I know the tool that help us to find the difficulty of a keyword to be acquired.But any tool that help us to know the effort that we must take ?
IMO, prediction of efforts like the time that will be taken to achieve Top 10 rankings will be difficult. We all know the things that can be done to achieve Top 10 rankings. But I do not know if there is a tool which gives info that to achieve Top 10 for a particular keyword, you need to build 50 backlinks or so. Because Google look much more things for a site to make it rank in Top 10 for the chosen keywords. If there is a tool,then can it be relied upon, will it be accurate? That's the concern. Its a good question though !
