Crawl Issue Found: No rel="canonical" Tags
-
Given that google have stated that duplicate content is not penalised is this really something that will give sufficient benefits for the time involved?Also, reading some of the articles on moz.com they seem very ambivalent about its use – for example http://moz.com/blog/rel-confused-answers-to-your-rel-canonical-questionsWill any page with a canonical link normally NOT be indexed by google?Thanks.

Google has stated that duplicate content will be penalized, if it is deemed that the content is meant to manipulate search results. https://support.google.com/webmasters/answer/66359
"In the rare cases in which Google perceives that duplicate content may be shown with intent to manipulate our rankings and deceive our users, we'll also make appropriate adjustments in the indexing and ranking of the sites involved. As a result, the ranking of the site may suffer, or the site might be removed entirely from the Google index, in which case it will no longer appear in search results."
If two pages both have the same content, even with a canoical url Google will choose which one to index most likely the newer version of that page.
"Google tries hard to index and show pages with distinct information. This filtering means, for instance, that if your site has a "regular" and "printer" version of each article, and neither of these is blocked with a noindex meta tag, we'll choose one of them to list."I would not recommend having duplicate content on your site if it can be avoided. If it can't, set one of the pages you dont want indexed to "no-index".

Thanks. Should I add the canonical tag to all pages on the website? And how do I do this in WordPress SEO?

A canonical tag tells Google that you are aware of the duplicate content that exists on your website and you are telling Google which page to count as the authority. Pages with a canonical tag WILL be indexed.
Websites with duplicate content can, have and will be penalised by Google, that is what Panda is all about. The canonical tag does fix this in the majority of times but if there is a way of removing any duplicate content then this is advisable.

Complicated Title Tag Issues. Experts, Please Help!
Hey there Moz community! This is the first time I ask a question here so please forgive me if I miss any forum etiquette. I am managing SEO for an educational site which is built in React Js, and so far much of the job has been keyword research and site optimization. The site still has slow PageSpeed though. The Issues - 4 weeks ago we published 20 or so content pieces, I had pre-prepared title tags and meta descriptions. But when we released the content there was a programming error that made all of the pages show another title tag for all 20 pages instead of the pre-prepared individual title tags. I noticed this after 3 days and the issue was fixed within 6 days, but by then Google had crawled and indexed the pages. And now I can't get Google to change to the pre-prepared tags no matter what I do! I've tried changing the content, changing the URL of one of the pages, and I've sent Google spiders to re-crawl the pages multiple times. The super weird thing is that the correct title tag shows in the 'navigation bar/tabs bar' on google chrome:
Intermediate & Advanced SEO | | LeowaBut NOT when I view the source code for the page:
Yesterday I was taking a walk in the park and I just couldn't stop thinking about it (it is really starting to get to me by now since nothing works), so I ran back home and looked closely at one of these pages in the Google search console. And I noticed something I hadn't seen before… BOTH of the title tags can be found in the HTML: Pre-prepared title tag: <title></strong>UK Seat Belt & Car Seat Laws: The Definitive Guide<strong></title>
The other title tag (in src section): title=Ace%20The%20DMV%20Permit%20Test%20%26%20Get%20Your%20License
Could this be the problem or what do you think? I've understood that Google has automated title tags and that they can choose their own if they think it fits better, but the title tags aren't even close to describing the topic as it is now so it doesn’t make any sense. All answers are greatly appreciated! Your advice is life-saving for a learner like me. P.S. I love SEO but it can be very frustrating sometimes! Thank you very much, Leo

Importance (or lack of) Meta keywords tags and Tags in Drupal
I'm wondering should I put any effort in making Meta Keywords tags for my pages or normal Tags (they're separate in Drupal), since apparently first are not considered by most of search engines, while not sure about normal tags. Obviously SERPS has to determine partial valu of the page by content, thus consider keywords / tags to some extend. What's your opinion on that. Thank you.

