Hreflang in vs. sitemap?
-
Hi all,
I decided to identify alternate language pages of my site via sitemap to save our development team some time. I also like the idea of having leaner markup.
However, my site has many alternate language and country page variations, so after creating a sitemap that includes mostly tier 1 and tier 2 level URLs, i now have a sitemap file that's 17mb. I did a couple google searches to see is sitemap file size can ever be an issue and found a discussion or two that suggested keeping the size small and a really old article that recommended keeping it < 10mb.
Does the sitemap file size matter? GWT has verified the sitemap and appears to be indexing the URLs fine.
Are there any particular benefits to specifying alternate versions of a URL in vs. sitemap?
Thanks,
-Eugene

I have always preferred in the sitemap because it keeps potential lines of code off your page. Everything helps when it comes to page speed.
However, if it's easier for you to put the tags on page, that's is completely valid. Do whatever is easiest to maintain and update.

First off if you want to keep the sitemap file, consider breaking it down to multiple files, one for each language/country etc...
Also FYI there are THREE methods, you can also add hreflang to the http header. This might be a good options as well to consider.

Sitemap generator which only includes canonical urls
Does anyone know of a 3rd party sitemap generator that will only include the canonical url's? Creating a sitemap with geo and sorting based parameters isn't the most ideal way to generate sitemaps. Please let me know if anyone has any ideas. Mind you we have hundreds of thousands of indexed url's and this can't be done with a simple text editor.

Canonical URL & sitemap URL mismatch
Hi We're running a Magento store which doesn't have too much stock rotation. We've implemented a plugin that will allow us to give products custom canonical URLs (basically including the category slug, which is not possible through vanilla Magento). The sitemap feature doesn't pick up on these URLs, so we're submitting URLs to Google that are available and will serve content, but actually point to a longer URL via a canonical meta tag. The content is available at each URL and is near identical (all apart from the breadcrumbs) All instances of the page point to the same canonical URL We are using the longer URL in our internal architecture/link building to show this preference My questions are; Will this harm our visibility? Aside from editing the sitemap, are there any other signals we could give Google? Thanks

What Happens If a Hreflang Sitemap Doesn't Include Every Language for Missing Translated Pages?
As we are building a hreflang sitemap for a client, we are correctly implementing the tag across 5 different languages including English. However, the News and Events section was never translated into any of the other four languages. There are also a few pages that were translated into some but not all of the 4 languages. Is it good practice to still list out the individual non-translated pages like on a regular sitemap without a hreflang tag? Should the hreflang sitemap include the hreflang tag with pages that are missing a few language translations (when one or two language translations may be missing)? We are uncertain if this inconsistency would create a problem and we would like some feedback before pushing the hreflang sitemap live.

When to Use Schema vs. Facebook Open Graph?
I have a client who for regulatory reasons cannot engage in any social media: no Twitter, Facebook, or Google+ accounts. No social sharing buttons allowed on the site. The industry is medical devices. We are in the process of redesigning their site, and would like to include structured markup wherever possible. For example, there are lots of schema types under MedicalEntity: http://schema.org/MedicalEntity Given their lack of social media (and no plans to ever use it), does it make sense to incorporate OG tags at all? Or should we stick exclusively to the schemas documented on schema.org?

