Too often when working with a website you get comfortable loading and see the site working with your own eyes, but what does your website look like to others? Recently started working with a new client and the first thing I did was to add his sites to the Site Monitoring tool Pingdom. I like to keep an eye on how their websites perform, especially after I make any major changes to them. Response time is a killer to SEO.
After it ran for half a day I took a peek and discovered something strange, every 2 hours the website was unreachable for exactly 10 minutes. Bringing this up to the client they scratched their head a bit and responded “that’s odd… lemme look at my cron jobs”
After disabling a suspect cronjob and magically the site started running smoothly again as you can see in the chart above. Now to see if this helps improve his SEO and visitor conversion rate.
What Are Cron Jobs?
Cron jobs are scripts which run at predetermined times defined in a Crontab. This is a feature found on all Unix and Linux based web hostings.
