Keeping your domains under a single registrar such as Uniregistry is a great way to always ensure they are in sync with your records. Uniregistry is a mature domain registrar focusing on domain investors with portfolios of any size, and they provide management tools that quickly perform their intended functions.
Managing your domain portfolio can be a complicated task; its complexity scales up as the number of domains under management increases.
Simply put, the more domains you own, the harder it can get to keep track of your daily operations on them. From expiration dates to acquisition costs to inquiries, you need good tools and a dependable process that doesn't "choke up" when more domains are added.
Luckily, the Uni Market offers you the ability to group domains into separate portfolios, so consider the initial task of moving existing domains into new portfolios as a one-off "waste" of your time. Sure, it might take an afternoon or a few days (depending on how many domain names you own), but once completed, you won't have to worry anymore.
By organizing your domains into distinct groups, you can decide what to do with them. For example, grouping together a particular niche of domains about cryptocurrencies and the blockchain helps you manage developments in that respective market. Or, if you'd rather group domains depending on their function, e.g. geographical terms, you can present them later as one single set of geo-domains, leveraging their function, value, and usage.
Your domain portfolio management should not end there, however. It's important to remember that the entity listed as the domain registrant is the ultimate "owner" of the domain. If it's you personally, or a corporate entity, the person or company is the domain's registrant respectively. At times, there are good reasons to place domains under different entities that you own and operate.
For example, let's say that you have decided to form a company that curates news and produces hyperlocal articles. Suppose you have secured several dozen domains that target cities and regions with matching keywords. It's a great idea to form an entity, perhaps an LLC, that handles just that part of your domain portfolio—both the business function and the domain ownership.
There are two reasons for this type of domain portfolio splitting: practical reasons and legal reasons.
The first reason is obvious, and it's all about de-cluttering your domains and being able to perform functions easier. The second reason is equally important, and it's related to separating these domain assets from the rest of your portfolio.
If that particular business venture faces difficulties or any legal situations, only these assets will be directly affected, and not the full domain portfolio. Keep in mind that corporate formation laws differ from state to state, and from country to country. This is a general suggestion and not intended to be legal advice; always consult with an attorney in order to review your options.
In a nutshell: Organize your domains using a domain registrar that provides dependable tools for their administrative and sales management. Uniregistry and its Uni Market are a great choice.
