Is there any real benefit to Google Page Rank anymore?
Though PageRank isn’t as important as it once was, one benefit of
having a PR of 5 and above is that Google does seems to crawl those
sites on a more frequent basis.
How big is your site getting to be?
If you have more than 200 pages on your site, consider getting an
onsite search engine. Not only will you be making it easy for your
visitors to find what they’re looking for, but the stats you’ll get
with the onsite search engine will be extremely beneficial to you.
