I am newbie, I recently learnt about liking any post
No worries. I didn't realize forum ettique when I first joined either. Took a member or two to teach me that folks are spending their time responding, it might not always be what I want to hear, but engagement of any kind shows some type of effort acknowledgement.
Your initial question is a little confusing, as you say you want to learn about what's getting accepted brandable marketplaces. The answer you're looking for is likely more than just looking at newly published marketplace domains, as to the naked eye, it can be hard to determine which was a hand registration, and what was a premium investment.
Understanding you stopped registering names, and that you are a noob, your best bet would be to understand the differences in brandable domains (made up brandable domain such as Google, or two word brandable domains such as namePros) then start asking yourself what type of business could example domain be. If the intent is to have the name listed on BB/SH, unless you are super confident in the name, it might be best to see if BB/SH are accepting similar keywords. Each marketplace has their preferences, which includes being prone to accept/reject certain keywords or patterns.
Then, once you feel like you're starting to gain an understanding, and are finding similar marketplace type domains listed, you can hedge your strategy by submitting domains unregistered to BB/SH, and only register what gets accepted. This way, if BB rejects 50 of your submittions before accepting 1, it would only cost you $50 in submission fees +reg fee, opposed to 50 x regfee + $50 submission fees, only to end up with 1 bb domain and 49 rejects, especially if your attempt is to register less domains, yet still enter the brandable marketplace excitement. With experience, you can eventually drive that 1/50 rate down to 1/5 or better.
Another way to build a portfolio of marketplace listed domains is to buy marketplace listed domains from other domainers. This may be a little more expensive, but it will limit the amount you waste on rejects, if you're mainly looking to build a folio of brandable marketplace listed domains.
I spend a lot of time looking for available domains to submit to brandable marketplaces, likely surpassing the 10,000 hour mark, or at least having surpassed the 10,000 domains rejected at BB mark. Still, with all that practice, I utilize the unregistered submission strategy, to maximize my brandable marketplace domains, and limit my ownership of domains I don't have a sales strategy for. Even with 10,000+ rejections, this process has led to thousands of unregistered domains accepted and published on the popular brandable marketplaces such as BB/SH. Of course by not registering the domains before marketplace approval, you risk the best (usually just dropped) domains being registered before a marketplace responds with an approval, but that's the price you pay not to get stuck holding the rejected domain bag, if your intent is more marketplace domains, less rejects.
Two tips I can leave you with, is:
(1) This forum has a wealth of knowledge. It's hidden, and burried everywhere. The
brandbucket experience thread was very popular a few years back, and has over 300 pages of hidden gems dispursed throughout the evolution of BB becoming what it is today. There's also a personal favorite thread of mine that was started by the legendary
@Dnbolt called
brandable daily sales analysis. That thread is not as long as the brandbucket experience thread, but it's packed with moderate to advanced brandable domainer strategies, that if understood, could really open the flood gates to better understanding brandable domains, and/or the hunt that goes into uncovering them.
(2) If your goal is simply to practice learning what brandable marketplaces are accepting, I reccomend you start with submitting unregistered domains to squadhelp via their point based system. The point based system uses 10 squadhelp points per domain submission, and if accepted, SH will register and list the domain, and will pay you a percetage of the sale if squadhelp ever sells the domain. SH points are relatively easy to be acquiredfrom various sh tasks, but not hard to acquire. We have 50,000 sh points, as we use pay for SH coins so we (not SH) can register what gets accepted, but I assume our acceptance rate (submission quality) is more tailored to what SH likes than what yours is based on your inexperience. SH screenshot below in case you're not familiar as to how to submit domains for essentially free to SH, for practice, or otherwise a hedged investment where you get paid without having to put up any capital such as registration fees or coin purchases.
...
Additionally, you can always post availabe to register brandable domain names on namePros for practice purposes, and follow what other domainers like enough to register. It's not the SH/BB metric, but it checks the basic checkbox of example domain being worth at least reg fee to another domainer. Overtime, you can track your picks, to see if any end up on the brandable marketplaces, or later developed. Or if you registered a domain, and want feedback, you can try namePros appraisal section, maybe with a buzzworthy title such as, is my exampleDomain likely to get accepted at exampleMarketplace.
Lastly, If need be, If you or anyone reading this is ever looking for an opinion on a potential domain, feel free to DM me (or find you a trusted domainer friend, there's many domainers on this forum with a better domain eye than I) if it's unregistered, and I (or your trusted domainer friend) will give you some feedback without stealing your find. Sometimes it helps to get an unbiased or experienced second opinion. Nobody can predict with certainty if an available to register or recently hand regged domain will get accepted, but there is a general level of logic behind what has a good chance of acceptance, and what doesn't.
