Online tool for crawling a website and retriving all meta information for every page

Question

Does anyone know of a free online tool that can crawl any given website and return just the Meta Keywords and Meta Description information?

Answer 1

Assuming you have access to Linux/Unix:

mkdir temp
cd temp
wget -r SITE_ADDRESS

Then, for keywords:

egrep -r -h 'meta[^>]+name="keywords' * | sed 's/^.*content="\([^"]*\)".*$/\1/g'

and for descriptions:

egrep -r -h 'meta[^>]+name="description' * | sed 's/^.*content="\([^"]*\)".*$/\1/g'

If you want all the unique keywords, try:

egrep -r -h 'meta[^>]+name="keywords' * | sed 's/^.*content="\([^"]*\)".*$/\1/g' | sed 's/\s*,\s*/\n/g' | sort | uniq

I'm sure there's a one-liner or program out there that does this exact thing, and there are definitely easier answers.
