors search in search engines and the content they can find in websites. Thus, keywords must reflect very precisely the content. Otherwise the experience will be deceitful for the visitor, as the "word" is found in the search engine resume but the website content does not really match it.
For the same reason, when dealing with visual or audio content, the keywords used to describe the content of the media must properly reflect its substance.
