Every Selling Platform, including eBay, has its ups and downs in traffic counts, especially while testing or installing new behavioral algorithms. Sales flourish when traffic is on the upside for awhile, then either slowly or suddenly just stops averaging up to two weeks. Not only do you lose potential sales profits, but also 'punished' in significant ranking growth, due to a lack of recent account sales activity.
The days of putting all your eggs in one basket is gone, unlessThere is nothing we can do to change it, except even out the sales playing field. While eBay has been feverishly adjusting their Selling Platform Algorithms (behaviors) to appease, attract and capture their share of online buyers, fact is, every selling platform has its traffic ups and downs. When DropShip Sellers receive traffic on the upside, sales flourish for a while then slowly move towards the downside, even as much as, in some cases, just stop for as long as a week or two. Every time this happens, Sellers lose out on sales and subject to working harder to regain the traffic/sales ranking visibility it once had achieved.
Again, every platform has its ups and downs.....and there is nothing we can do to change it, except even out the sales playing field, by diversifying, so when platform gets quiet , another is likely to pick up, creating consistent traffic and sales.
Every selling platform offers different features/restrictions to maintain control, however owning your own store and customer email where you control how you nurture it and if you treat it right is the most consist traffic you can count on. eBay is worth the time, but again, not without its flaws that cost you sales.
