How do I allow crawlers?

Are you talking about Google first click free feature?

hello, I dont know the first click feature, however I’m talking of the simple googlebot crawler that index our pages, as of all the other crawlers that are being denied access to our content.

It would be very important to allow search engines index our content and present it as “answer” in search results so that we can use the more tag to show a teaser and ask for user registration and/or payment if we want a paid membership.
