Visit sites such as Iwebtool and Quickpagerank to determine your Alexa ranking, that is, how popular your website is compared to others on the Internet. These sites may also provide your position on various search engines as well as inform you of any existing backlinks (links from other sites to your own) with them. Record these in a Microsoft Word document.
Install Google Analytics or make use of Sitemeter's visitor measuring tool to accurately assess your site’s daily and monthly visits. Divide Google Analytics' monthly figure by 30 to determine visitors per day. Avoid using daily unique visitor data as they’re sometimes confusing or erroneous, according to digital marketing evangelist Avinash Kaushik, founder of Market Motive.
Retrieve site records to establish exactly how old your site is. Ensure the date obtained is accurate to the first day of publishing. Estimate to the nearest month if you find your site’s age slightly above or below a certain age.
Check your site’s financial records to determine monthly and annual income as well as the appropriate monthly income ratios: what portions of your revenue come from sales, donations, ads, etc. Be sure to use net after tax cash flows to get a more accurate picture of your site’s worth. Document these as well.
Spot check any differentiating characteristics of your website such as registered patents, copyrights or trademarks associated with it. Arrange these in order from most to least valuable. Calculate their total value. Record these on your ongoing valuation sheet.
Input all of the above in one of the widely available online site evaluation tools. Good choices include sites such as Glurk and Sitevaluecheck, which, by factoring in more variants, give you a more accurate estimation of your site’s worth. Wait a few moments after inputting your data, then record your first estimate.
Visit other sites offering similar services. Fill in your site details as above. Record the estimates you obtain. Sum up all values derived and average them. This is your final estimate. For a more accurate figure, Glurk advises, you can approach one of several domain appraisal companies.
