EZ Website Monitoring is a new web service which is currently in beta and provides uptime monitoring as well as SEO monitoring. It includes features like Uptime Monitoring, Response Time Monitoring, Weekly Error Checking, Keyword Ranking Reports, Website Popularity Monitoring, and Historical Graphs. With this service you can monitor your website and also compare keywords ranking for your competition websites (maximum 4 websites).
Apart from monitoring website uptime, you can add your competitor websites and then check the keywords ranking and also in bound links, Alexa rank and other ranks.
EZ Website Monitoring claims that it does not just rely on ping method to check whether the site is up or down. It actually checks the load time, response time and also ping method so that it gives better idea whether site is up or not.
Uptime and response time is checked every 5 minutes. Error checking, keyword rankings, and popularity are checked once per week. Your report will show when the last check was done and when the next will occur. You will receive your report in email each week.
Currently the service is in beta and free to use for one month. Once it comes out of beta, there will be a fixed charge per domain.
Thanks for the good review Nirmal. It is good to note that if someone signs up as a beta tester now, and are approved, they get 6 months of service free. This is a thanks to all those that help us improve the service.
I would like to also recommend howsthe.com for website monitoring.