Are there any downsides to using a canonical tag temporarily?
I'm working on redesigning our website. One of the content types has a main archive page (/success-stories) containing all of the success stories (written by graduates of our program). Because we plan to have success stories for other people (non-graduates), I'm using category hierarchies (/success-stories/graduates and success-stories/nonprofits, for example). It will go one level deeper to organize graduates by graduation year (/success-stories/graduates/%year%). I think this will work out well. However, we won't have non-graduate success stories for a little while, probably at least a few weeks, which means that /success-stories and /.../graduates indices will contain the same content for a while. So my question is this: Will it hurt to use a canonical tag that points to /success-stories/graduates as the authority until the main archive page contains more than just graduates? Or would it be better to use a 302 redirect from /success-stories to /.../graduates until more diverse content is added?

Having issues crawling a website
We looked to use the Screaming Frog Tool to crawl this website and get a list of all meta-titles from the site, however, it only resulted with the one result - the homepage. We then sought to obtain a list of the URLs of the site by creating a sitemap using https://www.xml-sitemaps.com/. Once again however, we just go the one result - the homepage. There is something that seems to be restricting these tools from crawling all pages. If you anyone can shed some light as to what this could be, we'd be most appreciative.

Crawl diagnostic issue?
I'am sorry if my English isn't very good, but this is my problem at the moment: On two of my campagnes I get a weird error on Moz Analytics: 605 Page Banned by robots.txt, X-Robots-Tag HTTP Header, or Meta Robots Tag Moz Analytics points to an url that starts with: http:/**/None/**www.????.com. We don't understand how Moz indexed this non-existing page that starts with None? And how can we solve this error? I hope that someone can help me.

Show wordpress "archive links" on blog?
I here conflicting reports on whether to show wordpress archive links on the blog or not. Some say it is important for viewers to see, others say it is not and creates way too many links. I think both have good points but for SEO purposes, I lean towards removing them. What do Moz users think?

How Rel=Prev & Rel=Next work for me?
I have implemented Rel=Prev & Rel=Next tag on my website. I would like to give example URL to know more about it. http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=3 http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=4 http://www.vistapatioumbrellas.com/market-umbrellas?limit=40&p=5 Right now, I have blocked paginated pages by Robots.txt by following query. Disallow: /*?p= I have removed disallow syntax from Robots.txt for paginated pages. But, I have confusion with duplicate page title. If you will check all 3 pages so you will find out duplicate page title across all pages. I know that, duplicate page title is harmful for SEO. Will Google crawl + index all paginated pages? If yes so which page will get maximum benefits in organic ranking? Is there any specific way which may help me to solve this issue?

Proper use and coding of rel = "canonical" tag
I'm working on a site that has pages for many wedding vendors. There are essentially 3 variations of the page for each vendor with only slightly different content, so they're showing up as "duplicate content" in my SEOmoz Campaign. Here's an example of the 3 variations: http://www.weddingreportsma.com/MA-wedding.cfm/vendorID/4161 http://www.weddingreportsma.com/MA-wedding.cfm?vendorID=4161&action=messageWrite http://www.weddingreportsma.com/MA-wedding.cfm?vendorID=4161&action=writeReview Because of this, we placed a rel="canoncial" tag in the second 2 pages to try to fix the problem. However, the coding does not seem to validate in the w3 html validator. I can't say I understand html well enough to understand the error the validator is pointing out. We also added a the following to the second 2 types of pages <meta name="robots" content="noindex"> Am I employing this tag correctly in this case? Here is a snippet of the code below. <html> <head> <title>Reviews on Astonishing Event, Inc from Somerset MAtitle> <link rel="stylesheet" type="text/css" href="[/includes/style.css](view-source:http://www.weddingreportsma.com/includes/style.css)"> <link href="[http://www.weddingreportsma.com/MA-wedding.cfm/vendorID/4161](view-source:http://www.weddingreportsma.com/MA-wedding.cfm/vendorID/4161)" rel="canonical" /> <meta name="robots" content="noindex">
