It’s important to understand the difference between developing or designing for stock marketplaces and for other purposes.
If you look at big selling items, they all share one similarity, which is extensive options, features, layouts etc. Many also have robust and clean coding but fundamentally, a big % of buyers would never know the difference, and it is the versatility, functionality, and presentation which captures attention and crucially maximises an items appeal and relevance to the widest possible choice of buyers.
To you point using data counters as an example – this type of functionality does not render something useless and can of course be included. But approval is based on item quality, as well as market competitiveness, sales potential etc.
This is what makes finding more unique features that don’t already exist in hundreds of other items so important. Otherwise, the marketplace would flood even more than it already is which can only serve to drive down author earning potential and buyer experience and choice.
What would sell more –
A) a landing page like yours with good and well commented code and the same useful features as many other items, OR
B) a landing page template with multiple demos e.g. for an app, an agency, a resume, or other uses, and a choice of design layouts or technical features which are not seen on other items?
Look at something like this or this (chosen at random) - both are, while arguably not as well commented or cleanly coded as yours, are fairly well designed, with significantly more features and demos, etc. yet neither have barely any sales despite having been for sale of several years. What chance does something with less of the same elements have?
For what it’s worth, personally I would prefer more focussed templates that ae built with a purpose in mind, but that is not where stock success comes form.
