Welcome to the Q&A Forum

By the product segments not being directly related, I would ask how indirect is the relation?  Are we talking Fresh Produce and Cars or Tablets and PC's?

I would highly suggest building a single site unless you have some regulatory factors that keep you from it.  Think of other eCommerce sites and the product diversity they have.  eBay, Wal-Mart etc.  There is a lot of variations.

You may want to put product information and blogs into separate folders for each product, so you build a clear set of data defining the products you sell.

What you ideally want to do is set up the mobile site as a standard site.  Then utilize javascript to call each page in an order defined by the users actions with dynamic loading.

This has two benefits:

1. SEO and SERP.  The pages will be indexed as they should.  If you have one huge page you are still limited to the 2 or 3 keywords as always.  When you see a good infinite scroll website it is not one page, it only looks this way due to JavaScript calling additional pages at triggers that have been set.

2. No JavaScript graceful fallback (or fallforward as it is actually the native state).  If you have one page, lazy loading with JavaScript and they do not support it then you have 2,000 pages worth of images loading at one time which is otherwise known as a bounce.

You will want to build out the site with no consideration to the infinite scrolling (except in design ie. tile-able backgrounds for a smooth non stop flow) then apply the script after you have a logical site structure using silo'ed categories.  Google bot, Google bot mobile and users who do not have JavaScript will all have a useable site and the SERPS will rank pages as they should.

Tip:  Keep any page wide bar or graphic styles in the header or the footer of the page.  You will normally only call the content or article portion of the page to the infinite scroll so you have a non-stop flow on the site.

Hope this helps

I know your not using WordPress but I am assuming you are using some sort of templated PHP script for a 2K product store.  This WP plugin is pretty easy to understand and what I first used to grab the concept.  Also, if wanting to go a more Pinterest route look into Masonry JavaScript.  http://www.infinite-scroll.com/

I spent a few moments looking at the site and source.  I am not sure yet why you have gone to PR0 for all of your blog pages.

A few things that I saw while checking things out (some of it is probably opinion over fact as I am not sure the overall effects)

Your robots.txt is setup to have all of your WP-Admin and WP-Includes indexed in Google.  I would set both of these folders to not be included.  (You may already have it done in metas etc. but I would put this in my robots.txt

Your robots.txt also needs to declare http://robt.info/sitemap.xml as your sitemap.  It is currently pointing to an attracta sitemap that points to another attracta sitemap and then declares your website to have 9 pages in total.  I am sure you have your sitemap submitted with Google but it is still  a much better practice to have the sitemap link in robots.txt point at your actual sitemap.

You may know something I do not but in your meta tag I do not think you need the /posts/ after your publisher google+ meta link.  This link does not actually appear on the site and used only by the search engine to identify the link between your other online works, Google+ and your site.

I saw these things and thought I would mention them.  I do not think they are the cause of your issues however.  Do you have a Google Analytics and Webmasters account setup?  Do they offer any insight as to why you went to PR0 and it seems like Google may not have very many links for your site.  This may just be the datacenter I was looking at though.

I will follow this post and try to be of more help.  To be honest I now, like you, want to know why.

I am not sure I understand the problem or the question.  Assuming others will be as foggy as I am the best advice I can give is to expand your question with more details as to your situation and question.

If the on page grader is an F for a keyword then it is reasonable to assume the link will not be very valuable for the keyword.  A better test would be to see where the page is currently ranked in the SERP for that keyword.  The onpage grader is a great tool but I do not believe it has adjustments made for over optimization penalties that are now in Google algorithms.

But the current value of a page to a keyword is always clear by simply finding it in the SE you are optimizing for.

To add an actionable response to the mix.....

I suggest making a list of authority sites within your niche or closely related.  Research what kind of sites they are linking to (if only gov sites etc. then scratch off the list).  If you find other sites similar to yourself that have links then make a resource not currently available and start a campaign that has merit as to why high authority sites SHOULD link to you.  (for the benefit of their users and their site)

"I want to make money" is not unique in any way and in my opinion if you are teetering on turning to spammy farm style marketing to build your site then you are probably a long ways from where you need to be.  When you are talking about yourself you will find few to listen but when you start talking about others and focusing on ways that you can be an asset to them you will find an audience truly interested in what you have to say.

