HREFLANG for multiple country/language combinations
-
We have a site setup with English, German, French, Spanish and Italian. We offer these languages for every European country (over 30). Thus, there are 150 + different URL combinations, as we use the /country/language/ subdirectory path.
Should I list out every combination in hreflang?Or should I simply choose the most applicable combinations (/de/de and fr/fr, etc.)? If we go the latter path, should I block google bot from crawling the atypical combinations?
Best,
Sam

Hi Sam,
Apologies for the slow response. Your question slipped through the net.
This is an interesting case!
In an ideal world, you'd specify the relationship between all of those pages, in each direction. That's 150+ tags per page, though, which is going to cause some headaches. Even if you shift the tagging to an XML sitemap, that's a _lot _of weight and processing.
Anecdotally, I know that hreflang tagging starts to break at those kinds of scales (even more so on large sites, at that kind of scale, when the resultant XML sitemaps can reach the size of many gigabytes, or when Google is crawling faster than it's processing the hreflang directives), and so tagging everything isn't going to be a viable approach.
I'd suggest picking out and implementing hreflang for _only _the primary combinations*, as you suggest, and reducing the site-wide mapping to the primary variant in each case.
- You might consider that there may be cases where the valuable/primary combinations aren't just the /xx/xx/ or _/yy/yy/ _versions and that there might be some examples of varying country/language combinations which are worth including.
For the atypical variants, I think that you have a few options:
-
Use meta robots (or x-robots) tags to set noindex attributes. This will keep them out of the index, but doesn't guarantee that you're effectively managing/consolidating value across near duplicates - you may be quietly harming performance without realising it, as those pages represent points of crawl and value wastage/leakage.
-
Use robots.txt to prevent Google from accessing the atypical variants. That won't necessarily stop them from showing up in search results, though, and isn't without problems - you risk you creating crawl dead-ends, writing off the value of any inbound links to those pages, and other issues.
-
You use canonical URLs on all of the atypical variations, referencing the nearest primary version, to attempt to consolidate value/relevance etc. However, that risks the wrong language/content showing up in the wrong country, as you're explicitly _un_optimising the location component.
I think that #1 is the best approach, as per your thinking. That removes the requirement to do anything clever or manipulative with hreflang tagging, and fits neatly with the idea that the atypical combinations aren't useful/valuable enough to warrant their own identities - Google should be smart enough to fall back to the nearest 'generic' equivalent.
I'd also take care to set up your Google Search Console country targeting for each country-level folder, to reduce the risk of people ending up in the wrong sections.

Multiple sub-category of the same name ? does that effect SEO
Hello, If I have multiple sub-category of the same name ? does that affect SEO for example I have the following category structure? domain/bmw/series5/2006.html domain/bmw/series5/2007.html .. etc domain/bmw/series3/2007.html domain/bmw/series3/2006.html ..etc domain/Acura/cl/2006.html domain/Acura/cl/2007.html .. etc I do use canonical url because I may have the same product in multiple categories but my question does google penalize me because I have the same (year) url key for multiple categories even though I use canonical url ? do I have any advantage in masking them filters vs sub-category from SEO point of view ? specially my goal is to have different meta title and meta description for each sub category ?

What is your hypothesis why Panda/Penguin recoveries happen over months after an algorithm update rather than over night?
We have experienced many scenarios were ranking recoveries from clear Panda and Penguin penalties on our sites don't necessarily happen with the launch of a Panda/Penguin update but instead trickle back in over weeks and months after a confirmed algo update. A good example is shown in the image which shows a panda recovery for a high volume keyword. What is your theory why these ranking recoveries happen over weeks vs instantly? qCWliLF

What is the impact of HTTP/2 on SEO ?
I think it's good for the user experience and speeds up websites, especially if your site has a lot of requests. But i'm not sure if there are other side effects, and if there's an impact on SEO or technical configuration. Most of my websites are built with Wordpress, some with Joomla.

Do panda/penguin algorithm updates hit websites or just webpages ?
If I have a website that been affected by the panda/penguin update, do bad links affect the entire site or just the page the bad link(s) are linked to? If it is the latter and penguin/panda actually affect webpages, not websites (as is the common reference/conception), then wouldn't simply creating a new URL, targeting this new URL, shifting meta-tags and restarting link-building efforts again (this time using the right quality strategies) be a really common-sense approach instead of the tediousness of the disavow approach that so many go down?

Is it ok to repeat part of a meta-description across multiple pages?
For example, what if I was to conclude each meta-description tag with the line... "Free shipping for orders over $90." The rest of the meta-description tag on every page is unique, but the last sentence would be the same or at least similar. Thoughts?

Local SEO url format & structure: ".com/albany-tummy-tuck" vs ".com/tummy-tuck" vs ".com/procedures/tummy-tuck-albany-ny" etc."
We have a relatively new site (re: August '10) for a plastic surgeon who opened his own solo practice after 25+ years with a large group. Our current url structure goes 3 folders deep to arrive at our tummy tuck procedure landing page. The site architecture is solid and each plastic surgery procedure page (e.g. rhinoplasty, liposuction, facelift, etc.) is no more than a couple clicks away. So far, so good - but given all that is known about local seo (which is a very different beast than national seo) quite a bit of on-page/architecture work can still be done to further improve our local rank. So here a a couple big questions facing us at present: First, regarding format, is it a given that using geo keywords within the url indispustibly and dramatically impacts a site's local rank for the better (e.g. the #2 result for "tummy tuck" and its SHENANIGANS level use of "NYC", "Manhattan", "newyorkcity" etc.)? Assuming that it is, would we be better off updating our cosmetic procedure landing page urls to "/albany-tummy-tuck" or "/albany-ny-tummy-tuck" or "/tummy-tuck-albany" etc.? Second, regarding structure, would we be better off locating every procedure page within the root directory (re: "/rhinoplasty-albany-ny/") or within each procedure's proper parent category (re: "/facial-rejuvenation/rhinoplasty-albany-ny/")? From what I've read within the SEOmoz Q&A, adding that parent category (e.g. "/breast-enhancement/breast-lift") is better than having every link in the root (i.e. completely flat). Third, how long before google updates their algorithm so that geo-optimized urls like http://www.kolkermd.com/newyorkplasticsurgeon/tummytucknewyorkcity.htm don't beat other sites who do not optimize so aggressively or local? Fourth, assuming that each cosmetic procedure page will eventually have strong link profiles (via diligent, long term link building efforts), is it possible that geo-targeted urls will negatively impact our ability to rank for regional or less geo-specific searches? Thanks!
