IMO, all of these offpage SEO techniques and tools will forever remain questionable to you if you have no total idea how this things work and which one will not. SEO is a vast topic. One will work out but it does not mean the others will do the same so it depends on every SEO factors to consider. One day is not enough to absorb all of this so take one step at a time. Try to research and dig deeper into this on the internet and you will be enlightened.
