Sitemap use for very large forum-based community site
-
I work on a very large site with two main types of content, static landing pages for products, and a forum & blogs (user created) under each product. Site has maybe 500k - 1 million pages. We do not have a sitemap at this time.
Currently our SEO discoverability in general is good, Google is indexing new forum threads within 1-5 days roughly. Some of the "static" landing pages for our smaller, less visited products however do not have great SEO.
Question is, could our SEO be improved by creating a sitemap, and if so, how could it be implemented? I see a few ways to go about it:- Sitemap includes "static" product category landing pages only - i.e., the product home pages, the forum landing pages, and blog list pages. This would probably end up being 100-200 URLs.
- Sitemap contains the above but is also dynamically updated with new threads & blog posts.
Option 2 seems like it would mean the sitemap is unmanageably long (hundreds of thousands of forum URLs). Would a crawler even parse something that size? Or with Option 1, could it cause our organically ranked pages to change ranking due to Google re-prioritizing the pages within the sitemap?
Not a lot of information out there on this topic, appreciate any input. Thanks in advance. -
Agreed, you'll likely want to go with option #2. Dynamic sitemaps are a must when you're dealing with large sites like this. We advise them on all of our clients with larger sites. If your forum content is important for search then these are definitely important to include as the content likely changes often and might be naturally deeper in the architecture.
In general, I'd think of sitemaps from a discoverability perspective instead of a ranking one. The primary goal is to give Googlebot an avenue to crawl your sites content regardless of internal linking structure.

Hi
Go with option 2, there is no scaling issue here. I have worked with and for sites that have a high multiplier on the number of sitemaps and pages that they're submitting, in some cases up to 100M pages. In all cases, Google was totally fine in crawling and processing the data that was there. As long as you follow the guidelines (max 50K URLs in a sitemap) you're fine as you're just providing another file that usually doesn't exceed about 50MB (depending on if you also add images to the sitemap). If you have an engineering team build the right infrastructure you can easily deal with thousands of these files and run them automated every day/week.
My main focus on big sites is also to streamline their sitemaps to have sitemaps with just the last 50.000 pages and the same for the last 50.000 pages that were updated. This way you're able to also monitor the indexation level of these pages. If you are able to, for example, combine the data from log file analysis you can say: we added 50K pages and Google in the last days were able to crawl X percentage of that.
Hope this gives you some extra insights.
Martijn.

If I'm using a compressed sitemap (sitemap.xml.gz) that's the URL that gets submitted to webmaster tools, correct?
I just want to verify that if a compressed sitemap file is being used, then the URL that gets submitted to Google, Bing, etc and the URL that's used in the robots.txt indicates that it's a compressed file. For example, "sitemap.xml.gz" -- thanks!

Desktop & Mobile XML Sitemap Submitted But Only Desktop Sitemap Indexed On Google Search Console
Hi! The Problem We have submitted to GSC a sitemap index. Within that index there are 4 XML Sitemaps. Including one for the desktop site and one for the mobile site. The desktop sitemap has 3300 URLs, of which Google has indexed (according to GSC) 3,000 (approx). The mobile sitemap has 1,000 URLs of which Google has indexed 74 of them. The pages are crawlable, the site structure is logical. And performing a Landing Page URL search (showing only Google/Organic source/medium) on Google Analytics I can see that hundreds of those mobile URLs are being landed on. A search on mobile for a longtail keyword from a (randomly selected) page shows a result in the SERPs for the mobile page that judging by GSC has not been indexed. Could this be because we have recently added rel=alternate tags on our desktop pages (and of course corresponding canonical ones on mobile). Would Google then 'not index' rel=alternate page versions? Thanks for any input on this one. PmHmG

Canonical homepage link uses trailing slash while default homepage uses no trailing slash, will this be an issue?
Hello, 1st off, let me explain my client in this case uses BigCommerce, and I don't have access to the backend like most other situations. So I have to rely on BG to handle certain issues. I'm curious if there is much of a difference using domain.com/ as the canonical url while BG currently is redirecting our domain to domain.com. I've been using domain.com/ consistently for the last 6 months, and since we switches stores on Friday, this issue has popped up and has me a bit worried that we'll loose somehow via link juice or overall indexing since this could confuse crawlers. Now some say that the domain url is fine using / or not, as per - https://moz.com/community/q/trailing-slash-and-rel-canonical But I also wanted to see what you all felt about this. What says you?

Should I include tags in sitemap?
Hello All, I was wondering if you should include tags and categories in your sitemap. In the past on previous blogs I have always left tags and categories out. The reason for this is a good friend of mine who has been doing SEO for a long time and inhouse always told me that this would result in duplicate content. I thought that it would be a great idea to get some input from the SEOmoz community as this obviously has a big affect on your blog and the number of pages indexed. Any help would be great. Thanks, Luke Hutchinson.

Index forum sites
Hi Moz Team, somehow the last question i raised a few days ago not only wasnt answered up until now, it was also completely deleted and the credit was not "refunded" - obviously there was some data loss involved with your restructuring. Can you check whether you still find the last question and answer it quickly? I need the answer 🙂 Here is one more question: I bought a website that has a huge forum, loads of pages with user generated content. Overall around 500.000 Threads with 9 Million comments. The complete forum is noindex/nofollow when i bought the site, now i am thinking about what is the best way to unleash the potential. The current system is vBulletin 3.6.10. a) Shall i first do an update of vbulletin to version 4 and use the vSEO tool to make the URLs clean, more user and search engine friendly before i switch to index/follow? b) would you recommend to have the forum in the folder structure or on a subdomain? As far as i know subdomain does take lesser strenght from the TLD, however, it is safer because the subdomain is seen as a separate entity from the regular TLD. Having it in he folder makes it easiert to pass strenght from the TLD to the forum, however, it puts my TLD at risk c) Would you release all forum sites at once or section by section? I think section by section looks rather unnatural not only to search engines but also to users, however, i am afraid of blasting more than a millionpages into the index at once. d) Would you index the first page of a threat or all pages of a threat? I fear duplicate content as the different pages of the threat contain different body content but the same Title and possibly the same h1. Looking forward to hear from you soon! Best Fabian
