Do URLs with canonical tags get indexed by Google?
-
Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop.
Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

Thanks so much! Really helpful!

Not exactly. Its not so much that the canonical "supersedes" an index, follow tag.... a canonical tag establishes equivalency while a NoIndex is more like a "does not equal." The Index, Follow is still there and being seen by bots as they crawl... in fact, if you had NoIndex on a page with a Canonical Tag, it may not even see the canonical at all since you told it to NoIndex the page. The Meta Robots Index tag comes first allowing the bots to crawl and index the page but then the canonical sets up equivalency to a separate page. So if your canonical tag is being respected, it doesn't wind up doing the same thing as a NoIndex (though it may seem that way) nor does it do the same thing as a 301 (though there are similarities in how equity is passed). Since a canonical establishes an equivalency, you'll find that the Canon Page will eventually take the place of the Canonicalized Page in search results because you're telling them the Canonicalized Page _is _the Canon Page & that the Canon page is the right version of both.

Thanks, Mike! So, just to clarify, for a particular URL, if we have Meta Robots set to "Index/Follow" and that same URL has a canonical tag, the canonical tag would supersede the robot command and the URL would not be indexed?

If a URL was indexed and has since had a canonical added to it pointing to another page, it will eventually disappear from results. Basically the pages gets consolidated with its canon page. If the bots choose to respect the canonical tag in that instance, all signals get passed to the canon page while still allowing the page and information to be accessible by human visitors. As such, there's no reason to keep the page in the index because you're telling the bots that another page is the correct page instead. This is not the same as NoIndexing a page but will eventually remove a page from the index much in the same way that a 301 will pass equity along to another page while eventually removing the redirected page from the index in favor of the page being redirected to.

Google Not Indexing Pages (Wordpress)
Hello, recently I started noticing that google is not indexing our new pages or our new blog posts. We are simply getting a "Discovered - Currently Not Indexed" message on all new pages. When I click "Request Indexing" is takes a few days, but eventually it does get indexed and is on Google. This is very strange, as our website has been around since the late 90's and the quality of the new content is neither duplicate nor "low quality". We started noticing this happening around February. We also do not have many pages - maybe 500 maximum? I have looked at all the obvious answers (allowing for indexing, etc.), but just can't seem to pinpoint a reason why. Has anyone had this happen recently? It is getting very annoying having to manually go in and request indexing for every page and makes me think there may be some underlying issues with the website that should be fixed.

Help with Getting Googlebot to See Google Charts
We received a message from Google saying we have an extremely high number of URLs that are linking to pages with similar or duplicate content. The main difference between these pages are the Google charts we use. It looks like Google isn't able to see these charts (most of the text are very similar) and the charts (lots of it) are the main differences between these pages. So my question is what is the best approach to allowing Google to see the data that exists in these charts? I read from here http://webmasters.stackexchange.com/questions/69818/how-can-i-get-google-to-index-content-that-is-written-into-the-page-with-javascr that a solution would be to have the text that is displayed on the charts coded into the html and hidden by CSS. I'm not sure but it seems like a bad idea to have it seen by Google but hidden to the user by CSS. It just sounds like a cloaking hack. Can someone clarify if this is even a solution or is there a better solution?

Google changing title tags to branded
Hi guys and gals, i noticed in the results today Google has been changing my title tags so that brand: is in the front of it all. This is not in the code but my title tag structure site-wide is keywords and then always | brand on the end. Why has this happened does anyone know? does it affect my first keyword in the title tag, i guess Google might do it as it recognises the brand and wants users to know it?

Why Google did not index our domain?
Hi, We launched tmart 60 days ago and submitted to google, bing, yahoo 20 days later. But google had never indexed our website still when yahoo indexed it in one week. What we have checked or tried: 1. We got 20~50 inlinks in one month and now 81 inlinks via yahoo site explorer. 2. This domain has registered for 13 years and we purchased it from sedo last year. We

did not find any problems from domain archive pages. 3. Page similar: the homepage is 50% similar to one of our competitors when we just launched.
So we adjusted the page structure and modified the content one month later and decreased the similarity to 30% (by tools from webconfs.com) 4. Google Robots: googlebot crawled our website every day after we submitted for indexing.
We opened GWT account for it and added the xml sitemap last week. GWT said nothing
was wrong except the time of page loading. Our questions: Why google did not indexed our website? What should we do? Thanks, wu0
