Removing massive number of no index follow page that are not crawled
-
Hi,
We have stackable filters on some of our pages (ie: ?filter1=a&filter2=b&etc.). Those stacked filters pages are "noindex, follow". They were created in order to facilitate the indexation of the item listed in them.
After analysing the logs we know that the search engines do not crawl those stacked filter pages.
Does blocking those pages (by loading their link in AJAX for example) would help our crawl rate or not? In order words does removing links that are already not crawled help the crawl rate of the rest of our pages?
My assumption here is that SE see those links but discard them because those pages are too deep in our architecture and by removing them we would help SE focus on the rest of our page. We don't want to waste our efforts removing those links if there will be no impact.
Thanks

Personally I don't agree with setting internal filter URLs to nofollow. I set noindex as you have done and add the filter attributes to the Search Console > Crawl > URL Parameters.
For the option "Which URLs with this parameter should Googlebot crawl?" you can set "No URLs" (if the filters are uniform throughout the site).
"No URLs: Googlebot won't crawl any URLs containing this parameter. This is useful if your site uses many parameters to filter content. For example, telling Googlebot not to crawl URLs with less significant parameters such as
pricefrom
andpriceto
(likehttp://www.examples.com/search?category=shoe&brand=nike&color=red&size=5&pricefrom=10&priceto=1000
) can prevent the unnecessary crawling of content already available from a page without those parameters (likehttp://www.examples.com/search?category=shoe&brand=nike&color=red&size=5)"

noindex means that crawlers can still visit the page (using crawl budget). You would need to link to those pages using a nofollow tag + block via robots.txt to prevent crawlers from accessing them.
Overall, if those pages aren't being crawled currently, then they aren't affecting your crawl budget since they aren't being visited. However, if you build more authority to your website, your crawl budget will grow so crawlers might start visiting those pages again.

Best Practice Approaches to Canonicals vs. Indexing in Google Sitemap vs. No Follow Tags
Hi There, I am working on the following website: https://wave.com.au/ I have become aware that there are different pages that are competing for the same keywords. For example, I just started to update a core, category page - Anaesthetics (https://wave.com.au/job-specialties/anaesthetics/) to focus mainly around the keywords ‘Anaesthetist Jobs’. But I have recognized that there are ongoing landing pages that contain pretty similar content: https://wave.com.au/anaesthetists/ https://wave.com.au/asa/ We want to direct organic traffic to our core pages e.g. (https://wave.com.au/job-specialties/anaesthetics/). This then leads me to have to deal with the duplicate pages with either a canonical link (content manageable) or maybe alternatively adding a no-follow tag or updating the robots.txt. Our resident developer also suggested that it might be good to use Google Index in the sitemap to tell Google that these are of less value? What is the best approach? Should I add a canonical link to the landing pages pointing it to the category page? Or alternatively, should I use the Google Index? Or even another approach? Any advice would be greatly appreciated. Thanks!

Can noindexed pages accrue page authority?
My company's site has a large set of pages (tens of thousands) that have very thin or no content. They typically target a single low-competition keyword (and typically rank very well), but the pages have a very high bounce rate and are definitely hurting our domain's overall rankings via Panda (quality ranking). I'm planning on recommending we noindexed these pages temporarily, and reindex each page as resources are able to fill in content. My question is whether an individual page will be able to accrue any page authority for that target term while noindexed. We DO want to rank for all those terms, just not until we have the content to back it up. However, we're in a pretty competitive space up against domains that have been around a lot longer and have higher domain authorities. Like I said, these pages rank well right now, even with thin content. The worry is if we noindex them while we slowly build out content, will our competitors get the edge on those terms (with their subpar but continually available content)? Do you think Google will give us any credit for having had the page all along, just not always indexed?

Removing Parameterized URLs from Google Index
We have duplicate eCommerce websites, and we are in the process of implementing cross-domain canonicals. (We can't 301 - both sites are major brands). So far, this is working well - rankings are improving dramatically in most cases. However, what we are seeing in some cases is that Google has indexed a parameterized page for the site being canonicaled (this is the site that is getting the canonical tag - the "from" page). When this happens, both sites are being ranked, and the parameterized page appears to be blocking the canonical. The question is, how do I remove canonicaled pages from Google's index? If Google doesn't crawl the page in question, it never sees the canonical tag, and we still have duplicate content. Example: A. www.domain2.com/productname.cfm%3FclickSource%3DXSELL_PR is ranked at #35, and B. www.domain1.com/productname.cfm is ranked at #12. (yes, I know that upper case is bad. We fixed that too.) Page A has the canonical tag, but page B's rank didn't improve. I know that there are no guarantees that it will improve, but I am seeing a pattern. Page A appears to be preventing Google from passing link juice via canonical. If Google doesn't crawl Page A, it can't see the rel=canonical tag. We likely have thousands of pages like this. Any ideas? Does it make sense to block the "clicksource" parameter in GWT? That kind of scares me.

Google de-indexed a page on my site
I have a site which is around 9 months old. For most search terms we rank fine (including top 3 rankings for competitive terms). Recently one of our pages has been fluctuating wildly in the rankings and has now disappeared altogether from the rankings for over 1 week. As a test I added a similar page to one of my other sites and it ranks fine. I've checked webmaster tools and there is nothing of note there. I'm not really sure what to do at this stage. Any advice would me much appreciated!

Links from non-indexed pages
Whilst looking for link opportunities, I have noticed that the website has a few profiles from suppliers or accredited organisations. However, a search form is required to access these pages and when I type cache:"webpage.com" the page is showing up as non-indexed. These are good websites, not spammy directory sites, but is it worth trying to get Google to index the pages? If so, what is the best method to use?

Our login pages are being indexed by Google - How do you remove them?
Each of our login pages show up under different subdomains of our website. Currently these are accessible by Google which is a huge competitive advantage for our competitors looking for our client list. We've done a few things to try to rectify the problem: - No index/archive to each login page Robot.txt to all subdomains to block search engines gone into webmaster tools and added the subdomain of one of our bigger clients then requested to remove it from Google (This would be great to do for every subdomain but we have a LOT of clients and it would require tons of backend work to make this happen.) Other than the last option, is there something we can do that will remove subdomains from being viewed from search engines? We know the robots.txt are working since the message on search results say: "A description for this result is not available because of this site's robots.txt – learn more." But we'd like the whole link to disappear.. Any suggestions?

Getting 260,000 pages re-indexed?
Hey there guys, I was recently hired to do SEO for a big forum to move the site to a new domain and to get them back up to their ranks after this move. This all went quite well, except for the fact that we lost about 1/3rd of our traffic. Although I expected some traffic to drop, this is quite a lot and I'm wondering what it is. The big keywords are still pulling the same traffic but I feel that a lot of the small threads on the forums have been de-indexed. Now, with a site with 260,000 threads, do I just take my loss and focus on new keywords? Or is there something I can do to get all these threads re-indexed? Thanks!
