XML Sitemap Index Percentage (Large Sites)
-
Hi all
I'm wanting to find out from those who have experience dealing with large sites (10s/100s of millions of pages).
What's a typical (or highest) percentage of indexed pages vs. submitted pages you've seen? This information can be found in webmaster tools where Google shows you the pages submitted & indexed for each of your sitemap.
I'm trying to figure out whether,
- The average index % out there
- There is a ceiling (i.e. will never reach 100%)
- It's possible to improve the indexing percentage further
Just to give you some background, sitemap index files (according to schema.org) have been implemented to improve crawl efficiency and I'm wanting to find out other ways to improve this further.
I've been thinking about looking at the URL parameters to exclude as there are hundreds (e-commerce site) to help Google improve crawl efficiency and utilise the daily crawl quote more effectively to discover pages that have not been discovered yet.
However, I'm not sure yet whether this is the best path to take or I'm just flogging a dead horse if there is such a ceiling or if I'm already at the average ballpark for large sites.
Any suggestions/insights would be appreciated. Thanks.

I've worked on a site that was ~100 million pages, and I've seen indexation percentages ranging from 8% to 95%. When dealing with sites this size, there are so, so many issues at play, and there are so few sites of this size that finding an average probably won't do you much good.
Rather than focusing on whether or not you have enough pages indexed based on averages, you should focus on two key questions: "do my sitemaps only include pages that would make great search engine entry pages" and "have I done everything possible to eliminate junk pages that are wasting crawl bandwidth."
Of course, making sure you don't have any duplicate content, thin content, or poor on-site optimization issues should also be a focus.
I guess what I'm trying to say is, I believe any site can have 100% of it's search entry worthy pages indexed, but sites of that size rarely have ALL of their pages indexed since sites that large often have a ton of pages that don't make great search results.

XML sitemap generator only crawling 20% of my site
Hi guys, I am trying to submit the most recent XML sitemap but the sitemap generator tools are only crawling about 20% of my site. The site carries around 150 pages and only 37 show up on tools like xml-sitemaps.com. My goal is to get all the important URLs we care about into the XML sitemap. How should I go about this? Thanks

Google Is Indexing my 301 Redirects to Other sites
Long story but now i have a few links from my site 301 redirecting to youtube videos or eCommerce stores. They carry a considerable amount of traffic that i benefit from so i can't take them down, and that traffic is people from other websites, so basically i have backlinks from places that i don't own, to my redirect urls (Ex. http://example.com/redirect) My problem is that google is indexing them and doesn't let them go, i have tried blocking that url from robots.txt but google is still indexing it uncrawled, i have also tried allowing google to crawl it and adding noindex from robots.txt, i have tried removing it from GWT but it pops back again after a few days. Any ideas? Thanks!

This url is not allowed for a Sitemap at this location error using pro-sitemaps.com
Hey, guys, We are using the pro-sitemaps.com tool to automate our sitemaps on our properties, but some of them give this error "This url is not allowed for a Sitemap at this location" for all the urls. Strange thing is that not all of them are with the error and most have all the urls indexed already. Do you have any experience with the tool and what is your opinion? Thanks

Does anyone know of any tools that can help split up xml sitemap to make it more efficient and better for seo?
Hello All, We want to split up our Sitemap , currently it's almost 10K pages in one xml sitemap but we want to make it in smaller chunks splitting it by category or location or both. Ideally into 100 per sitemap is what I read is the best number to help improve indexation and seo ranking. Any thoughts on this ? Does anyone know or any good tools out there which can assist us in doing this ? Also another question I have is that should we put all of our products (1250) in one site map or should this also be split up in to say products for category etc etc ? thanks Pete

Where is the best place to put a sitemap for a site with local content?
I have a simple site that has cities as subdirectories (so URL is root/cityname). All of my content is localized for the city. My "root" page simply links to other cities. I very specifically want to rank for "topic" pages for each city and I'm trying to figure out where to put the sitemap so Google crawls everything most efficiently. I'm debating the following options, which one is better? Put the sitemap on the footer of "root" and link to all popular pages across cities. The advantage here is obviously that the links are one less click away from root. Put the sitemap on the footer of "city root" (e.g. root/cityname) and include all topics for that city. This is how Yelp does it. The advantage here is that the content is "localized" but the disadvantage is it's further away from the root. Put the sitemap on the footer of "city root" and include all topics across all cities. That way wherever Google comes into the site they'll be close to all topics I want to rank for. Thoughts? Thanks!

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

How do you de-index and prevent indexation of a whole domain?
I have parts of an online portal displaying in SERPs which it definitely shouldn't be. It's due to thoughtless developers but I need to have the whole portal's domain de-indexed and prevented from future indexing. I'm not too tech savvy but how is this achieved? No index? Robots? thanks

Best possible linking on site with 100K indexed pages
Hello All, First of all I would like to thank everybody here for sharing such great knowledge with such amazing and heartfelt passion.It really is good to see. Thank you. My story / question: I recently sold a site with more than 100k pages indexed in Google. I was allowed to keep links on the site.These links being actual anchor text links on both the home page as well on the 100k news articles. On top of that, my site syndicates its rss feed (Just links and titles, no content) to this page. However, the new owner made a mess, and now the site could possibly be seen as bad linking to my site. Google tells me within webmasters that this particular site gives me more than 400K backlinks. I have NEVER received one single notice from Google that I have bad links. That first. But, I was worried that this page could have been the reason why MY site tanked as bad as it did. It's the only source linking so massive to me. Just a few days ago, I got in contact with the new site owner. And he has taken my offer to help him 'better' his site. Although getting the site up to date for him is my main purpose, since I am there, I will also put effort in to optimizing the links back to my site. My question: What would be the best to do for my 'most SEO gain' out of this? The site is a news paper type of site, catering for news within the exact niche my site is trying to rank. Difference being, his is a news site, mine is not. It is commercial. Once I fix his site, there will be regular news updates all within the niche we both are in. Regularly as in several times per day. It's news. In the niche. Should I leave my rss feed in the side bars of all the content? Should I leave an achor text link on the sidebar (on all news etc.) If so: there can be just one keyword... 407K pages linking with just 1 kw?? Should I keep it to just one link on the home page? I would love to hear what you guys think. (My domain is from 2001. Like a quality wine. However, still tanked like a submarine.) ALL SEO reports I got here are now Grade A. The site is finally fully optimized. Truly nice to have that confirmation. Now I hope someone will be able to tell me what is best to do, in order to get the most SEO gain out of this for my site. Thank you.
