I have played a fair amount the last week with GoValue from GoDaddy vs Estibot. I will probably write up a more full analysis somewhere if I get around with it, but thought these perceptions might be helpful.
- I agree with those who say that no algorithm based evaluation should be your only source of value information!
- Overall, I think GoValue is better than Estibot (I know many will disagree with that). It seems to me that Estibot is inappropriately extreme - it sets many to $0, but others way more than obviously worth.
- It is clear that Estibot mainly emphasizes search popularity, while GoValue primarily previous sales in closely similar domain names. Their huge database helps do this fairly well, and in general I find their comparators to be meaningful (Estibot less so).
- I find that GoValue tends to over value most domains, so while it is a good starting point, I doubt that you can get what it says (the exception is really high value domains, that may well be undervalued). For example they show almost any meaningful (or even non meaningful!) .com as about $1000 and clearly lots don't sell for that as Namebio reminds us every day!
- GoValue also overvalue domains where the name is good, but within new gTLDs GoValue seems to largely ignores the extension. If one extension, like com or net, sold for more than $25k they will make the other extensions, even when not meaningful, as moderately valuable (many hundreds to thousands of dollars). The user needs to evaluate which of these extensions make sense!
- Both have biases with respect to extensions. For example Estibot seem much kinder to .top than GoValue do, but some of the newer gTLDs Estibot make even great appropriate words $0. Almost every top I tried in Estibot I feel is way over valued. For example, I own kindness.top, which I like as a name, but I don't think I will get near the $3400 that Estibot list it at.
- To some degree both, but especially Estibot, seems clueless with respect to new developments in science and technology. For example CRISPR was the science breakthrough of the year more than two years ago, has huge search volume and lots being written, but enter it in Estibot and it doesn't even interpret the word right - it thinks it is crisp and r as a separate keyword. GoValue does better, making most of the new extensions from $600 to $900 recognizing that CRISPR.com sold for more than $25000. This is just one example, but Estibot is in my opinion almost worthless for new science and tech.
Anyway, I may make a more formal posting with quantitative data, but thought this might be useful. If both list a domain name as almost worthless (GoValue have the lowest category listed as <$100), or if both are consistent in a high value, I would have more confidence.
Best of luck valuing, and especially selling, everyone!
