The simplicity of getting recommendations up quickly with just few lines code! We are able to get our product out faster than expected because we can use it right away without having any problems or downtime issues. I would like if there was an option where you could see how many users have already used your app before actually recommending something so as not to waste time doing unnecessary work but this feature isn't available at present yet. It's very easy to set up by anyone who knows basic PHP/MySQL which makes us more flexible about what kind of products they want their customers to be exposed too - whether big brands such as Nike etc., smaller niche businesses (e.g. coffee shops) or even small local retailers. This has helped increase traffic from search queries compared to other platforms which were previously difficult to rank well against them due to lack of targeting options. Our main focus now is SEO rather than generating sales.
