Link juice from subdomain
-
Does having a blog on a subdomain as opposed to an extension of the root domain add or subtract to improving SEO on the root domain? For eg : what's better, HTTP://blog.durbansouthtoyota.co.za Or HTTP://www.durbansouthtoyota.co.za/blog When the www is the actual main site. Thanks!

You'll absolutely want to get the blog moved to the subdirectory. Tell your developers they must use 301 redirects to point the traffic from the old subdomain pages to the new location. As long as the blog's site structure and URLs remain the same, that will be a pretty straightforward redirect to write.
Once they've done the redirect, test by going to a bunch of the old page addresses and making sure you end on the new pages.
Also use a header-checking tool on the new pages to confirm that it's actually showing that 301 redirect was used (not a 302, for example)
The sooner you do this the better, so that new incoming links will be pointing directly to the new location instead of being redirectd through the old location.
if you want best bang for the buck, check for the strongest links that currently point to the old site and see if you can get their webmasters to update them to point to the new URLs. Even pages that are redirected don't pass 100% of their authority through the 301 to the new page, and there is evidence to indicate that the 301s pass less authority as they age.
All good reasons to get the move done as soon as practical.
Good luck!

P.S. If your blog has a name that people may begin to recognize & remember (ie that is different from the site name) strongly consider naming the folder /the-blog-name instead of just /blog. Every bit of distinctiveness helps!

Hey,
Thanks for the reply. My bad. After posting that question, I noticed from the related posts, that this has been dealt with previously, and basically most people lean towards the sub-folder method.
I have a problem since we have already launched our blog on the subdomain.
I am talking to our developers to consider moving it to the sub-folder setup. Is there a recommended method, to take care of all links to the old sub-domain - blog.durbansouthtoyota.co.za? I'm guessing some sort of re-direct right? I need to pass this info to our developers.
Thanks!

I prefer putting the blog in a subdirectory rather than a subdomain for SEO. The search engines treat subdomains as a completely separate site so any backlinks you get pointed to blog.domain.com will not benefit www.domain.com's SEO whereas links pointing to www.domain.com/blog will.
Here is a great blog post for more details - http://www.agent-seo.com/blogging/seo-subdomain-vs-subdirectory/,
I've pasted a few highlights below -
**Subdirectory **
This situation for me is the most ideal from an SEO standpoint. I prefer to use a subdirectory (or “subfolder”) over a subdomain or external site any day.
Matt Cutts agrees with me:
“My personal preference on subdomains vs. subdirectories is that I usually prefer the convenience of subdirectories for most of my content. A subdomain can be useful to separate out content that is completely different. Google uses subdomains for distinct products such news.google.com or maps.google.com, for example. If you’re a newer webmaster or SEO, I’d recommend using subdirectories until you start to feel pretty confident with the architecture of your site. At that point, you’ll be better equipped to make the right decision for your own site.”
Rand Fishkin agrees with me too, but does go on to detail compelling usage examples for subdomains:
“Starting a blog? I almost always recommend yoursite.com/blog over blog.yoursite.com.”
**Subdomain **
This is the second best option in my opinion for SEO. A subdomain is basically a separate or third-tier website that just so happens to be residing off of the root domain. Search engines typically view them as wholly separate entities. I would only use this if the blog was completely separate to your services (or if your site infrastructure does not allow you to add blogging software to the root domain).

Building an Industry Resource List w Links to Competitors
Hi folks. I'm working on a B2B e-commerce site in a very commoditized space. It's very technical and longtail-- several thousand product pages and of those, over 1,000 landing pages per month, when visitors find products. Most items we sell are only bought once or twice per year. Many won't even be bought in a given year. So it's tough to invest a lot on a given page, but we chip away at it. We don't have many non-product pages. To date, we've grown with solid on-page SEO for products and good customer service. I'm adding a resource section to include helpful articles and definitions of technical terms. Also, since good sources of products can be so hard to find (we literally have customers like NASA googling for parts), I would like to build an industry guide of sorts. It would include manufacturers, master distributors, distributors and resellers (like our site). To be a good list, it only makes sense to include my competitors. It's likely very few people will actually ever see this page, but I figure more deep content with lots of highly relevant links is good for raising DA, especially because it could become a page others want to link to. I haven't found a comparable resource in the 4 years I've been working on this project. Any reason I should not do this? Any pitfalls I should be aware of? Thank you!

Why is the blog link so often found in the footer?
Hello, Can someone tell me please why are the links to a site's blog not displayed prominently? Why are they hidden away in the footer? Wouldn't making the link to the blog more visible increase traffic?

I have just come across a few blogs on a website that have outbound links that open in the browser window (and therefore direct people off site to these links) (there are also other outbound links that open in a new window)- is there a quick and easy way to check which outbounds links open in a new window and which open in the browser window? Much obliged Liam

Tracking Down Rogue Spam Links
In Feb, 2015 www.mommyupgrade.com site received the following notification in GWT: http://www.mommyupgrade.com/: Suspected hackingFeb 4, 2015
Content Development | | hammia
Google has detected that some of your pages may contain hidden text or cloaking, techniques that are outside our Webmaster Guidelines.
Specifically, we detected that your site may have been modified by a third party. Typically, the offending party gains access to an insecure directory that has open permissions. Many times, they will upload files or modify existing ones, which then show up as spam in our index.
Sample URLs:At that time, the site was checked by the host and site owner and any suspicious links removed. We thought the problem was resolved until a MOZ crawl on March 22 which highlighted a number of hack links again. This is the link format: http://www.mommyupgrade.com/?p=online-slots All are related to gambling, casinos and slots. To find the links, we downloaded the MOZ crawl report and found that all the links were referred from this page: http://www.mommyupgrade.com/how-to-make-rainbow-lollipop-cookies/ Searching that post shows no sign of links to the rogue pages. I would really appreciate some advice on how to find the source of these links and delete them from this site once and for all. Also, please explain how it is possible for a post or page to refer to another page without that link showing up in the code? (Is this some black hat technique that I need to know about in order to protect my sites?) Also... at the moment Google Webmaster Tools are not reporting any security issues for this site. Any help appreciated.0 -
Is there an upper bound on the number of links an url might get in a day?
There are link spammers and programs like GSA and others, that automate linkbuilding, and I was wondering if anybody ever had a penalty because a page on his site is getting too many references (links). I am not talking about spamming here. So provided that the links are coming from relevant, unique sources, but you do an over excessive campaign, and you seem to be getting too many backlinks, can it negatively affect SEO? Alternatively: is there an upper bound on the number of links you try to build in a day when you are doing linkbuilding?

Too many links on page?
Hello, Can my rankings suffer if some of my inner pages have too many links/anchor text? Or would link juice just stop being passed after X amount of links? I have content on these inner pages, and it all flows. Thanks!
