Group Reach Estimator

Groups × members × realistic visibility — what your posting schedule can actually earn in views and clicks every month.

Estimates use conservative visibility (~12% of members see a typical post) and click-through (~3% of reached) — real numbers swing by group activity and content.

Realistic estimate — actual reach varies with group activity, post format, and how well the content fits each group.

Reach scales with groups and consistency, not with flooding one group. Once a schedule is working, GroupBlaster keeps it running paced and on time — including groups where nobody would see a third identical post.

Ready to stop doing this by hand?

Done by hand: estimating what your groups can reach — GroupBlaster does all three in one pass:

  • writing the post once per campaign
  • spinning a unique wording for every group
  • sending it out paced and on schedule

Reach questions, answered

Members × a typical visibility share (~12%) × posts per month, summed over your groups; clicks apply a ~3% click-through on views. The fractions are deliberately conservative — better to under-promise than to sell reach a tool cannot deliver.
