I know, If reciprocal linking is related to the same niche, Then only it will make any benefit in terms of link exchange; But my point is, Do reciprocal linking is having any negative effect in terms of the impressions in front of the Google. I mean to ask, Shall we not consider this link building technique under natural link building. Thanks a lot in advance.
It depends, if the majority of your link profile is created with reciprocal links, you will definitely take a hit from Google, however a few natural reciprocal links that come from your websites within your own niche will be beneficial for sure.
