Our first disagreement MJ
- but - the toolbar pagerank of a site linking to you does not make one iota of difference -you can have a zero rated site 'with authority' ie a dot gov - that will trounce a site with a PR9.
I can understand why people think it does - but we did a real in depth look at Google's own links to its own home page - the
PR went up and down like a yoyo - it's own Matt Cutts blogs did well - and some of those posts were zero rated. It's the page that matters and relativity to topic. Not the sites
PR - but the pages natural internal rating.
Self edit - prime example
Official Google Blog: Introducing Google Earth Outreach zero toolbar pagerank
Now assuming that you have links coming in from a Google Alert -well we have touched on that previously - Google never ever ever looks at the toolbar
pr - it looks for one thing and one thing only - relevance. Think about this just for a second. Where do bots crawl? Sites - Where is toolbar Pagerank? - on a Browser -it's not on the site!
