The common thought is search engines consider the sub domain as an entirely different website, but your sub domain may be your competition.  If you are selling yellow widgets on example.com and you are selling widgets on affiliate.widgets.com, you are competing against yourself.

Many of the errors and warning you are getting may be affecting just the affiliate.example.com.

If you site at affiliate.mysite.com, search engines probably recognize the content in the iframe as belonging to the Affiliate Company's website.

I believe you can do the diagnostics here for separate sub domains.  That may help your focus on your controllable content.

There is no link from that page to the 'tag' page - I checked.

If you deleted the tags, then you have probably fixed the issue.  Check when Webmaster Tools last crawled your site.  It was probably before you removed the tags, so the problem should be gone after the next crawl.

Do submit a sitemap in Google Webmaster Tools, it helps with the crawl.  There are free sitemap generators on the web.  I don't recommend using a WordPress Plugin for generating a sitemap because I like to use as few plugins as possible.

But with WordPress you need to use one of the plugins to rewrite titles and avoid duplicate content issues.

If you didn't alter the template files, then that is probably not an issue

OK, I learned something today.

I looked closely.  Linked in is using a temporary redirect, that apparently results in the same as a nofollow.

I keep a little text file with the easiest generic code for buttons to social links, that I can paste quite reqularly.

Many of them are javascript and ugly, but I refuse to link to add this, etc..

Fix them fast.  Look for commonalities in the errors.

Relative Links in Template Files Cause 404 Errors

You may notice a bad link in the header.php file.  If you fix that link, you will fix a bad link on every page.  If the link in the header is relative (e.g. href="/contact-us/") there will be broken links on pages on categories and tags, and more.  For example a the page http://www.example.com/category/goats/page-2/  is going to have a link to http://www.example.com/category/goats/page-2/contact-us/ because of the relative link in the header.php file.

In a template page, links should use the full domain, like below:

[Contact Us](<?php echo esc_url( home_url( '/' ) ); ?>/contact-us/)

Relative Links in Content Causes 404 Errors

Relative links between pages on your old site may have broken when you moved your content into word press.  If you have a link to your contact form in the text of your web pages, it will be broken.  Although you may need to do these individually, it is quick to locate.

Extra Pages?

Extra pages is puzzling. How did you merge the blogs?

A big bonus is YouTube will serve non-flash versions when embedded on an HTML 5 page, so the embedded video will show on page on an iPad.

Some are; some are not.

.edu is not necessarily better than some .com.  If the link is from a university's law school resources pages and links to your site on law books, this may be more valuable, than a student's page with a lot of links to and discussions about what beer is best for getting drunk the quickest.

The Google algorithm does consider the trust factor on domain names.  Because just anyone of the street can't get on GoDaddy and buy example.edu, it will automatically get a trust boost.

Some discussion of the different values of the .edu can be found at:  http://searchengineland.com/explaining-edu-link-value-with-examples-64012

That really depends on why the one site is ranking higher.  Is it's content better?  Google doesn't really care about how nice the site looks, but real  people do.

If you are just now launching a website for your company/organization, it is probably advisable to have only one or you will be competing against yourself - your competitors will reap the rewards.  Keep the domain that is performing better.

Do some searching about 301 redirects when you move to one site.

I would make a very small mobile site (even if it is a single page) because there is thought that Google is liking mobile sites - particularly of local searches.

My favorite part of that link is the statement that the webpage for the Chrome Browser was penalized for a sponsored post penalty.

http://searchengineland.com/google-chrome-page-will-have-pagerank-reduced-due-to-sponsored-posts-106551

If you have the .com, you win.  If there is a popular .net, you will get some spillover traffic for your .com.  But if you own "HotLawyer.com", I wouldn't expect you would lose much traffic to "HotLawyer.tv".  Domain brokers can be annoying with their constant offers.

Yes, and typically on every page if clients do not mind.  They were also built up over time, and many clients don't host with me.

