How Rel=Prev & Rel=Next work for me?

[CommercePundit]

I have implemented Rel=Prev & Rel=Next tag on my website. I would like to give example URL to know more about it.

http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=5

Right now, I have blocked paginated pages by Robots.txt by following query.

Disallow: /*?p=

I have removed disallow syntax from Robots.txt for paginated pages. But, I have confusion with duplicate page title. If you will check all 3 pages so you will find out duplicate page title across all pages.

I know that, duplicate page title is harmful for SEO.

Will Google crawl + index all paginated pages?

If yes so which page will get maximum benefits in organic ranking?

Is there any specific way which may help me to solve this issue?

i could not find any rel=next or prev in those pages, there was a rel canonical.

If you do a rel canonuical then you need to have the content on the canonical page. You can not have a page with ABC the canonical it to a page with XYZ.

If you use rel next and prev. the fiorst page will have rel=next the last will have rel=prev, all pages in between will have both. Google will give credit to the first page with only rel=next, all links pointing to any of the pages will pass link juice to that first page.
