Problem Solving With Panda Update

Hi guys I have a problem with my 2 sites...

My sites have as a niche: product and ebook reviews
age sites 2 / 10 years
all pages on my 2 sites are indexed on google (approximately 250 pages per site) but not rank well in the SERP
I dont have duplicate content on my site

can be a problem for the new google panda update?

advise me to work on the authority of my sites (site*com) or individual pages?

Copy a text from one of the pages and search for it in google. If your site appear, that means those pages are capable of appearing in google results. If not, that means those pages, though indexed, are not qualified for appearing in google results.

I did as you told me a few pages appear on the first page others not appear...

how do I qualify to appear on Google search pages?

What's wrong?

Thanks

That means the pages not appearing do not qualify yet to appear in google results even though they are already indexed.

The solution is to run some backlinks for those pages not yet in google results. That increases the authority of those pages and may be considered for inclusion by google

How many words in your content? Is your content useful? What is the bounce rate on your pages? Are users spending time reading your website content?