I believe the story would be different if we just built 100 new sites tomorrow on the same ip address, and they all had a link to the same one site.

I think Google penalizes what looks like obvious spamming.  These sites are all legitimate. If there would be a gain to use dedicated IP addresses, I doubt it would be worth the cost for me.

My experience is a dedicated IP is not a great boost, nor worth the money if SEO is the only reason to pay for it - if you are only working with one domain.  If you have 500 domains all on the same IP, and they all have a link to your site, that will probably get a Google penalty.

I am more of a web developer than an SEO expert, and I resell hosting.  Hundreds of accounts spread around about 10 ip addresses on only three servers.  Most have links to my web design site, and it seems to avoid being penalized.

Yes, purchase your name for the 10 years max.  Age of domain seems to help one of my clients a lot.  The ideas is a search engine will have a greater 'trust' in a domain that is going to be around for a while than one that may only be here for a year.

A competitor to one of my clients split into to companies (and two websites).  They had invested a lot of money promoting their original domain, and there were loads of good links in.  They 301 redirected all pages in their original site to their original home page.  That page is still up but has an explanation of the split and one link to each of the two new companies.

I believe their attempt was to take all the "linkjuice" and split it evenly between the two companies.  Then it is regular SEO on the new sites.

It was probably important than the old name stays up, and the new companies have new names.

Are you the JMHHACKER that will add your GOOGLE plus id to a special circle then share it with my 12700 followers, called the snowball circle look it up for $5?

If not then you are seeing those big numbers because of someone else.  Just Google JMHHACKER, and you will see a lot of results on web pages, social media, and on the site that anyone can sell anything for $5, where JMHHACKER is selling the aforementioned plus in a circle.

It should make no difference, because Google will consider /funny-memes/SOME_RANDOM_IMAGE as your homepage.  But people would link to just chucklebot.com, not that long url.

Why not just serve the content from /funny-memes/SOME_RANDOM_IMAGE on the domain name.. Google would actually like updated content on the page, and if people build links, they will build links.

My clients demand a google + button, and I'm confided I am the only person who has clicked one.

Google+ is great.  It is better than facebook, but nobody wants to switch. It will go the way of Google Wave

Google Wave was even better, but noone dropped email and started using it.

What makes you say this?

In my LinkedIn profile, I see this code in the link to my website:

target="_blank" title="New window will open">HandsomeWeb

Because that automatically redirects, and there is no "nofollow", it should work.

Si tanto la versión www y el trabajo de la versión no-www en su sitio, el "Crawl Diagnostics Summary" va a reportar como dos páginas diferentes.

Utilice esta en el archivo htaccess. (en Apache):

Options +FollowSymlinks
RewriteEngine on

RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]

I would insist on a typical description tag.  That may work, but I, and you, know the typical description tag works.  If someone has a new way of doing something that changes something you know works, you should play it safe unless there is a clear gain.

It sounds that you did things correctly (especially testing a few pages first).  Here are a couple of things for your consideration:

Google Takes Time on 301 Redirects

When I did a change of URLs on a site with about 200 pages last month.  The rankings and traffic tanked for two weeks, then reappeared.  It may be taking time for Google to move the value of your version 2 pages to the value of your version 1 page.  You will just have to wait and see.

Duplicate Content Can be Addressed this Way:

If you have three same-content pages, you can keep them all and put a canonical tag on all three that reference version one as the prefered copy.

When I faced a situation with several hundred pages, I decided to to only list the most important ones.  I determined the important ones by there presence in Google and the import of the page content.

I first Googled "site:www.example.com" to get a good idea of what was indexed.

I used Analytics to see if any pages were entry pages.  If a page gets no hits as an entry page, the 301 redirect is never needed.

I made a list of about 100 redirects, then made the 404 error page a slight variation of my homepage.

Now if you have any pages that have links in, you will need to maintain those redirects.

