Those datacenters jgold454 listed show the search results I had before this "new and improved Google".
On the datcenters jgold454 listed, one of my phrases is #1 and #2, with #2 having the "more options from mysite.com" expansion + mark. That phrase is now #13 on the new Google.
I'm going to look through all of my outbound and inbound links to see if there's any commonality.
On the "nofollow" issue, I'd just like to point out that I only use nofollow on the banner ads that I have on my site for three advertisers. I'm sure I have some inbound links that are nofollow.
As far as images are concerned, I have product photos on a couple thousand pages, but each of those pages also has at least a couple of hundred words for descriptions and spec's.
Moving on to the duplicate or scraped content point, as I've said, I have photos, descriptions and specifications from manufacturers. Some of the text by necessity will be the same as the manufacturer (and thus other sites), but I've made as many changes as possible. One site that's devoted to one manufacturer has now moved up in rankings. The site doesn't just use the manufacturer's text and photos--it looks like a clone of the manufacturer's site, with the same graphics, videos, menus, etc.
On the point about old content, I've added hundreds of new pages of content recently. I added a new manufacturer, with hundreds of pages of that manufacturer's products. Good photos, re-written content. I was ranking about #12 to #15 for "Acme widgets". I'm now at #163 for that phrase.
I don't think it's about old sites, since many of the sites still on the first page have been around since the 90's.
One thing I do have is thousands of forum signature links. There's three industry-related forums that I've been a member of since 2000 or so, and I have several thousand pages of posts with links in my sig line. At least one or possibly two of those three forums are nofollow. Anyone else have a lot of sig line links?
What's left to examine?