For example:  Dedicate a small section of your site to filters specially for homes that were certified with Energy Star AirPlus at the time they were built.  Then go to http://epa.gov/iaplus01/join_now.html and sign up as an ally to the program.  If accepted (it is not tough by any means) then you get a DA 100 dofollow back link from the ultimate authority in your industry, the EPA.  Doesn't that sound like a better long term business building option than choosing strategies that will position yourself as the enemy to a $100 Billion Company that controls 70% of the worlds search volume?

Your client's would have to OK it but often when products are no longer available it is an internal issue and not a lack of manufacturing.  On my sites, if I chose to drop a line I will offer both alternatives if I have any but then also a link to where the exact product can be purchased (rel-nofollow of course).

It is more important to me that customers feel like clicking the link to my shop will never be a waste of time than it is to hope for the occasional conversion to another product.

Once a few click throughs mount up, I also find products I have the that the other shop does not and send a "Hi you may have noticed the X clicks I sent you for X product at URL.  I noticed you do not offer X but have content relevant to it.  If you think it would help us both out, I would welcome the partnership and be happy to keep sending business your way.  I think a link to X would work well "here", let me know your thoughts.

I sell a lot more to people who are looking for exactly what I have then I ever did tried to convincing them that what I have is what they are really looking for.

I have no idea what MOZ is planning to do but you have to love the SEO benefits of offering mobile friendly sites and video as well.

I have had the 1, 2 or 3 spot for SEO my town for nearly 3 months from a half hour of work with video and while we have double the amount of desktop traffic we are tracking 3 times as many of our sales or goals from mobile devices.

I just want to inject, we had a client worried that this was hurting their desktop results because they were scoring better on mobile but it is not an indicator of that at all.  Google bot Mobile is one index and Google bot is another.  The mobile simply has few competitors and is easier to rank in.  This is why you do not have to worry about duplicate content when you chunk out pages for mobile as long as you make your sitemaps correctly.

I didn't serve to answer your question at all but I loved seeing your post and had to comment.  

If you are wanting to continue to link to the old domain within the old domain but remove any hits from the new domain I would simply put a canonical tag in the old domain designating the new domain as the content source.  This way you can continue to use it and link to it within the old domain to allow a unified UX and give full SEO credit to the right spot.

For another view, OpenCart is great.  It has some wonderful features out of the box like coupon codes, gift certificates, an affiliate program, customer loyalty points and a lot more.  It is on MVC architecture so your theme, your code and your data are all fully separated.  This makes it nice if you want to add a mobile store then normally you have to either build one from scratch or use a program that manipulates the desktop site and make it work on mobile to some degree.  MVC allows you to simply use the same product pooling and build up a mobile site the same way the desktop site is.  But it is built to be mobile from the ground up.

I am sure many have this as well but if you adjust product much for $30 you can get an excel upload download module that allows you to build your product in excel which makes it uber simple to view a layout of your keywords and work with them to get the right flow through the cart.  You can even pull it and do a side by side with MOZ.com spreadsheets and fix your issues with ease then upload it and done.

It also has VQMOD which means that plugins can be added via XML at run time.  If you remove the xml file then the default files are rendered again instead.  So if a plugin breaks your cart, just delete and go.

The multi-store system is nice as well if you have use of it.  I spend about $400 on scripts with each OC install and end up with a eCommerce, mobile commerce and Facebook store that is fully integrated with oAuth2 and builds a newsletter list as well as a push to Facebook marketing list and control center in the admin.  Orders are emailed and print on payment receipt, abandoned cart reminders, GEOIP with 37 languages and 17 currencies that are fully automated and even rewrite parts of the code in the native language which helps with SEO.  Very CDN friendly and while there are a few quirks they are very easy to work around.