Check in the root directory for a file called .htaccess

A typical way of listing the 404 redirects in the file is like this:

ErrorDocument 404 /404-error-page.php

If you don't see a line that starts with "ErrorDocument" then Joomla or Virtuemart are causing the problem.  If it is an old version of Joomla, it needs to be updated anyway for security reasons.  If the line seems messed up in the .htaccess file, you can at least send it to a working page like this:

ErrorDocument 404 /index.php

Maybe that will at least send it to the front page.

It is probably not as valuable to you because you know what to check for.  You probably now that the results you get from WordPress with a typical theme and now SEO plugins is not ideal, so you know what to look for in an SEO plugin.  I think there are a lot of positive feelings about Thesis because it is stylable and does a decent job with SEO matters.

I think there are some good SEO plugins that can make any WordPress site have solid SEO. Here is what I look for: Number one thing you need is something to rewrite those titles and descriptions, Number two: handle canonicalization, Number three noindex on archives (usually).

I like the guest blogging idea for two reasons.  One, it builds links, and two, it allows me to add content to a lot of blogs that are really interested in growing a lot of good content.  But I often read articles that give credit to another article, that give credit to another article.

I have been offered plenty of documents for client blogs, but I am worried that at some point in the future Google will decide all this guest blogging is similar to link trading and selling.

What does everyone else think of guest blogging?

Would it be less time to get a new domain name and start over?

I lose sleep at night worrying because I posted in the World Rock Paper Scissors Associations Website's forum a comment about a bankruptcy lawyer.

There was a time when we had domain names, but there was no world wide web (am I old?).  It only made sense when we added the world wide web that we gave a sub-domain (www) to our world wide web server, after all that was what we did with our gopher server.  But everyone that says, choose your favorite, is correct.  It will make no difference.

Note: I had email before I had a mouse.

Maybe Google includes all sub-domains.  I just tested my site, and got the following results.

site:handsomeweb.com 340 results (all have www)

site:www.handsomeweb.com 231 results (all have www)

The difference is the first query includes pages located at:blog.handsomeweb.com

You will also need a redirect for index.php (or index.html or index.aspx) to www.plugnbuy.com.

Your site has not yet launched, so you don't need to panic yet.

Search the Joomla Extensions directory and choose one of the canonicalization extensions.  Just search for "Canonical"

These extensions will add a canonical meta tag to the pages to say which one is most important.  This saves all the link juice to just one page, and will clear up most of your duplicate pages.

Hard to be sure without digging in your site, but here are some thoughts.

WordPress just updated to 3.4.1, did you? Is there an updated to the Genesis Framework or the Pretty Young Thing Theme? Both of the above should be indicated in your WordPress Dashboard.

Did you delete the post on accident? It may have had no content, but would have the slug "fetal-doppler-questions-and-answers"?

Do the posts under your faq's have the correct parent file listed?

Did you change the slug from "FAQ" to "fetal-doppler-questions-and-answers"?  If so, change the slug back to "FAQ" or whatever it was. You might have done this for SEO reasons.  If you changed the slug for the page, and want it used for your FAQ, try this:

DO THIS ONLY IF YOU CHANGED THE SLUG:

If the slug was FAQ, there may be a file named FAQ.php that tells WordPress to layout the page with slug "faq" using that file.  So if you changed the slug from "FAQ" to "fetal-doppler-questions-and-answers", just change the file from "FAQ.php" to ""fetal-doppler-questions-and-answers.php" (CASE IS IMPORTANT.).  Note, the file may be in the parent theme (Genesis).

Back up anything your about to change, and good luck.

The issue is www.EXAMPLE.com and EXAMPLE.com are considered two different websites, and Google may split the links in if people are linking to both versions.  A 301 redirect tells Google to assume all links are pointed at one version.

Your Question: I can see that it doesn't matter whether you type in 'www' or not in the url for a wordpress site, what is going on in the back end that allows this?

My Answer: This is not WordPress, it is your web host.  Most LAMP webhosts will automatically server your website with our without "WWW".  WordPress will create the links on the pages it creates to the one specified in your settings, but the site will come up weather or not you use "WWW."

