I have started dropping on my rankings - due to lack of time after having a baby. I'm still managing to blog but I'm wondering if I update the content on my pages will that help?

All my Meta tags and page descriptions were updated over a year ago - do I need to update these too?

We were ranking in the top spots for a good few years, but we're slowly falling Please give me any advice to keep us from falling even further.

I have claimed all my listings, and try to add new links once a month. I share my blog to all social sites and work hard to get Google reviews, we have 53 which is higher than any of our competitors.

Any other ideas? Have I missed something that Google is looking for nowadays? Many thanks
