Constantly I observe on sites the same mistakes considerably complicating promotion of sites in a network the Internet. I bring the list below, I hope, it will be useful for owners of resources.

1. Absence of a file robots.txt

The file contains recommendations for search robots on indexation of a site (more in detail about for what the given file is used, you can learn{find out} on page http://www.rambler.ru/doc/robots.shtml, for example). It is quite often necessary to forbid indexation of any pages or sections on a site, the file is necessary for this purpose and. However often the file simply is absent on the server, that at times results in very unpleasant to consequences. For example, to presence at base of search engines of pages with results of search on a site.

2. Mirrors of sites

Often copies of a site lay on several domains, in some cases search engines count such mirrors different. Host directive in a file robots.txt (for a Yandex) could correct a situation and a precise registration of links to internal pages of a site, however quite often the web designer about it forget. In a result there can be a situation when one search engine knows pages of one mirror, other search engine knows about the other mirror, and the third knows on slightly pages of one site and slightly another. I shall note, that process "perezerkalivanija" sites "back" at times can be rather long.

3. Incorrect answers of the server

It happens, that at attempt of users to address to nonexistent pages the server gives out to them instead of 404-th mistake, a code 200. Thus he lets know to search robots, that with page that's all right and her{it} it is possible to index. Similar pages hammer in an index search system, preventing correct indexation of a site.

Similar problems can arise and at incorrect job with redirects on sites. The user addresses to any page, it{him} "throws" on another (main, for example), however the server "overlooks" to give out 301 answer. In result the set of takes of pages breeds, the index of the search engine gets littered.

4. Absence of a map of a site

The map of a site not only allows users to be guided easily on a site, but also is healthy improves indexation of a site by search engines, especially if the structure of a site confusing or a site enough big.

5. Grain crumbs

It is essential to simplify use of a site by users introduction on sites of additional navigation, so-called ” grain crumbs “ will allow. Getting on the link from search engines on any vnutrennuju page of a site, the user at times has no opportunity to proceed{pass} to a level above, to see{overlook} other pages from the current unit. ” Grain crumbs “ are just called to simplify a life to visitors of sites. Additional navigation also simplifies to search robots a problem{task} of correct indexation of a site. In an ideal the structure of additional navigation should be such:

Main / the Name of the unit / the Name of subitem / the Name of page

At such structure the user can easily define{determine}, where particularly he is on a site and as him to proceed{pass} to a level above. Search robots also can use ” grain crumbs “ for construction correct ” a tree of a site “.

6. Absence of the text in the menu

Often it is possible to meet beautiful sites with the items{points} of the menu executed in the form of a picture. Nobody argues, it is looked very effectively, but whether it is effective? Text items{points} of the menu could improve considerably internal reference ranging on a site so, to raise{increase} efficiency of all promotion of a site.
