What would you do?..

I have had some mega xrumer blasts done for me recently for a site I opened about 2 months ago.

I am tempted to ping all the backlinks to help with serp promotion!

Would you say this would be a good idea or might send me to sandbox?

Is pinging acually useful?

I don't recommend to do massive pinging on backlinks especially if we are talking about a new site, unless you want to get your site sandboxed the fastest way.

depends on how many links. I would keep it under 2500 a day
