Welcome to the Q&A Forum

I updated my site to remove duplicate titles and also include the rel=
"next" etc tags. When can I expect to see these reflected in Google andSEOMoz? I also found out I should update my sitemap every month, when will Google pick up the new sitemap? Sorry if these are basic questions, new to the whole world of SEO. Thanks M

Is this something I should b concerned about? I get about 6 posts per page with unique titles - however the title per page is not unique. Is this important?

I'm new to SEO and have just signed up to SEOMOZ to see what I can learn. I got the report back on my site and it indicates various errors, one of them being Duplicate Page Title - I have a blog on my site and a lot of pages identified as with duplicates are like this: http://www.martinspencephotography.co.uk/blog?page=2 Is it important I rectify this? Do I need to rectify it?
