Grep website links for a word

I want to search through all the links of a website for keywords and return the url

For example if I do

commands http://ift.tt/1orKfAV | grep 'art lessons at age five'

I would get

http://ift.tt/2ilsd4C

As a result

Or If I do

commands http://ift.tt/1orKfAV | grep 'Welcome to your place to buy Small Diary comic books!'

I would get

http://ift.tt/2jkYQxT
