Thank you for your answer @Gebruiker2500. It’s very clear that the competition is not so powerful than on the Google.com but I was always interested to find the minimal efforts with the maximum of effects – methods.
In this moment it’s really time consuming to test these methods and after 2 months of web directories submissions, for example, to see that this method has no effect in rankings.
This is the reason because I want to know from you if the directory submission has some effects in rankings.
For example, on Google.ro, if I submit the website to 300 directories, the website can obtain the 11-20 position. If I submit the website to 300 directories on Google.com, the effect will be minimal (almost no effect = time consuming).
From your experience, the directories submissions are effective ?
But the link exchange ? But the blog comments / forum signatures ?
