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.

URL structure - Page Path vs No Page Path
We are currently re building our URL structure for eccomerce websites. We have seen a lot of site removing the page path on product pages e.g. https://www.theiconic.co.nz/liberty-beach-blossom-shirt-680193.html versus what would normally be https://www.theiconic.co.nz/womens-clothing-tops/liberty-beach-blossom-shirt-680193.html Should we be removing the site page path for a product page to keep the url shorter or should we keep it? I can see that we would loose the hierarchy juice to a product page but not sure what is the right thing to do.

Breadcrumbs versus in context link
Hi, I remember reading that links within the text have more value than breadcrumbs links for example because in context links are surrounded by the right content (words) but google search engine optimisation starter guide says breadcrumbs are good, so which one is recommended ? Thank you,

Null Alt Image Tags vs Missing Alt Image Tags
Hi, Would it be better for organic search to have a null alt image tag programatically added to thousands of images without alt image tags or just leave them as is. The option of adding tailored alt image tags to thousands of images is not possible. Is having sitewide alt image tags really important to organic search overall or what? Right now, probably 10% of the sites images have alt img tags. A huge number of those images are pages that aren Thanks!

Ecommerce: A product in multiple categories with a canonical to create a ‘cluster’ in one primary category Vs. a single listing at root level with dynamic breadcrumb.
OK – bear with me on this… I am working on some pretty large ecommerce websites (50,000 + products) where it is appropriate for some individual products to be placed within multiple categories / sub-categories. For example, a Red Polo T-shirt could be placed within: Men’s > T-shirts >
Intermediate & Advanced SEO | | AbsoluteDesign
Men’s > T-shirts > Red T-shirts
Men’s > T-shirts > Polo T-shirts
Men’s > Sale > T-shirts
Etc. We’re getting great organic results for our general T-shirt page (for example) by clustering creative content within its structure – Top 10 tips on wearing a t-shirt (obviously not, but you get the idea). My instinct tells me to replicate this with products too. So, of all the location mentioned above, make sure all polo shirts (no matter what colour) have a canonical set within Men’s > T-shirts > Polo T-shirts. The presumption is that this will help build the authority of the Polo T-shirts page – this obviously presumes “Polo Shirts” get more search volume than “Red T-shirts”. My presumption why this is the best option is because it is very difficult to manage, particularly with a large inventory. And, from experience, taking the time and being meticulous when it comes to SEO is the only way to achieve success. From an administration point of view, it is a lot easier to have all product URLs at the root level and develop a dynamic breadcrumb trail – so all roads can lead to that one instance of the product. There's No need for canonicals; no need for ecommerce managers to remember which primary category to assign product types to; keeping everything at root level also means there no reason to worry about redirects if product move from sub-category to sub-category etc. What do you think is the best approach? Do 1000s of canonicals and redirect look ‘messy’ to a search engine overtime? Any thoughts and insights greatly received.0 -
High resolution (retina) images vs load time
I have an ecommerce website and have a product slider with 3 images. Currently, I serve them at the native size when viewed on a desktop browser (374x374). I would like to serve them using retina image quality (748px). However how will this affect my ranking due to load time? Does Google take into account image load times even though these are done asynchronously? Also as its a slider, its only the first image which needs to load. Do the other images contribute at all to the page load time?

301 vs 410 redirect: What to use when removing a URL from the website
We are in the process of detemining how to handle URLs that are completely removed from our website? Think of these as listings that have an expiration date (i.e. http://www.noodle.org/test-prep/tphU3/sat-group-course). What is the best practice for removing these listings (assuming not many people are linking to them externally). 301 to a general page (i.e. http://www.noodle.org/search/test-prep) Do nothing and leave them up but remove from the site map (as they are no longer useful from a user perspective) return a 404 or 410?

Canonical VS Rel=Next & Rel=Prev for Paginated Pages
I run an ecommerce site that paginates product pages within Categories/Sub-Categories. Currently, products are not displayed in multiple categories but this will most likely happen as time goes on (in Clearance and Manufacturer Categories). I am unclear as to the proper implementation of Canonical tags and Rel=Next & Rel=Prev tags on paginated pages. I do not have a View All page to use as the Canonical URL so that is not an option. I want to avoid duplicate content issues down the road when products are displayed in multiple categories of the site and have Search Engines index paginated pages. My question is, should I use the Rel=Next & Rel=Prev tags on paginated pages as well as using Page One as the Canonical URL? Also, should I implement the Canonical tag on pages that are not yet paginated (only one page)?

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?
