Welcome to the Q&A Forum

It sounds like your best bet is going to be digging up some analytics from your old site, finding common URL patterns, and redirecting them more thoroughly via rewrite rules.  A clever use of sorting in a spreadsheet can make this task go by much quicker, and if you have some key pages on the new site where you feel entire clusters of old pages can redirect that will help too as you're not redirecting one to one.  It would also help to tag the new site's applicable pages with rel=canonical. Lastly, you can apply a nocache tag to the pages on your old site, althugh they should be flushing out fairly soon. Those are the general recs.  There is a certain amount of time involved in the process, and it's not a strict number of days/hours/minutes.

Oh, for your 404 page (http://www.structural.net/;flkajhsdlfg) I'd recommend making it a lot more functional, especially since you're expecting a lot of 404 traffic in this current process.  Check out Apple's for an example (http://www.apple.com/lkjsfdawe) and this blog post for more ideas: http://www.seomoz.org/blog/personalizing-your-404-error-pages (an oldie, but goodie.)

Your domain strength is pretty high, so on your home page and top pages, those navigational links are going to be fine, but you could nofollow the bulk of them on the individual blog pages.

You already have the tweet and facebook like buttons that are getting use, but you might be able to add some easy to copy & paste code, similar to a badge, to try and boost inbound links (http://www.seomoz.org/dp/badges). Also, since you have so much content you could try getting a Polyvore-like feature added to your site that helps people make a collage from the different wedding details they like. (http://www.polyvore.com/).

I didn't dig too deeply so these are just off-the-cuff examples, but hopefully enough to spark some ideas for you.

Hi Tait.  I went through one of the blog posts with 20+ comments and saw that most of the links via user names are pretty wedding relevant--wedding photographers, profiles back to your own site, some broken links--plus they're already nofollowed already. It'd be a good idea to apply nofollow to the individual comment links as well below the user name.

If you have the SEOmoz toolbar you can turn on "Show Nofollows" here and see all the different links the 'moz is disregarding.  All the "Browse Category" links at left are nofollowed, the section tags, and the function links (Add Image or Video URLs...) I think you could take a similar tack with your blog and apply any incoming link juice to a few select links that are the focus of that blog post.  That way you're leaving the option open for people to be social via your blog and provide links for people to click, but the technical focus is around your target keywords.

To get more insight on where you could apply nofollows, just leave the "Show Nofollows" highlighter on in the tool bar and surf the web for a bit: competitors, blogs that would likely be in a competitive niche, etc.  You should be able to get a pretty good idea fairly quickly from that exercise.

Last, coming up with hooks for people to link back in to individual blog posts would be handy as any juice coming in would then be redistributed to your most targeted links.

Thanks!  When I hit 1000 I get a t-shirt!!  w00t!!!

It's not really a duplicate content issue, mostly a reporting issue in GA due to some tracking features people choose to implement.  There's a discussion here that tells you how to filter the issue in your reports: http://www.google.com/support/forum/p/Google+Analytics/thread?tid=65a45d4ad4f6871a&hl=en

Your sitemap should only contain current pages you want indexed on Site A, not the pages that you're redirecting to Site B.  It sounds like you have the right steps in place and that you will see your old links get removed over time.

For external links a straight division of of PR by links per page isn't the best correlation to Google's ranking and PR system. Things like link location on page, number of links to the same site, anchor links, link text, nearby text, and more all play a part in calculating how much link juice to pass.  The short answer, they don't exactly say.  The long answer can be found on the pages referenced below, but you still won't get an exact number.  The take away is that SEOmoz is constantly working to correlate their Linkscape produced data and rankings to Google's data and rankings.

If you want to go with more of a shopping cart sort of feel you could emphasize products carried within the brand and not really break away from general site navigation like:

http://www.bhphotovideo.com/c/buy/Shop-by-Brand-Roxio/ci/4/N/4294255798/phd/4291243286

Tiger direct uses a brand splash image, common product categories, and then products as seen here:

http://www.tigerdirect.com/applications/campaigns/campaigntemplate.asp?CampaignID=517

Walmart's brand shopping page is very splash heavy:

http://see.walmart.com/lego/

Dunno if I'm moving far afield of what you want to do with your site in general, but that should give you a few ideas to throw around.  I came up with the BH Photo example from memory and the other two via a "Shop by brand" search in Google.

