Canonical tag + HREFLANG vs NOINDEX: Redundant?
-
Hi,
We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory
We are now opening indexing to double faceted page like category + brand and the new tag structure would be:
For any other facet we're including a "noindex, follow" meta tag.
1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"?
2. Is the x-default redundant?
Thanks for any input.
Cheers
WMCA

It depends a bit on your setup and how easy/difficult it is to implement the tags but a couple of things to have in mind:
NOINDEX, FOLLOW should still mean the hreflang tags on the page are seen and followed even though the page in question is not indexed, the page needs to be parsed for the crawler to read the meta tag.
If you are not facing some serious issue with crawling and your system automatically adds the canonical and hreflang tags then I would leave them as is even on the no indexed pages (you might for example want to start indexing the french pages but not the english pages of certain cat/brand etc combinations and the hreflang tags might help speed recognition of this kind of change to the crawlers).
For the x-default my understanding is it is mainly for use in a multinational setup with default landing pages and or auto lang/region redirections and your url suggests your are aiming at Canada (and maybe USA) and only for en/fr so my understanding is it might not be really crucial in this case. Check out this page for some more details.

If the page isn't indexed, then neither a hreflang or canonical URL makes any sense, as search engines would ignore that page alltogether.

Should I disable the indexing of tags in Wordpress?
Hi, I have a client that is publishing 7 or 8 news articles and posts each month. I am optimising selected posts and I have found that they have been adding a lot of tags (almost like using hashtags) . There are currently 29 posts but already 55 tags, each of which has its own archive page, and all of which are added to the site map to be indexed (https://sykeshome.europe.sykes.com/sitemap_index.xml). I came across an article (https://crunchify.com/better-dont-use-wordpress-tags/) that suggested that tags add no value to SEO ranking, and as a consequence Wordpress tags should not be indexed or included in the sitemap. I haven't been able to find much more reliable information on this topic, so my question is - should I get rid of the tags from this website and make the focus pages, posts and categories (redirecting existing tag pages back to the site home page)? It is a relatively new websites and I am conscious of the fact that category and tag archive pages already substantially outnumber actual content pages (posts and news) - I guess this isn't optimal. I'd appreciate any advice. Thanks wMfojBf

Canonical Chain
This is quite advanced so maybe Rand can give me an answer? I often have seen questions surrounding a 301 chain where only 85% of the link juice is passed on to the first target and 85% of that to the next one, up to three targets. But how about a canonical chain? What do I mean by this:? I have a client who sells lighting so I will use a real example (sans domain) I don't want 'new-product' pages appearing in SERPS. They dilute link equity for the categories they replicate and often contain identical products to the main categories and subcategories. I don't want to no index them all together I'd rather tell Google they are the same as the higher category/sub category. (discussion whether a noindex/follow tag would be better?) If I canonicalize new-products/ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 to /ceiling-lights-c1/kitchen-lighting-c17/kitchen-ceiling-lights-c217 I then subsequently discover that everything in kitchen-ceiling-lights-c217 is already in /kitchen-lighting-c17 and I decide to canonicalize those two - so I place a /kitchen-lighting-c17 canonical on /kitchen-ceiling-lights-c217. Then what happens to the new-products canonical? Is it the same rule - does it pass 85% of link equity back to the non new-product URL and 85% of that back to the category? does it just not work? or should I do noindexi/follow Now before you jump in: Let's assume these are done over a period of time because the obvious answer is: Canonicalize both back to /ceiling-lights-c1/kitchen-lighting-c17 I know that and that is not what I am asking. What if they are done in a sequence what is the real result? I don't want to patronise anyone but please read this carefully before giving an answer. Regards Nigel Carousel Projects.

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!

Proper Title Tags for ecommerce
In terms of E-commerce title tags. We are a manufacturer of our own clothing products. We are new to the SEO landscape so if this question is an obvious answer, then i apologize for wasting any one times in advance. We Manufacture our own clothing. Each item has a name. The names are American womens names such as amanda or lori or jenniffer etc. When we create the title tag for them should we include the name of the item itself at the beginning or end. For example should it be Item Name - Keyword - Keyword - Brand Name(aka manufacturer) or Keyword - Keyword - Item Name - Brand Name (aka manufacturer) The reason we ask this is because we think it would be a waste to rank for actual American names such as Jennifer and Jessica. All that we have read on Moz suggests that it seems to be better to have pertinent keywords in the beginning of the title as opposed to the end. In terms of our brand name we already rank number 1 for every combination of our brand. So we would like to start picking up traffic for the different product types we sell and there respective synonyms. Not sure if i am making any sense. Sorry in advance, and any help is very very much appreciated.

Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0 -
Partial duplicate content and canonical tags
Hi - I am rebuilding a consumer website, and each product page will contain a unique product image, and a sentence or two about the product (and we tend to use a lot of the same words in different ways across products). I'd like to have a tabbed area below the product info that talks about the overall product line, and this content would be duplicate across all the product pages (a "Why use our products" type of thing). I'd have this duplicate content also living on its own URL's so they can be found alone in the SERP's. Question is, do I need to add the canonical tag to this page, since there's partial duplicate content on the product pages? And if I did that, would my product pages go un-indexed?? I understand how to handle completely duplicated content, it's the partial duplicate that I'm having difficulty figuring out.

Best way to implement canonical tags on an ecommerce site with many filter options?
What would be the best way to add canonical tags to an ecommerce site with many filter options, for example, http://teacherexpress.scholastic.com? Should I include a canonical tag for all filter options under a category even though the pages don't have the same content? Thanks for reading!

NOINDEX or NOINDEX,FOLLOW
Currently we employ this tag on pages we want to keep out of the index but want link juice to flow through them: <META NAME="ROBOTS" CONTENT="NOINDEX"> Is the tag above the same as: <META NAME="ROBOTS" CONTENT="NOINDEX,FOLLOW"> Or should we be specifying the "FOLLOW" in our tag?
