Welcome to the Q&A Forum

The Spiders cant crawl the app ( assuming its a native app ) in which case I dont think there will be any "direct" SEO benefits, but you might get new followers for you brand who might  indirectly help in SEO

but if its a web app and if search spiders can index the content then it will have some direct SEO weight to it.

NOTE : this is just my thought ( would be interesting to see if anyone thinks otherwise )

Hope that help

I was wondering if you have a like button on the blog and people use it to like a post , is it possible to find out who all have liked the post ? ( there is a counter to show the number of people who have liked the post, but could not figure out who have actually clicked the like button )

thanks

thanks

Is there any tools available that allows users to track ranking of a keyword in SERP over time ?

I know the question can be a bit confusing so here is an example that I hope makes it a bit easier to understand

EXAMPLE :

I am doing keyword research for say "iphones games" and I find out the current sites that rank for the term but If I want to see who ranked for the term 6 months ago or 1 year ago, is it possible ?

Also can I get data of the SERP ranking history for "example.com"  for the term "iphones games" ? eg : in

jan 2011 rank 10

feb 2011 rank 7

...

sep 2011 rank 5