Google Not Indexing XML Sitemap Images
Hi Mozzers, We are having an issue with our XML sitemap images not being indexed. The site has over 39,000 pages and 17,500 images submitted in GWT. If you take a look at the attached screenshot, 'GWT Images - Not Indexed', you can see that the majority of the pages are being indexed - but none of the images are. The first thing you should know about the images is that they are hosted on a content delivery network (CDN), rather than on the site itself. However, Google advice suggests hosting on a CDN is fine - see second screenshot, 'Google CDN Advice'. That advice says to either (i) ensure the hosting site is verified in GWT or (ii) submit in robots.txt. As we can't verify the hosting site in GWT, we had opted to submit via robots.txt. There are 3 sitemap indexes: 1) http://www.greenplantswap.co.uk/sitemap_index.xml, 2) http://www.greenplantswap.co.uk/sitemap/plant_genera/listings.xml and 3) http://www.greenplantswap.co.uk/sitemap/plant_genera/plants.xml. Each sitemap index is split up into often hundreds or thousands of smaller XML sitemaps. This is necessary due to the size of the site and how we have decided to pull URLs in. Essentially, if we did it another way, it may have involved some of the sitemaps being massive and thus taking upwards of a minute to load. To give you an idea of what is being submitted to Google in one of the sitemaps, please see view-source:http://www.greenplantswap.co.uk/sitemap/plant_genera/4/listings.xml?page=1. Originally, the images were SSL, so we decided to reverted to non-SSL URLs as that was an easy change. But over a week later, that seems to have had no impact. The image URLs are ugly... but should this prevent them from being indexed? The strange thing is that a very small number of images have been indexed - see http://goo.gl/P8GMn. I don't know if this is an anomaly or whether it suggests no issue with how the images have been set up - thus, there may be another issue. Sorry for the long message but I would be extremely grateful for any insight into this. I have tried to offer as much information as I can, however please do let me know if this is not enough. Thank you for taking the time to read and help. Regards, Mark Oz6HzKO rYD3ICZ

Canonical URLs and Sitemaps
We are using canonical link tags for product pages in a scenario where the URLs on the site contain category names, and the canonical URL points to a URL which does not contain the category names. So, the product page on the site is like www.example.com/clothes/skirts/skater-skirt-12345, and also like www.example.com/sale/clearance/skater-skirt-12345 in another category. And on both of these pages, the canonical link tag references a 3rd URL like www.example.com/skater-skirt-12345. This 3rd URL, used in the canonical link tag is a valid page, and displays the same content as the other two versions, but there are no actual links to this generic version anywhere on the site (nor external). Questions: 1. Does the generic URL referenced in the canonical link also need to be included as on-page links somewhere in the crawled navigation of the site, or is it okay to be just a valid URL not linked anywhere except for the canonical tags? 2. In our sitemap, is it okay to reference the non-canonical URLs, or does the sitemap have to reference only the canonical URL? In our case, the sitemap points to yet a 3rd variation of the URL, like www.example.com/product.jsp?productID=12345. This page retrieves the same content as the others, and includes a canonical link tag back to www.example.com/skater-skirt-12345. Is this a valid approach, or should we revise the sitemap to point to either the category-specific links or the canonical links?

Site Architecture: Cross Linking vs. Siloing
I'm curious to know what other mozzers think about silo's... Can we first all agree that a flat site architecture is the best practice? Relevant pages should be grouped together. Shorter, broader and (usually) therefore higher volume keywords should be towards the top of each category. Navigation should flow from general to specific. Agreed? As Google say's on page 10 of their SEO Starter Guide, "you should think about how visitors will go from a general page (your root page) to a page containing more specific content ." OK, we all agree so far, right? Great! Enter my question: Bruce Clay (among others) seem to recommend siloing as a best practice. While Richard Baxter (and many others @ SEOmoz), seem to view silos as a problem. Me? I've practiced (relevant) internal cross linking, and have intentionally avoided siloing in almost all cases. What about you? Is there a time and place to use silos? If so, when and where? If not, how do we rectify the seemingly huge differences of opinions between expert folks such as Baxter and Clay?

Sitemap in SERPS
What's up guys, Having some troubles with SERP rankings. My sitemap (navigation) is appearing instead of my actual keywords. I have tried a few methods to fix this; setting a preferred domain, using a 301 redirects, deleting out of date pages via Google webmaster tools. Nothing seems to work. My next step was to refresh the cache for my entire site - does anyone know how to do this? Can't see any tools... Any help would be great. Cheers, Jon.
