Hi, I have a few blogs and when I serach in google almost all pages are omited by google.after do a research in google the cause is due a duplicate contenet and very similar title.
Anybody knows a tips for get indexed all the pages?

P.D. I use blogger so i can't change robots.txt or something like that.

Simple - use unique content and get some links - that's all.

Yes unique content it's true but in the other hand is very difficult dua my niche to have unique content.
So I put this thread in blackhat forum no in withehat ,and i want blackhat tips.

I have 1000 backlinks and is pr4 and still 30 of 130 pages indexed

First, remove your duplicate content from other sites you own, or blogs you use. Then contact them and explain that you had contacted those sites and asked them to remove your content.

Just because the title page is the same doesn't set off alarms within Google, and while no one is sure at what point something is considered duplicate in the eyes of google.

Typically if you want to use duplicate content on a blog discussing your information, I wrap quote tags around it in sections or paragraphs to distinguish it, so far, no problems.

Unique doesnt mean original, it means not copied word for word with exact formatting from somewhere else.

ok thanks for the replies, I'm not sure but I think the problem is not the duplicate content (the content are videos and a little description), is the the titles of the post that are all very similar so maybe google decide to omitted.
So i think the tip from Dilomat ( wrap quote tags around it in sections or paragraphs to distinguish it ) maybe works but i don't understand exactly how to apply
