Welcome to the Q&A Forum

Vary your anchor text, link out from only from only a few pages (their strongest pages, preferably) and make sure each of those outbound links point different pages on your site.

I can see how dupe images it might be an issue if you rely on image search for traffic but likely not in your case.  On the other hand, 400 pages with the exact same image...? That is a lot.  It seems that you might help yourself if you alter each image with a little copy specific to the page you've put it on and tailor the alt tags so that they're aligned with the image and the geo data for it's specific page.

Often you're better off ,putting your efforts into a single domain and getting that to rank, rather than splitting your efforts between all those other domains--I mean, what  are you going to do with those new sites that is going to get them to rank that you couldn't do with your original domain?  If they're exact match domains, I wouldn't count on their effectiveness for the long term--or even for the short term.

Use your OSE report to find pages that are being linked to from external sources and be sure to redirect all of those.   Use your analytics report to find pages that are bring in search traffic and be sure to redirect those. The rest are neither being linked to nor bringing you any traffic so their priority is on the low end, anyway.

If you already have the 4 sites running on different domains, each has different content, and you linking sparingly and appropriately between the domains, I'd call it a toss up as to whether it's better to keep them separate or bring them together.  Have you looked into buddypress for managing the separate domains within a single CMS?  I think it can handle that.

Hi goodcat, you'll see from the FAQs on this page http://www.seomoz.org/help/crawl-diagnostics that the report data is from seomoz's crawl.  Your question was asked and some answeres provided not too long ago over here: http://www.seomoz.org/q/is-it-possible-to-get-a-list-of-pages-indexed-in-google.

Do you already have a main site that is ranking for all the main keywords and you're just about to roll out these five new ones or are these five new sites your first ones and your business plan revolves around those five?

A search engine considers a subdomain to be a different entity from the root domain and links to and from are considered external.  Don't be counting on those links from the subdomain to be doing much for the root domain, though, unless your root domain is a strong entity unto itself.  A few links from separate pages may be helpful but engines won't be oblivious to the fact that  their coming from the same IP address as the root domiain (as most subdomains are).

Hey Morgan, I've seen this often with professional sites of all sorts. The vendor is selling a content service but the buyer is either not aware that the same content is being sold to all their clients, or not aware that it makes a difference.  Often, the buyer is on the hook for the service for a year or so.

Here's the thing: Competing in the search engines is about differentiating your website and getting people to engage with your content--and it's hard to do either of those things with content that's common to hundreds or thousands of other sites.  In answer to your question, the duplication doesn't necessarily make you site irrelevant, it just doesn't give search engines a reason to rank it higher than the next dentist.

What that content does do is provide your local visitors with a feeling that your practice is up to date with news and technology and that can be an advantage over a site that lacks any updated content--you'll just have to drum up those visitors from somewhere other that organic search.

One of those other places is local search.  With or without dupe content, you can still focus on making your local results stronger and it can be argued that that's better than showing up in the organic results for many dentists.

James' advise was solid.  Put the blog on your main site and focus your limited resources on producing quality content and on outreach to promote that content.  You've got to get good links to at least one of the sites, and with that being as hard as it is, you might as get them to your main site--which means the content needs to be there.  Once site A is overflowing with content people are clamoring to link to, then you can think about doing something with site B.

Think of the gazillion Wordpress sites out there--they're all the same architecture and they can rank.  Your tactic used to be more prevalent, back when linking between sites (you won't be doing that, will you?) with thin content (they won't have that, will they?) helped lift all of them in the rankings.

While there are plenty of examples of multiple sites owned by the same company showing up in  the same page-one search results, there are as many, or more, examples of them all showing up at the bottom of the results.  It seems to me that if you're asking the question you're asking --at this point in the project, you may not be well enough informed to keep yourself out of the later group. I'd kindly recommend doing some additional homework before you launch.

See if he'll let you do a 2 month  test with a different home page and let him see the difference in the traffic/business and then let him make a more informed decision.

On  the other hand, the page that all your "home" navigation links go to should be a page like the one you wish your home page would be--a page with a bit more static content than the /начало/ page and one that other parties might link to instead of the domain's (current) default page. Develop your external links to that page.

In the market you're working in, you better have real, link-worthy, thought leadership-type blog posts regardless of what's on your homepage because it's likely that the majority of your search traffic will land on your blog posts--at least until you build awareness and strength for your brand. Don't blame the lack of traffic on the boss' decision on the home page if you haven't pushed really hard for top quality content. If you've done that and he/she hasn't complied, blame the lack of traffic on their business sense, not necessarily on the web site.

They're not the same.

Redirect the pages that have links going to them to their counterparts with the new URLs.  Look at your stats and see which pages are bringing in search traffic and redirect those,too. Google will sort the rest out.

You're going to end up with a siht-load of bad back links and a poor back link profile that will leave the squidoo page with little  to no value and which could reflect poorly on your primary site.

The fact that you're getting dramatically different views on the issue leaves open the possibility that there is no steadfast rule to go by here. If that's the case, your SEO experience should be telling you to tread lightly.

A few years back, Bill Slawski wrote a post about what search engines think about reciprocal links. Some months later, Eric Ward a post expounding on "Why Reciprocal Links Will Always be Viable".  Both are still relevant and good reads.

If you're just 3 months away from the move, it's time to revise (vs. create anew ) the landing page(s) that will reflect your new location and get those online asap, so your organic results can start percolating.

Adding a lot of SKUs to your site in a relatively short amount of time by borrowing content from another site sounds more like a bad sales pitch than a good "opportunity".  If you don't want to put in jeopardy a significant chunk of your business, then simply drip the new sku's in as you get new content for them. The thin content's not likely to win you any new search traffic, so unless their addition is going to quickly increase sales from your existing traffic sources and quantities in dramatic fashion, why go down that road?

Don't mention it : )

You may also want to look at anchor text for your links pointing from instabill.com to blog.instabill.com.  It would probably be better to use "Instabill Blog" vs. just "blog" and even better might be simply "Instabill", if you could get away with it.

Give this a read before deciding: The exact match domain playbook.

I've seen people recreate their primary landing pages at new URLs, link to them from a custom sidebar menu, and then rel=canonical the original landing pages, linked to from their primary navigation, to those new URLs.  I wouldn't do it, though.
