Hi, I'm hopng someone can help. 

I feel I'm getting conflicting infomration and I want to do my best to learn as much as I can regarding SEO and to try and update my site as best as I possibly can. 

With regards, meta keywords are they important? I've read articles that say they are outdated but then I have people telling me my meta description is very important. Are these the same? And if so am I best putting in keywords with a comma e.g. onlinesubscription, personalized service, ......

Or do I place in a sentence? Or do I leave blank which it currently is at the moment. 

My page titles apparantly are causing problems with my SEO but I'm not sure as to how to correct this as I thought I'd everything filled in right. 

Thanks in advance for any SEO advice as I must say with so much infomration I've received and read I'm confused as what's best to do and being a Weebly site, I thought it was best to ask here to hopefully resolve my issues.
