Chapter 33. Widespread errors in optimization of sites

Graphic header

Often the design of a site includes graphic header. It means that a picture in all width of the page, containing as a rule a company logo or the name and any other information.

Do not apply the given method on your site. The top part of page is very valuable place where it is possible to place the important keywords. In case of a graphic representation this place vanishes for nothing.

Sometimes absurd situations are met: Header includes text information but it is made as an image for more attractiveness (the indicated text cannot be taken into account by searchers )

It is better to use a combined variant – graphic logo exists upwards of a page but not occupy all width. The text header with key words is located in remained part.

Graphic navigating menu

The situation is similar to previous point. Internal inks of your site must include also key words
It gives advantage in time of ranking. If navigating menu is made as graphic for more attractiveness, searchers will not be able to take into account the text of links.
If you refuse graphic menu, do not forget to supply all images with tags ALT.

Navigation carried out through the scripts.

In certain cases navigation on a site is carried out through use of scripts. It is necessary to understand that searchers cannot read and execute scripts. Thus, the link specified through a script will be inaccessible for search system and the search robot will not pass on it.

In such cases it is necessary to duplicate necessarily links in the usual way for navigation on a site to be accessible for all – both for your visitors and for robots of search systems.

Session identifier

It is accepted to use the session identifier on some sites. It means that each visitor at calling on a site receives unique parameter &session_id= which is added to the address of each visited page of a site.

Usage of the session identifier allows collecting more conveniently statistics about behavior of site visitors and can be used for some other purposes.

However, according to a search robot, a page with new address is a new page. At each calling on a site the search robot will receive the new the session identifier visiting the same pages, as earlier, will perceive them as new pages of a site.

Search systems have algorithms of mirrors and pages with similar contents «Gluing». Thus sites used session identifiers will be indexed. However indexation of sites can be done incorrectly sometimes. Thus it is not recommended to use session identifiers on a site.

Redirects

Redirects make more difficult site analysis by search robots. Do not use redirects if it is not necessary.

Hidden text

Hidden text usage (text color matches background color, for example white on white) allows overloading with needed key words not breaching of logic and design of a page. Such text is not visible for visitors but successfully is read by search robots.

Usage of such methods of optimization can lead to ban of a site – forced exclusion of a site from the index (data base) of search system.

Links with one pixel

Usage of graphic images-links in the size of 1*1 pixel (that is actually invisible to the visitor) also is perceived by search systems as attempt of a deceit and can lead to ban of a site.

The list of the essential errors in internal search optimization and site development is given below. This list is conductive to impediment of effective site indexation by search robot. You may learn it and then it can help you to eliminate errors.
