So Aaron Wall dropped a nice tidbit that comes right on time for me – I hope it helps you in your efforts as well when it comes to identifying large numbers of folks who are potential link partners: cache date.
In comments Wall clarified what he determines by the cache date:
* general health of a site you own
* general site of a health you are thinking of buying
* general health of a site you have the ability to publish content on
* trustworthiness of a link source
It is this last purpose that I’ll bring up with my buddy who’s going to scrape scrape scrape (and then scrub a little too I hope
me up a huge pile of urls and email addys so I can start going “door to door” more effectively for my clients.
Most SEMs don’t believe that Google actually uses PageRank. I think that if it’s all you have you should use it, but hey, it’s not all you have (and really there are tons of factors besides even cache date you should be thinking about when you conduct link building campaigns… I’m sure Fishkin has a post on this somewhere and I’ll poke around for it for you
.
Wall linked to, and so will I, a tool from Boykin called the Cool Cache SEO Tool!
And while you’re at it link builders, check out Making your content Del.icio.us by Mr. Patel.
And then quit thinking about marketing with me for a moment and meditate on the reason many Americans had the day off today… Martin Luther King, Jr.: “I Have a Dream” (20 minute video of his famous speech). ![[]](http://www.searchmarketingstandard.com/wp-content/themes/sms/images/entry-end.gif)



You covered a lot of ground there. From link building to formulas to MLK. We actually do pay attention to PR. No matter what, a high PR is generally a good sign and if the site is on topic, it is probably worth pursuing for a link.
I tried to test out Aaron Wall’s Idea and wrote it up in a blog piece http://www.sitevisibility.co.uk/2007/02/has-google-cache-killed-page-rank.html
Its true that the cache date is a very important SEO factor, especially when exchanging links with other sites but Page rank is also essential. Good article overall, thanks for writing
Hi!
Are there any formulas out there that can help to estimate how many link with what PR rank are needed in order to bring the site from let’s say position 20 in Google to top 5?
thanks
