This software helps to build a relationship with customers which has great effect in increasing sales for our store as compared to other competitors who do not have this tool of customer engagement. I don't know if any but it's good enough to say about this tool. It works well. Nothing much to complain about yet, still exploring to find more features we would like from them. We're using linkious for my personal blog where i'm sharing recipes and articles through which people can easily connect with each other. So far it has been working perfectly fine for me because most users are looking forward to read such posts by clicking links given so they visit my website.
