Silo vs breadcrumbs in 2015
-
Hi ive heard silos being mentioned in the past to help with rankings does this still apply?
and what about breadcrumbs do i use them with the silo technique or instead of which ones do you think are better or should i not be using these anymore with the recent google updates?

great thanks ill give that a go

It's been a while since I've used WP, but if you use posts (or posts and pages), you will have a major silo and duplicate content problem with blog category pages.
The way to solve this is to go to the section where you set up your post categories, and set the slug to be identical to your category page. For example, if you have a page category with the slug "blue-widgets", set the post category slug to "blue widgets". This makes the category page the parent for posts in that category.
There are also some adjustments that you will need to make to your URLs removing "/category/ from your URLs. I've done it, and it's pretty easy. Maybe another poster could give you the specifics.

great thanks very informative reply, i've started using wordpress for most of my sites now, is siloing easy enough to do in wordpress?

Silos will always work. It's not some trick - it's how Google works. Here's a very simplified explanation as to why...
Let's say that I have an eCommerce site, and I sell lawnmowers and Plywood. Let's also say that the Lawnmowers category page has a theoretical 100 points of link juice. Lets also say that the site sells 2 lawnmowers - the Fubar 2000 and the Toecutter 300. If the lawnmower category page only links to the Fubar 2000 and the Toecutter 300 pages, the category page will push 45 points of link juice to each page (pages can pass on +/-90% of their link juice, and 90/2=45).
Both pages will receive almost the full 45 point benefit because the pages are relevant to the category page.
If the Lawnmower category page instead only has 1 link to the Plywood page, the Lawnmower category page would push 90 points of link juice to the plywood page. But, the Plywood page would not receive the full benefit of the 90 points, because Lawnmowers and Plywood don't share much relevance. In this case, Google would heavily discount the 90 points, so that the Plywood page might only get the benefit of 30 points. Think of it as a leaky hose.
What happens to the other 60 Points of Link Juice? It gets dumped on the floor, and the site loses the ranking power of those 60 points.
Keep in mind that this is all theoretical, and that link juice comes in different flavors like apple, orange and prune, representing the different ranking factors (Trust, Authority, Topical Authority, Social Signals, etc.) . Orange might discount 90% while prune might only discount 10%. In this case, is there really a 67% link juice hit? Damned if I know, but I had to pick a number... This is all theoretical. I do know that link juice loss between pages that aren't relevant is dramatic. I also know that it is very possible to determine how your internal pages rank based on your internal link structure, and link placement on the page.
By siloing a website, I have seen rankings jump dramatically. Most websites hemorrhage link juice. Think of it as Link Juice Reclamation. The tighter you can build your silos, the less link juice gets dumped on the floor. By reclaiming the spilled link juice and putting it in the right places, you can dramatically increase your rankings. BTW, inbound links work in a similar fashion. If the Lawnmower page was an external site and linked to the Plywood page, the same discounts would apply. That's why it pays to get niche relevant backlinks for maximum benefit.
This in no way accounts for usability, and linking between silos can make sense to benefit end-users. Again, this model is probably overly simplified, and doesn't take into account Block Level Analysis, but the logic is sound. You can build spreadsheet models for link juice distribution factoring in Block level, discounts, etc. It's by no means accurate, but can give you a pretty good idea of where your link juice is going. You can model this on the old (and increasingly irrelevant) PageRank Algorithm. Pagerank is Logarithmic and it takes 8-9x as much link juice to move up in PR. If it takes 100 points of Link Juice to become a PR1, it takes 800-900 points to become a PR 2. Generally speaking a PR2 page, via links, can create roughly 7 to 75 PR1 pages, depending on how close the PR2 is to becoming a PR3.

Both is the way to go. Silos are essentially structuring your pages so that per topic, there is 1 master article and multiple supporting articles that link back to the master article. The topic only links to pages relevant to the topic and not other sections of the site.
You can use breadcrumbs in conjunction with a silo as the structure is suitable for them.

Schema Markup Validator vs. Rich Results Test
I am working on a schema markup project. When I test the schema code in the Schema Markup Validator, everything looks fine, no errors detected. However, when I test it in the Rich Results Test, a few errors come back.

