Assuming your website is important to your business, then it makes good sense to regularly monitor it and make sure that it’s on track. The first thing to ensure is that your website is actually ‘online’ 100% of the time.
For example, let’s say your website generates income of £10,000 per month from leads or sales. So, assuming that people are looking at it during a normal working day, that’s 9 am to 5 pm, 5 days a week, four and a half weeks in a month.
That’s 8 hours x 5 days x 4.5 weeks per month = 180 hours per month to generate £10,000 pounds income. Therefore, your site generates roughly £56 per hour. Which means that your site needs to be up 100% of the time!
Other things to monitor are missing pages, dead links, incomplete images etc. Anything down or missing ultimately costs you money in some way, even if it just negatively impacts your Google page rank.
