If you’re looking for ways to increase your inbound marketing’s ROI, keeping a closer eye on your analytics—checking them at least three times a week—may be a good place to start.

That’s one of the key takeaways from HubSpot’s 2015 State of Inbound Marketing report, which more than in years past examines the factors that separate inbound marketing leaders from those who lag behind.

Just how big a difference is there between those who watch their analytics religiously and those who don’t? According to HubSpot, marketers who check analytics three or more times a week are more than 20 percent more likely to achieve a higher ROI than they did the year before.

In an area that sees results in real-time, it’s hardly surprising that those who closely monitor their marketing campaigns are rewarded. Monitoring alone isn’t enough, of course, but constantly evaluating the performance of campaigns better prepares marketers to both identify what works best and adapt what doesn’t work as well.
