Search engine optimization

[Guest]

Hello all!

My question today regarding search engine optimization is: I have noticed
some sites "source code" have the following:

meta name="robots" content="index, follow"
or
meta name="robots" content="all"

Was is the difference between these two and how does it affect the way my
website is indexed?

Also, I have noticed some site have the following:
meta name="revisit-after" content="15 days" (or "30 days")
What is the significants of this tag?

Thanks,

Henry Contreras

I can't answer the first part, but the thing about "revisit" I assume, tells the
search engine robots to re-visit your site and reindex it i.e. you may have added
new content and hence new keywords, or added new pages that you would want people
to find.

Don't use either. Robots naturally follow links unless you explicitly
tell them NOT to index something or follow a specific link(s). The only
time you need to use a roots metatag is if you DON'T want something
indexed.

Don't use this tag either. It is a "limiting tag" -- it won't bring the
spiders back any more quickly but, for spiders who pay any attention to
it, it may tell them to go away. Let them come according to (1) their
own schedules and (2) how frequently your site is updated.
