If you are interested in gTLD domains, you should first look at the gTLD list.

The extensions with a high renewal cost #

Many domain extensions have high renewal costs, which makes them not a good choice for investing in domains. You can register a .store domain for $2, but renewing it will cost you $50. Examples: .sucks, .sexy,and .diet.

In many gTLD extensions, “Premium Domain Renewal” is one of the most common high-cost renewal options. These can often cost up to ten or hundred times the standard rate for registration and renewal, meaning that if you register a domain with one of these extensions, you may be spending more than necessary on your domain in the long run. Examples: The renewal cost of Apple.xyz is many times more expensive than Apple123.xyz.

Premium domain extensions are typically owned by registrars, and they use them to maximize their profits. This means that prices are usually much higher than the standard renewal cost. For example, .com domains usually renew for around $10 per year, but some premium domains in other extensions can cost upwards of $100 or even more. A major part of “hot keywords” is excluded by registries from regular aftermarket, and the renewal fee on those names can be even in the five-figure range.

When selecting a domain extension, it’s important to consider the cost of renewal. If you plan to buy domains for long-term domain investment, going with one with a lower renewal cost may make sense.However, if you’re only planning on using the domain for self-development or for a short period of time, then a premium domain extension might be a good option.

TLDs with low registration volume #

When choosing a domain extension for domaining, it’s important to consider the popularity of the domain. Extensions with low registration volumes are usually not the best choice, as they tend to be overlooked and forgotten. For example, the .voting extension only has 108 domains registered, which is much lower than the other most popular extensions. Low registration volume implies that there are fewer people using the extension, and therefore less chance of someone else having the same domain as you. This can be beneficial in terms of avoiding trademark infringement, but it also means that there won’t be as much visibility for your domain. If you choose an extension with low registration volume, make sure you are the website developer instead of the domain owner and also take steps to increase visibility, such as optimizing your website for search engines and utilizing social media platforms. Examples: .rich, .protection,and .lotto.

Most Abused TLDs like .surf and .rest #

Some domain extensions are more likely to be associated with spam, scams, or phishing sites, which can make them less desirable to use. You can check spamhaus for more info. For abuse-prone TLDs, the list is long and unfortunately growing. Among them, .surf and .rest have been especially popular for criminal activities. The .cn TLD has also been abused heavily in recent years, as well as .ml, a ccTLD from Mali, West Africa.

It is recommended to stay away from TLDs like these unless you are willing to invest in an extensive security and monitoring system for your domain name. The costs of such systems will far outweigh any benefits that come with using one of these highly abused TLDs.

Far Away from Domainer’s Hype like .vip & .mobi #

There are some TLDs domainers hype that you should stay away from. These include .vip and .mobi. While they may seem like interesting choices, they can often be overhyped. It is the domain extensions to avoid lessons from real money. 

TLDs with No domain sales #

For domain extensions, there are a few that are notorious for having no or extremely limited domain sales. This means that the chances of getting a good return on your investment when registering a domain with one of these extensions is slim to none. Some of the most common of these extensions include .dentist, .plumbing, and .study.

While some people may be tempted by the low registration cost associated with these extensions, it’s important to remember that there are virtually no buyers for domains registered with them. Not only will you be out of pocket for the initial registration fee, but you’ll also have to renew it every year and face the risk of the domain being used for malicious activities.
