Now i can see some traction (traffic increase weeks by weeks).
I have a list of around 500 url from profils / Blogs comments / web 2.0 (no and ********) many of them are DA between 70 to 96.

My questions is:
- At what rythme should i create thoses backlinks ? 1 per day, 1 per week ?
- My blog are in french, but some profils are english it is worth to do or only french profils.

Thank you in advance for your reply,
Just decide on a realistic pace for you and stick to it. Is one a day something you can realistically stick too?

If you can do 1 a day and they are good links it will certainly help you a ton! .. That being said if 1 a week is more realistic go with that.
