1. History of the Website
Look at the history if you want to buy a website, the longer it has been in existence the better because the website is already established. If you find websites that have existed for a few months and are getting sold then it would be better to start your own from scratch which is even cheaper.
2. Revenue Trends
The main reason you want to buy buying a website is because you need returns from your investment and so you need to pay attention to revenue trends of your soon to be business. How is the site’s revenue, has it been in constant decline? Does it have potential; is there something you can add to have it increase its revenue that is not listed there already? Has the site’s revenue increased just a few days or months before it went up for sale? This may be artificially inflated so as to sell high. This is a factor to consider when you buy a website.
3. Traffic Quality
This is the most important factor, because the more traffic the website gets, the probability of making money is high. For example, if there are ads like Google Adsense, you will earn because Google pays for impression of the ads (viewers of ads) and also chances are high that from the many visitors on your website some may click the ads and you will get paid for that.
4. Do you have the skills to maintain the website?
Many websites like blogs and content sites require to be consistently be updated with fresh content and if not, the traffic would rapidly go down.
5. Time and Money
Do you have time for your new website? A website may be earning $500 per month and you may see this as the best deal ever, but you need to assess the time needed to maintain the site at that level. Is $500 per month a good deal? For example if you need to spend eight hours daily, you will be hiring yourself at an estimated salary of $2 an hour. This may be too disappointing, so before you buy a website know the effort behind the success.
