1 Graphic header
Very often sites are designed
with a graphic header. Often, we see an
image of the company logo
occupying the full-page width. Do not do it!
The upper part of a page is a
very valuable place where you should
insert your most important
keywords for best seo. In case of a graphic
image, that prime position is
wasted since search engines can not make
use of images. Sometimes you may
come across completely absurd
situations: the header contains
text information, but to make its
appearance more attractive, it is
created in the form of an image. The
text in it cannot be indexed by
search engines and so it will not
contribute toward the page rank.
If you must present a logo, the best
way is to use a hybrid approach –
place the graphic logo at the top of
each page and size it so that it
does not occupy its entire width. Use
a text header to make up the rest
of the width.
2 Graphic navigation menu
The situation is similar to the
previous one – internal links on your
site should contain keywords,
which will give an additional advantage
in seo ranking. If your
navigation menu consists of graphic elements
to make it more attractive,
search engines will not be able to index
the text of its links. If it is
not possible to avoid using a graphic
menu, at least remember to
specify correct ALT attributes for all
images.
3 Script navigation
Sometimes scripts are used for
site navigation. As an seo worker, you
should understand that search
engines cannot read or execute scripts.
Thus, a link specified with the
help of a script will not be available
to the search engine, the search
robot will not follow it and so parts
of your site will not be indexed.
If you use site navigation scripts
then you must provide regular
HTML duplicates to make them visible to
everyone – your human visitors
and the search robots.
4 Session identifier
Some sites use session
identifiers. This means that each visitor gets
a unique parameter (&session_id=)
when he or she arrives at the site.
This ID is added to the address
of each page visited on the site.
Session IDs help site owners to
collect useful statistics, including
information about visitors'
behavior. However, from the point of view
of a search robot, a page with a
new address is a brand new page. This
means that, each time the search
robot comes to such a site, it will
get a new session identifier and
will consider the pages as new ones
whenever it visits them.
Search engines do have algorithms
for consolidating mirrors and pages
with the same content. Sites with
session IDs should, therefore, be
recognized and indexed correctly.
However, it is difficult to index
such sites and sometimes they may
be indexed incorrectly, which has an
adverse effect on seo page
ranking. If you are interested in seo for
your site, I recommend that you
avoid session identifiers if possible.
5 Redirects
Redirects make site analysis more
difficult for search robots, with
resulting adverse effects on seo.
Do not use redirects unless there is
a clear reason for doing so.
6 Hidden text, a deceptive seo
method
The last two issues are not
really mistakes but deliberate attempts to
deceive search engines using
illicit seo methods. Hidden text (when
the text color coincides with the
background color, for example)
allows site owners to cram a page
with their desired keywords without
affecting page logic or visual
layout. Such text is invisible to human
visitors but will be seen by
search robots. The use of such deceptive
optimization methods may result
in banning of the site. It could be
excluded from the index
(database) of the search engine.

7 One-pixel links, seo deception
This is another deceptive seo
technique. Search engines consider the
use of tiny, almost invisible,
graphic image links just one pixel wide
and high as an attempt at
deception, which may lead to a site ban. |
