Some Common Mistakes In SEO


There are some common mistakes which we include in our SEO process, avoid these mistakes to effectively run your SEO campaign.

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 cannot make use of images. 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.

Script navigation

   Sometimes scripts are used for site navigation. As a seo, 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.

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.  If you are interested in seo for your site, I recommend that you avoid session identifiers if possible.

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.

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.     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.