To Address the Concern: Because you are using WordPress, you are probably on Apache, so add this to your .htaccess file in the root directory.

After:

END WordPress

Add:

Rewrite all old filenames RewriteEngine on

Options +FollowSymlinks
rewritecond %{http_host} ^EXAMPLE.com [nc] rewriterule ^(.*)$ http://www.EXAMPLE.com/$1 [r=301,nc]

Test with and without "WWW." Test with a different browser.

Yes, most definitely.  I just did the exact thing.  I moved a site that had originally been on asp classic, then moved to php, now to word press.  The .asp pages were being processed as php by the server, and there were hundreds of pages.  Within two weeks of moving site to WordPress and doing the redirects I saw immediate ranking results.  Here are just a few redirects, the way I was making them:

redirect 301 /about-fort-worth-personal-injury-lawyer.php /about-for . . .
redirect 301 /arlington-personal-injury-lawyer-locations.php /arlingto . . .
redirect 301 /injury-law-news.php /injury-law-news/
redirect 301 /asbestos-claim.asp /asbestos-claim/
redirect 301 /auto-accident.asp /auto-accident/
redirect 301 /burns.asp /burns/
.
.
.

Here are the steps I took to save time.

• I created an xml sitemap at one of those free online sitemap creators and downloaded as CSV.
• Used the list in php script I wrote to scrape the text from each page on the old site and insert into the WordPress database using the file name as title (replacing - with space) and droping .asp or .php
• I recreated the redirects in Exel by combining a column of the old filenames and the newly created ones. Cut and pasted.
• The new url's were in Google in about 10 days.

301 redirect is a permanent redirection.  If you set up a 301 redirect and a search engine requests the page, the search engine is sent a reply that says the page has permanently moved to a different location.  So Google will consider the new page as the one to be indexed.  Google will also transfer the value of any links to hp.domain.com to www.domain.com/hp.

In most situations, I believe it is best to optimize one domain than several.  Search engines will consider a subdomain as a complete separate domain.  And yes www.domain.com are considered two different domain names (although I suspect Google tries to sort that one out). Using the 301 redirects to the folder transfers the value of the links of the sub domain to the file in the folder, which is also a link in to a place on the domain www.domain.com.

Search how to do redirects, there are many tutorials for different platforms.  It is not difficult.  However if you are using one of those free hosting sites, you are not going to have any luck.

I like subdomains for usability, but maintain 301 redirects to folders.  Humans may prefer the subdomain, so they are useful.

hp.domain.com has a 301 redirect to www.domain.com/hp

Search engines will consider hp.domain.com a different domain than www.domain.com.

I do this most commonly for mobile.

m.domain.com has a 301 redirect to www.domain.com/m

Yes, you would add the canonical link element:

to the 20 pages that are the same as your home page.  But I think they are all the same page, so you don't have to look far.  The pcsid looks like a session id, so if you can add the canonical link element to index.php, it will appear in all displays of the home page.  It is OK if the canonical link element on a page points to itself.

Notice that index.php is used for search results and shopping cart pages also.  So adding it to index.php may add it to all your search pages and cart pages. But do you want those pages indexed?  If not, then the element is OK on these pages.

WARNING

Your product pages do not display index.php, but I am assuming they are dynamically generated.  If they are, you may end up with the canonical link element on every page of your site.  If your software can't handle that differently, you will be better off without the canonical link element.

Use an XML Sitemap

NOTE: Use an XML sitemap, and submit it on Google Webmaster Tools (and similar at other engines).  If the URL is on the sitemap, it should get preference over a URL not on the sitemap.

Currently on Google

You sites listings don't show any pcsid numbers, so the duplicate content issue may not be a big problem.  You do, however, want credit when someone links to your page and add a pcsid in their linking url.

If your shopping cart provider does not have a way for you to fix this, urge them to add it.