How To Implement Breadcrumbs
Hi, I'm looking to implement breadcrumbs for e-commerce store so they will appear in the SERP results like the attached image. In terms of implementing to a site, would you simply add HTML to each page like this Google example? Which looks like this: Books › Science Fiction Award Winners Then is there anything you need to do, to get this showing in the SERPs results e.g. doing something in search console. Or do you just wait into google has crawled and hopefully starts showing in the SERPs results? Cheers. wn3ybMMOQFW98fNQkxtJkA.png [SERP results with bread crumbs](SERP results with bread crumbs)

Best Permalinks for SEO - Custom structure vs Postname
Good Morning Moz peeps, I am new to this but intending on starting off right! I have heard a wealth of advice that the "post name" permalink structure is the best one to go with however... i am wondering about a "custom structure" combing the "post name" following the below example structure: Www.professionalwarrior.com/bodybuilding/%postname/ Where "professional" and "bodybuilding" is my focus/theme/keywords of my blog that i want ranked. Thanks a mill, RO

Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Location.href vs href?
I just got off a Google Hangout with John Mueller and was left a little confused about his response to my question. If I have an internal link in a div like widgetwill it have the same SEO impact as widget John said that as you are unable to attribute a nofollow in an onclick event it would be treated as a naked link and would not pass pagerank but still be crawled. Can anyone confirm that I understood it correctly? If so should all my links that have such an onclickevent also have an html ahref in the too? Such as widget Many times it is more useful for the customer to click on any area of a large div and not just the link to get to the destination intended? Clarification on this subject would be very useful, there is nothing easily found online to confirm this. Thanks

Outbound link to PDF vs outbound link to page
If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

Schema.org Implementation: "Physician" vs. "Person"
Hey all, I'm looking to implement Schema tagging for a local business and am unsure of whether to use "Physician" or "Person" for a handful of doctors. Though "Physician" seems like it should be the obvious answer, Schema.org states that it should refer to "A doctor's office" instead of a physician. The properties used in "Physician" seem to apply to a physician's practice, and not an actual physician. Properties are sourced from the "Thing", "Place", "Organization", and "LocalBusiness" schemas, so I'm wondering if "Person" might be a more appropriate implementation since it allows for more detail (affiliations, awards, colleagues, jobTitle, memberOf), but I wanna make sure I get this right. Also, I'm wondering if the "Physician" schema allows for properties pulled from the "Person" schema, which I think would solve everything. For reference: http://schema.org/Person http://schema.org/Physician Thanks, everyone! Let me know how off-base my strategy is, and how I might be able to tidy it up.

Multiple stores & domains vs. One unified store (SEO pros / cons for E-Commerce)
Our company runs a number of individual online shops, specialised in particular products but all in the same genre of goods overall, with a specific and relevant domain name for each shop. At the moment the sites are separate, and not interlinked, i.e. Completely separate brands. An analogy could be something like clothing accessories (we are not in the clothing business): scarves.com, and silkties.com (our field is more niche than this) We are about to launch a related site, (e.g. handbags.com), in the same field again but without precisely overlapping products. We will produce this site on a newer, more flexible e-commerce platform, so now is a good time to consider whether we want to place all our sites together with one e-commerce system on the backend. Essentially, we need to know what the pros and cons would be of the various options facing us and how the SEO ranking is affected by the three possibilities. Option 1: continue with separate sites each with its own domains. Option 2: have multiple sites, each on their own domain, but on the same ecommerce system and visible linked together for the customer (with unified checkout) – on the top of each site could be a menu bar linking to each site: [Scarves.com] – [SilkTies.com] – [Handbags.com] The main question here is whether the multiple domains are mutually beneficial, particularly considerding how close to target keywords the individual domains are. If mutually benefitial, how does it compare to option 3: Option 3: Having recently acquired a domain name (e.g. accessories.com) which would cover the whole category together, we are presented with a third option: making one site selling all of these products in different categories. Our main concern here would be losing the ability to specifically target marketing, and losing the benefit of the domains with the key words in for what people are more likely to be searching for (e.g. 'silk tie') rather than 'accessories.' Is it worth taking the hit on losing these specific targeted domain names for the advantage of increased combined inbound links?
