It depends on different factors. Here in the Netherlands we use the “startpagina’s” in particular. Those sites can be seen as “directories” as we know them on USA sites.
Is it effective? Mostly not very effective, but it depends how much trust Google has in a specific startpagina. What I do first is use the open site explorer tool and check for Page Authority and those kind of interesting metrics.
If I see that the number is low, that’s a good signal to say that
site is banned of penalized by Google.
Futhermore, I check on rankings. Is the site ranking well in the SERPS?
If so, you probably get a backlink with some value in return, but that’s not always the case.
Fact is that Google don’t like those kind of link exchanges / submissions or low quality links in general. And with the Google Panda Update which will hit the Netherlands soon,
I would look for better ways to build links.
For example, try writing a few good, quality articles and ask webmasters who write about the same topic if they would vote for it by placing a link to it. Those type of links are of much higher value.
You should read this article about the Google Panda Update before making any decisions!
I was always interested to find the minimal efforts with the maximum of effects – methods.
Those links are not always the one that Google will love, certainly not with Google Panda.
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).
This will cause a ban or penalty when Google rolls out Panda in the Netherlands.
From your experience, the directories submissions are effective ?
Yes, sometimes. It depends on the quality of the site. However, there is a good chance that Google will penalize sites with lots of low quality backlinks when the new update is rolling out.
