Search engine optimization

[Guest]

Hello all!

My question today regarding this issue is: I have noticed some sites have
the following on their sites "Source".

meta name= "robots" content="Index, follow"
meta name= "revisit-after" content="15 days" or (30 days)

What does this function accomplish as far as search engines go? and will it
really imporve your results ( rankings) Like for instance "robots" "index,
all" what is the difference between this and saying "robots" "index, follow"

I'm a bit confused about this. Can someone help?

Thanks,

Henry Contreras
