Canonical issues using Screaming Frog and other tools?
-
In the Directives tab within Screaming Frog, can anyone tell me what the difference between "canonicalised", "canonical", and "no canonical" means? They're found in the filter box. I see the data but am not sure how to interpret them. Which one of these would I check to find canonical issues within a website? Are there any other easy ways to identify canonical issues?

Hello
I spotted this thread and was just about to reply, but Dirk has answered it all perfectly. Thanks Dirk!
Under 'reports' there's also a 'canonical errors' report which will show canonicals with various technical issues - Those that are blocked by robots.txt, have no response, 3XX redirect, 4XX or 5XX error (essentially anything other than a 200 ‘OK’ response). It will also show any URLs discovered only via a canonical, that are not linked to internally from the sites own link structure (in the ‘unlinked’ column when ‘true’).
Hope that helps anyway.
Cheers!

Hi,
The difference between them
-
canonical : url has a canonical url - which can be self-referencing (canonical url = url) or not
-
canonicalised: url has a canonical url which is not self-referencing (canonical url <> url)
-
no canonical : quite obvious - the url has no canonical.
Potential issues could be - url's that you would like to have a canonical don't have a canonical or url's that are canonicalised don't have the right canonical url. You can use the lists (both canonicalised & no canonical) from Screaming Frog to check them - but it's up to you to judge whether the canonical is ok or not (no automated tool can guess what your intentions are).
Typical mistakes with canonicals: all url's have the same canonical url (like the homepage), or have canonical url's that do not exist. You could also check this with Screaming Frog using the setting "respect canonicals" - this way only the canonical url's will be shown in the listing.Also keep in mind that canonical url's are merely a friendly request to Google to index the canonical rather than the normal url - but it's not an obligation for Google to do this (check https://support.google.com/webmasters/answer/139066?hl=en quote: "the search results will be more likely to show users that URL structure. (Note: We attempt to respect this, but cannot guarantee this in all cases.)"

Should we use Cloudflare
Hi all, we want to speed up our website (hosted in Wordpress, traffic around 450,000 page views monthly), we use lots of images. And we're wondering about setting up on Cloudflare, however after searching a bit in Google I have seen some people say the change in IP, or possible sharing of Its with bad neighbourhoods, can really hit search rankings. So, I was wondering what the latest thinking is on this subject, would the increased speed and local server locations be a boost for SEO, moreso than a potential loss of rankings for changing IP? Thanks!

Redirect and ranking issue
Hi there - was wondering whether someone might be able to help. For a period of a day and a half, all the traffic to our website's blog articles were mistakenly being redirected to our homepage. A number of these articles ranked in the top 5 in Google worldwide for their targeted keywords, so this was a considerable amount of organic traffic that was instantly being redirected. It was a strange site glitch and our web team rectified the error, but now all these articles have disappeared from Google rankings (not visible anywhere in the first five pages). I'm presuming this must be linked to this redirect issue - we've been advised to wait and see whether Google restores these rankings, but I'm still concerned as to whether this represents a more serious problem? We have re-indexed the pages we are most concerned about, but am not sure whether there is anything else obvious we should think to do. If anyone has any thoughts, I'd be happy to hear them!

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!

Google serp pagination issue
We are a local real estate company and have landing pages for different communities and cities around our area that display the most recent listings. For example: www.mysite.com/wa/tumwater is our landing page for the city of Tumwater homes for sale. Google has indexed most of our landing pages, but for whatever reason they are displaying either page 2, 3, 4 etc... instead of page 1. Our Roy, WA landing page is another example. www.mysite.com/wa/roy has recently been showing up on page 1 of Google for "Roy WA homes for sale", but now we are much further down and www.mysite.com/wa/roy?start=80 (page 5) is the only page in the serps. (coincidentally we no longer have 5 pages worth of listings for this city, so this link now redirects to www.mysite.com/wa/roy.) We haven't made any major recent changes to the site. Any help would be much appreciated! *You can see what my site is in the attached image... I just don't want this post to show up when someone google's the actual name of the business 🙂 nTTrSMx.jpg C4mhfgh.jpg

PageSpeed Insights DNS Issue
Hi Anyone else having problems with Google's Pagespeed tool? I am trying to benchmark a couple of my sites but, according to Google, my sites are not loading. They will work when I run them through the test at one point but if I try again, say 15 mins later, they will present the following error message An error has occured DNS error while resolving DOMAIN. Check the spelling of the host, and ensure that the page is accessible from the public Internet. You may refresh to try again. If the problem persists, please visit the PageSpeed Insights mailing list for support. This isn't too much an issue for testing page speed but am concerned that if Google is getting this error on the speed test it will also get the error when trying to crawl and index the pages. I can confirm the sites are up and running. I the sites are pointed at the server via A-records and haven't been changed for many weeks so cannot be a dns updating issue. Am at a loss to explain. Any advice would be most welcome. Thanks.

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?

Does using parentheses affect the crawlers?
Quick question: if you using a parantheses around a keyword, do search bots still recognize the keyword? Fox ex: Welcome to a website about the National Basketball Association (NBA). Will the bots recognize that I'm trying to optimize to NBA and not (NBA)? Is this different for tags vs. actual body copy?
