I did some extensive research on SEO softwares and I have boiled down to getting scrapebox. gsa, amr,article kevo. Now I dont know which ones to get because I can only get two. I want to know which are best for seo as of now. I will buy just one for now and the other later. I chose 1 time payment softwares for a reason also so if you have any suggestions please make sure they are one time payments.