It also would be nice to see a categorization feature by answer.  For example, I recently answered a question regarding 301 redirection and www vs non-www (http://www.seomoz.org/q/hostname-report-in-google-analytics) where the bulk of my answer was pulled from the SEOmoz "learn-seo" section.  That quoted answer could suffice for multiple questions so if someone has a nuanced situation they could scan through a block of questions that all have one answer and likely find what they need, sort of like a FAQ with links to all the questions that fall under that one answer.  Or perhaps a wiki format with links to all the questions that it answers.

My pleasure!  If you decide to go through this exercise send me a PM as it'd be neat to see what kind of results you come up with. Also, now that you have a few other search terms to consider (Mobile OS, Mobile browser, etc.) you might be able to find an article or report that speaks more directly to your search.

It's in the code so your developer would have to do it, from Google's Guide:

Can the link be relative or absolute?

The rel="canonical" attribute can be used with relative or absolute links, but we recommend using absolute links to minimize potential confusion or difficulties. If your document specifies a base link, any relative links will be relative to that base link.

http://www.google.com/support/webmasters/bin/answer.py?answer=139394

Trying making the absolute URL, i.e. "http://www.mysite.com/category/9-Irons" as your href instead of "/category/9-Irons" in the rel="canonical" link tag.

Google pulls reviews from across the web, not just Google accounts.

It sounds like if you're dealing with subtle tweaks and small details you'll need to get some insight into your specific situation, i.e. add your url and search terms to the discussion, or hire someone to hep with an audit.

To answer your question about subtle difference, yes, I've seen something as simple as being more centrally located within a specific area code give a better ranking in map results.  This was a while ago though, and I think it's changed some, but it is an example of subtle difference.  Of course this might not help your situation whatsoever.

Paulo, you'll have to test the speed of your site yourself, but you can do so at a place like: http://www.uptrends.com/aspx/free-website-server-network-monitoring-tool.aspx

It will display results from other countries and cities from around the world and help you decide whether or not you need a cdn.

Sean, the percentages are the Statistic divided by Country/Region. So if you select Mobile OS and Worldwide the 31.56% percentage for April 2011 on SymbianOS means 31.56% of the World's Mobile OS uses SymibainOS.  If you switch Country/Region to the United States the percentage will indicate that area's usage for that Statistic. Remember though, it's only measuring Mobile OS in this instance so it's not a percentage total of all web surfing traffic, just mobile web surfers.

You'd have to reverse engineer this data and plug in some statistics form another location on specific device usage or purchases in order to get a guestimate on the number of iPhone users, by device, within your countries of interest.

Hi Andre.  Here are a few problems you might run into:

1. Websites you don't own may outrank your money site  -- Even though they're your accounts on other sites they are owned by their respective companies.
2. Duplicate content penalties could delist much of your work.
3. General dilution of your money site content.

A better practice would be to do a lead that has a portion of the content and then a "Read more..." or applicable anchor text link that points to your money site.

Hi James.  Lets say you have 15 pages that are the canonical pages and the 35 pages that are variations (alphabetically sorted, price sorted, whatnot). If those non-canonical 35 pages are being graded they're not going to have a rel=canonical that lines up because they're not the canonical page. The on page report card is only looking to match the URL you entered into the SEOmoz system and the tag that you have on your page. Is that what's happening in your situation?

I doubt it, but just in case you missed it, the explanation from On Page Report Card: If the canonical tag is pointing to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. Make sure you're targeting the right page (if this isn't it, you can reset the target above) and then change the canonical tag to reference that URL.

Hi Prunarevic.  Can you clarify your question?  I'm a bit confused about what you're asking. Typical parasite hosting is accomplished by hacking into a website or finding an openly editable portion of a website and adding content that redirects to your target page.  It's not advisable, and if you break laws while hacking into someone's website it could be far more trouble than it'd ever be worth.

http://www.davidmihm.com/local-search-ranking-factors.shtml This is an excellent break down of the factors that go in to local search.  David Mihm is also on the SEOmoz website so if you need an expert in the field you can contact him.

As you can see from the article there are at least 58 positive indicators and 11 negative indicators that all influence your localized ranks, being a combination of localized content and regular ranking factors.  Hopefully by scanning through this article you'll be given several ideas of where you can improve your results.
