I did listen, but I just can't wrap my head around that. Isn't it all about contents now, that's what everyone is saying. Unless, as the other poster said, it's about corporate interests, in which case redoing content won't be worth it. Or is it perhaps a combination?
Therein lies the problem more then likely. Based on what you've said it seems like your writing content for the search engines instead of your users. I'd look at ways to try and condense some of your content by combining different articles and perhaps even improving on them to feature more comprehensive articles that are more likely to get shared, tweeted, etc.
In regards to those who posted that changing the content won't help: I don't know about penguin, but since the begining of my days in SEO a good content refresh can make you rank higher. And there's no doubt about actual visitors, they would take much more seriously and you will seem more trustworthy with that content refresh. And those are two attributes that every serious bussiness wants to have associated to their brand.
Actually content freshness is overrated. What is more important is providing value, getting repeat visitors and people to share your content, etc.
Sure, I'm not saying to refresh content for no reason. I am saying my content is not very valuable to users and not worth sharing, in its present form.
Sad to hear this. best of luck for your success. Try to follow Google guideline's in future optimization .
Update: OP here. I am making progress and working on re-writing every page of my site. It's going to take awhile. Thus: If you are a content writer who can work in Wordpress and you have a bulk rate available, PM me with your offer and we can discuss! Thank you in advance!