The MVC makes it fast to learn because you do not have all the code in one spot.  This makes it easy to follow and learn.  I have an OC install with a 5 pic 980x400 jQuery slider and over 2.5mb of other pictures alone on the front page with all the bells and whistles that loads in just under 1.5 seconds.

Security is also easy to achieve.  Of course nothing is secure out of the box but it does have SSL integration etc.  You can find a walk through to harden it and be done in about 5 or 6 hours your first time and 2 hours total once you know what to do.

I am not 100% as to your question.  I think you may feel like you are gaining value by this but unless you provide moving services then you are not.

Are you doing anything wrong by that, not necessarily.  Did the client pay you to make the tool?  Are these keywords relevant to the client?  You are keeping them from being indexed with their site where they may have value and instead putting them on your site where they do not have any value.  You are getting hits for traffic pulls but no SERP is going to see that as traffic for your content and if they do it will probably be seen as a bounce because the iframe is pulled and they are gone.

If you are doing it because you have faster hosting or simply for more domains and faster page loads I would suggest using something like jQuery get() to cross domain fetch it from a deep directory with no index directives from the feeder location so that it can be indexed within the site where it belongs.

The tactic is not wrong just check your thinking.  Think about the end user and think about being transparent.  You want to be up front both with Google and with the end consumer.  Nothing gains trust faster than truly having nothing to hide.

Fore sure.  The reason is that not all sitemap files are simply sitemap.xml it may be sitemap.gzip sitemap.zip or in my case, sitmap_index.gzip.  Also, some people may not be able to include their sitemap at root.

Including sitemap exacts in robots.txt gives a clear directive to each of the search engines exactly where to find your sitemap.  Google and Bing/Yahoo will have no issue finding it as you probably submitted it to them but crawlers like ask.com will usually look at your robots.txt and skip your site if no map is placed in it.

The simple answer is No, you should not use a plugin to build back-links.

There are some great WordPress Plugins out there that help you with tracking your back-links, I suggest the MozLinks one, it's great.  But it monitors your work, it doesn't do it for you.

Much like their brick and mortar your client needs to understand that business online is business, all the same.  You wouldn't trust a script written by a shady company to hire your employees or automate your accounting, you should not take such a route for building your site either.

Automated scripts are a clear violation of the Google Webmaster Guidelines (and the other search engines too) http://goo.gl/bdca8 you can read it on their site.

The other thing is, automation means no control.  You can end up linked to bad neighborhoods like porn and RX sites as well as get de-indexed and not show in the SERPs at all.

What to do?  Put your efforts on building a purpose  for your site.  Provide value in its vertical that is unique and useful.  Build links when you find others that have done the same and ONLY link to sites when you are willing to put your reputation on the line for them, as in a way that is what you are doing.

Want more visitors?  Answer one question.... why?

Why would someone want to visit your site?  Ask it everyday and answer it in a new way and you will have more traffic than your shared hosting plan will allow.

I have dealt with this quite a bit and I think first off it is important to mention that your sites are about your customers.

Do you think that a client or potential client could end up on one site but intending to find the other?  With Google, Yahoo and Bing out of the question, what would you do?

I spent my first 3 years trying to SEO for Google.  In the end, they did not purchase a single item from me.  My point is that even if they were to hit you on SEO (which I do not think is going to happen) I would choose the hit vs leaving a client stranded on the wrong site with no way to get to the content they are searching.

Google has cracked down on single purpose sites for a single business trying to dominate the SERP ie. one restaurant with the same content on 4 sites trying to get 40% of the first page SERP.  So if you have two location of Bob's Restaurant you should have one website for this.  However, if you own Bob's Restaurant and Lucy's Diner, you should have two.  They should be connected via links as they should connect to other local restaurants as well.

There is nothing wrong with linking to other sites you own, ++ if they have similar topics.

What to avoid?   Linking to them on every page.  Forget Google!  Where would you put the links so that it best helps your users?  Now remember Google, they want to see you put the links where it will best help your users.

