Why are not beneficial directory tools for SEO

hi friends pls tell me that Why are not beneficial directory tools for SEO....................

 

not sure what you mean. you find the directory tools not being beneficial or you need a directory tool that is beneficial?

 

i mean to say.... usually people not use directory tools for submit to directory.... why?
it is not not beneficial for seo? or it is effected of sites ranking?

 

HI,
If you submit site in directory manually that is much useful for the site.

 

Try to submit manually because it worth's a lot when you come to quality,so try to avoid using tools.
