No sales for a long time

1. Only 2 words: "Batch upload".
Nobody can compete with ****ers uploading in one day more models than average designer can model in 5 years. Especially if on marketplace is no pre-moderation of models.

2. Usually similar statistic fluctuations depends on realisation of search algorithms. We can place the top quality stuff here, but it can be pointless until marketing "geniuses" still playing and experimenting with search methods and with sorting of results. Yes, all it sounds like "conspiracy theories", but at least it's looks true.

Thanks to every body your cordial opinions and suggestions. But 0 sales for last 7 months is not it matter of hopeless.

I noticed that since beggining of the year, my model views fell down dramatically, almost to half amount compared to previous year. Strangely, this didn't correlate too much with the sales, as i still sell about the same, maybe slightly less - it's hard to judge precisely, as sales tends to fluctuate very much. Still, it would be interesting to know the reasons behind lower views, unlike the sales, those numbers were very stable over the years and only recently they went down significantly.

Sales trends will go up and down from month to month, depending on how many models you have online and how often you add new models. It's not uncommon to see sales go down after a really good month, for example, then pick up again the next month, etc. I highly recommend not to dwell too much on how good or bad you are doing at any particular day or week, but just keep creating new quality content based on your history of sales and, of course, based on the trends and analytics you see across the markets.

That said, if there truly is a problem with sales such as a dropoff of more than 75% of your average sales trend over the past few months, then it may warrant some deeper investigation on your part to see what could be going on that is outside of your control.

I hardly make sales too, though I fault myself for not making more models

I agree with iterateCGI. Especially regarding smartphones or typical, everyday household products.

I believe your items are competing in heavily overcrowded category and new uploads of the same type keep added at incredible rate.

Probably need to study and smartly use the analytics tool (https://www.youtube.com/watch?v=xI_HpXuPWms). How to use analytics tool gets covered towards the end of this video.

Whatever you do, just stop spending time on work that is already available multiple times.
For example those smart phones, there are just so many phone there. If you can get the 3D model out before a new phone gets to the consumers then you probably gonna earn something on it for a few months and then competing manufacturer percents new phone model, etc. etc. After that the phone becomes just another phone in a big pile of phones.

Cabinets, tables, chairs, beds, the same thing, just do not expect to sell any of that unless you trow everything in one big pack and give it away for 60 dollars or something.

Maybe consider repackage it as Unreal engine assets or something?
There is a growing community of architects using Unreal engine for VR visualization.

How long is long time? I am no successful seller myself, but the two first month of this year have been standard though.

I have some problem -___-

My collection of models is pretty small but usually I have some sales. But this month I getting less and less sales so it's interesting for me too.
