Expired domains are especially attractive due to key SEO factors that are primarily associated with an existing backlink profile. If you are considering buying an expired domain, you can determine the quality of it by looking at the inbound links. When it comes to assessing the value of an expired domain relevant keywords contained in the second-level domain, a possible reference to products, brands, or services are all useful.
Once you decide to sell a domain name, it is important to find the best market to sell it. The best way to sell a domain name is to approach buyers secretly. If you know someone who deals with domain names, it is recommended to contact him without going through the middleman. Chances are that the seller will make more profit, as he will not have to pay the middleman.
That said, my recommended budget for beginners would be $500+. Using this budget you could buy a bunch of high-potential $10 domain names, expired/dropped domain names or a mix of both. It’s very important to invest only what you can afford to lose and treat this as a side hustle till you get the momentum going. As you gain experience, industry expertise and some sales under your belt, you can then consider slowly growing your business into a full-time gig.
