Will Google re-index the page if content is changed/improved?

Hello,
i have a little question, it seems most of my posts which are 3 years old or even more, all have almost same type of 2-3 lines of text at post starting and then images roundups etc. 
which recently stopped getting any traffic from google. Probably becuase of lack in text etc. 
So if i now edit those old pages, will they be reindexed in google with this new content/data? 
thanks in advance.
cheers

Instead of changing the text, I will recommend removing the whole content, edit it all and then post it again .

Hello, Thanks for the reply.

so that would be doing as you stated on the same URL right ?

Yes Ayaz, you have to edit out the content and Title ( include targeted keywords ). Don't change the URL as it might have some incoming links.
