Basic Plus names are not visible in the main marketplace unless they have earned “enough” loves and likes in contests to become visible. Squadhelp does not reveal now what it takes for a Basic or Basic plus name to be visible in the marketplace. Instead, you get a message on your dashboard that says it qualifies and you need to click to take action. Once a Basic name is boosted to Basic Plus and visible in the marketplace, it does not receive a logo.
So, views in the marketplace do not count to my knowledge. Only likes and loves in the contests can cause a basic or basic plus name to be visible in the marketplace.
To your question about whether or not those names have any chance of being sold: the answer is 90% no. The way to get them sold is to use them in contests. Then, yes—UNLESS they are visible in the marketplace - then definitely yes.
The way this works in contests:
If you submit a BASIC name to a contest and it wins, you have to turn over the domain for only the contest prize. Basic Plus names (whether visible in the marketplace or not), come into a contest with the price listed, just like premium domains do. If you win the contest, you receive the contest prize and the CH then can buy the domain and you receive the difference. However, sometimes the CHs do not follow through to buy the marketplace name, in which case you receive the contest prize and can continue to try to sell the marketplace name to someone else.
I hope this helps and doesn’t confuse you. It is complicated!