I sell a lot more to people who are looking for exactly what I have then I ever did tried to convincing them that what I have is what they are really looking for.

There are several reasons that this happens.  The main being that Google simply does not index everything you have, especially if many of them are the same size, same meta, or they find patterns real similar to other sites.  The more social signals you have, the longer people stay on pages etc. will have an effect on what they index.

But the easy answer is that they are not all indexed because Google does not want to.  

In their words:

The number of indexed URLs is almost always significantly smaller than the number of crawled URLs, because it does not include URLs that have been identified as duplicates or non-canonical, or less useful, or that contain a meta noindex tag.

Also, there is a great resource on Google's indexing of sites found here

I am not sure what you are seeing or the conditions but I have noticed that sometimes when cdn's are used you will actually be sitting on the subdomain or another domain all together when you click on the page.

Some caches can make the same thing happen sometimes.

Make sure you are sitting on the actual page when it pulls up.

As far as the opensite not showing any links, if you copy n paste from the address bar and have any variation of the page, it will not read correct.

Make sure you have your actual desired url, is my advice as SEO juice will follow the canonical meta but the tools will not.

That is all I can think of anyways.

I do not know anything about Followerwonk as it has always just worked for me but my suggestion would be to:

1. completely log off and shut your browser down.  Restart it and clear all cache and cookies.  If using Internet Explorer you may also want to shut off the PC (Not hot restart but shut it down) and let it set some seconds and then restart it.  (be sure to clear the cookies before restart).  Also, if using Internet Explorer you may want to invest some time looking into a better browser.

2. No go?  Log into Twitter and remove Followerwonk from your approved apps list.  Log into Followerwonk making sure that you are logged into MOZ.com first and reconnect the two.

Again, I am not familiar with Followerwonds idiosyncrasies but I know that when my Twitter apps are having any type of issue with aligning oAuth2 accounts about 80% can be fixed with a reconnect.

Several factors are at hand.  I understand the obscurity but it also makes your question impossible to answer because a keyword like Nike or Coke is going to have a huge effect while a keyword like Chicago is going to have next to none.

The separate sites does in deed have some merit but I would look into that.  I know that Google is on the hunt for the same businesses that are trying to keep two sites in the organics acting like they are different but in fact are not.

No matter what I did, I would move fast because it will not be long until keywords being in the URL will have little to no effect at all, unless a branded keyword of course.

The other thing to consider is that sending clicks from 1 and 3 to an experience that is noticeably the same offering is only going to skyrocket your bounce rate, maybe on both sites and then send them to the bottom of the tank.

If you are to get your new site up to the top spot, you are going to have to build a completely unique and individually relevant experience for it to do you any good and I would make sure to not have them sharing any resources.

My personal advice, if you want to make the switch then do it Google's way.  I know many do not like that path but personally, I have enough challenges from day to day without positioning myself where a $200 billion company is dedicated to blocking my success.

For my business we provide services to a broad client base and people were getting confused on a single site.  At the end of the day, we build websites for people first and everything else is second on.  For UX it was necessary and we did what we had to do.  We fight to still make it very clear to the bots that we are one company and we have some overlapping content which now we can cross domain canonical.  The right way is to 301 your old site to your new once it is up in the rankings and pass your juice.  The other way is to make a few extra bucks and invest in them in tissues.  You will need them when you wake up to the "Site not found in the top 100" X 2.

To their blog for more?

One option you may consider so that at least you can have one page found from the gallery is to add a rel=conanical tag to their headers designating one of them as the page to index.

If you are willing to block all of the pages then your better option is to leave them as is.  Duplicate content on your site does not black flag you at Google or make non duplicate pages rank worse.

All it does is this:

Content page has an example Authority of 50.  If it is the sole page with that content then all 50 points go to that page.

However, if you have 5 pages with that content, then each of them shares the seo goodness and have 10 points each.

Now when the SERP is built your 50 points that would have maybe got a first page rank is only valued at 10 so it falls much further back.  Still higher than noindex tagging will get though.  

Hope that helps.
