Thank you for taking the time to write that!
1. Got it! While super interesting, this is something that will technically require a lot of things in place, but, this might come sometime later after the launch. Already discussing this internally.
Again, this is a whole another thing in itself and Sparktoro does exactly this, maybe we could wourk out an api kinda thing to pull data
This is something that can be easily found out if the target website is using wordpress or a popular cms, but would fail miserably for custom websites
This is already on roadmap
Already on roadmap
The above sounds more "no" and less "yes", but we have got traffic, category of the website, global rank and category rank. This will instantly tell you what websites are worth your time and energy.
Gonna soon have a public roadmap for people to vote on features.
If you don't mind me telling, what price point seems fair for the product at launch, so for eg. What are 20 guest post opportunities worth to you? Analyzing which, you could have maybe 6-7 opportunities that are a perfect match for you?
