EstiBot is the world's most trusted domain appraisal service. It is used by registrars, financial institutions, domain brokers and individual domain investors. The service relies on a statistically derived model to calculate the value of a domain name based on over one hundred internal and external domain attributes. The model is updated continuously to reflect the latest market trends. Internal attributes include domain length, extension, word count, pronunciation and other characteristics directly linked to a specific domain. External attributes refer to third party data such as a domain's search popularity, type-in rank, age and much more These attributes are then compared to those of previously sold domain names and the valuation is based on that comparison. The service was established in 2007 and now provides over 2 million valuations daily.
