How many backlinks at most can we get per week without going to thesandbox ?

Although the irregular intake of backlinks can seem suspicious and panic the algorithm to the point of getting a website pushed into the sandbox, there is no real known limit.

Indeed, Google teams always walk in the internaut shoes and it would make no sense to penalize a website that is under the influence of a big buzz.

So in my opinion, you should not worry about the quantity but more on the regularity.

If a website is used to receive hundreds of backlinks or more per week … In the logic of the algorithm, this rate would have to be constant.
