Over 1000 pages de-indexed over night
-
Hello,
On my site (www.bridgman.co.uk) we had a lot of duplicate page issues as reported by the Seomoz site report tool - this was due to database driven URL strings. As a result, I sent an excel file with all the duplicate pages to my web developer who put rel canonical tags on what I assumed would be all the correct pages.
I am not sure if this is a coincidence, or a direct result of the canonical tags, but a few days after (yesterday) the amount of pages indexed by google dropped from 1,200 to under 200.
The number is still declining, and other than the canonical tags I can't work out why Google would just start de-indexing most of our pages.
If you could offer any solutions that would be greatly appreciated.
Thanks, Robert.

Canonical and duplicate content are both interresting issues, thanks for your anserws!
-
The 1st question I would ask myself as a website owner is: How many pages have duplicate content on them? Maybe try going the manual way and check for yourself. There will be pages you do not know about. Use a tool like Xenu's link sleuth to extract all links on your website(which are reachable from atleast 1 link of your website).
It may happen that google is adjusting its index for all. Worth keeping a track on whether your competitors are losing at the same or slower rate or not.
-
I would first remove the canonicals (or actually do them correctly) and wait for a re-crawl of the pages. If not, then re-submit.
Also, problems with canonicals do show up in the page grader app, so when your admin re-writes the canonical, test the page before Google sees it : )
-
It appears so
I've asked my webmaster to remove all of the canonical tags but after reading that article I feel that a lot of the damage has already been done!
Looks like I'll have to submit a reconsideration request and beg Google for forgiveness.
-
Hmm, I'd remove them.
The fact that all your individual product pages have a rel=canonical of productsdetail.asp and category level is products.asp is telling Google that all your products pages are the same!
The problem is there are a lot of parameters in your URLs, let me go have a look at how to deal with that when using the canonical tag.
EDIT - Spent half my lunch on this but couldn't find much
I would guess you can get away with parameters in the canonical tag so decide which is the official URL and put that in the header for that paticular piece of content. Only really found this - http://googlewebmastercentral.blogspot.com/2009/02/specify-your-canonical.html -
Could you be in a canonical loop?
-
I don't think this is a result of an algo change, I've just had a look at the crawl diagnostics and it appears that he has put the tag value of the homepage (www.bridgman.co.uk/ - where all the back links are pointed to) as www.bridgman.co.uk/default.asp !!
This has also been done to all of our product pages!! i.e.all of the duplicated product pages now have the tag value - www.bridgman.co.uk/productdetail.asp (a page which doesn't even exist on our site!!!)
Now I may be stating the obvious, but I guess this is the problem?
He did this 8 days ago, where should I go from here? Ask him to remove all rel canonical tags and pray we bounce back....?
-
First question would be do you think this may have had an effect on you? - http://searchengineland.com/google-forecloses-on-content-farms-with-farmer-algorithm-update-66071
All your content unique? Your links come from sites that may have been effected?
If not then I'd give it a few days to see if they come back (as HR128 says, may just be Google working out what's changed and what to do) and I'm doing a quick crawl of your site to see what I can see
-
It could take a couple of days before you see results, Google has to step back and reassess most likely, or your web developer has no clue what he's doin haha.

404 Errors for Form Generated Pages - No index, no follow or 301 redirect
Hi there I wonder if someone can help me out and provide the best solution for a problem with form generated pages. I have blocked the search results pages from being indexed by using the 'no index' tag, and I wondered if I should take this approach for the following pages. I have seen a huge increase in 404 errors since the new site structure and forms being filled in. This is because every time a form is filled in, this generates a new page, which only Google Search Console is reporting as a 404. Whilst some 404's can be explained and resolved, I wondered what is best to prevent Google from crawling these pages, like this: mydomain.com/webapp/wcs/stores/servlet/TopCategoriesDisplay?langId=-1&storeId=90&catalogId=1008&homePage=Y Implement 301 redirect using rules, which will mean that all these pages will redirect to the homepage. Whilst in theory this will protect any linked to pages, it does not resolve this issue of why GSC is recording as 404's in the first place. Also could come across to Google as 100,000+ redirected links, which might look spammy. Place No index tag on these pages too, so they will not get picked up, in the same way the search result pages are not being indexed. Block in robots - this will prevent any 'result' pages being crawled, which will improve the crawl time currently being taken up. However, I'm not entirely sure if the block will be possible? I would need to block anything after the domain/webapp/wcs/stores/servlet/TopCategoriesDisplay?. Hopefully this is possible? The no index tag will take time to set up, as needs to be scheduled in with development team, but the robots.txt will be an quicker fix as this can be done in GSC. I really appreciate any feedback on this one. Many thanks

How do I get my pages to go from "Submitted" to "Indexed" in Google Webmaster Tools?
Background: I recently launched a new site and it's performing much better than the old site in terms of bounce rate, page view, pages per session, session duration, and conversions. As suspected, sessions, users, and % new sessions are all down. Which I'm okay with because the the old site had a lot of low quality traffic going to it. The traffic we have now is much more engaged and targeted. Lastly, the site was built using Squarespace and was launched the middle of August. **Question: **When reviewing Google Webmaster Tools' Sitemaps section, I noticed it says 57 web pages Submitted, but only 5 Indexed! The sitemap that's submitted seems to be all there. I'm not sure if this is a Squarespace thing or what. Anyone have any ideas? Thanks!!

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

Pages removed from Google index?
Hi All, I had around 2,300 pages in the google index until a week ago. The index removed a load and left me with 152 submitted, 152 indexed? I have just re-submitted my sitemap and will wait to see what happens. Any idea why it has done this? I have seen a drop in my rankings since. Thanks

Translating Page Titles & Page Descriptions
I am working on a site that will be published in the original English, with localized versions in French, Spanish, Japanese and Chinese. All the versions will use the English information architecture. As part of the process, we will be translating the page the titles and page descriptions. Translation quality will be outstanding. The client is a translation company. Each version will get at least four pairs of eyes including expert translators, editors, QA experts and proofreaders. My question is what special SEO instructions should be issued to translators re: the page titles and page descriptions. (We have to presume the translators know nothing about SEO.) I was thinking of: stick to the character counts for titles and descriptions make sure the title and description work together avoid over repetition of keywords page titles (over-optimization peril) think of the descriptions as marketing copy try to repeat some title phrases in the description (to get the bolding and promote click though) That's the micro stuff. The macro stuff: We haven't done extensive keyword research for the other languages. Most of the clients are in the US. The other language versions are more a demo of translation ability than looking for clients elsewhere. Are we missing something big here?

Will Google Continue to Index the Page with NoIndex Tag Upon Google +1 Button Impression or Click?
The FAQs for Google +1 button suggests as follows: "+1 is a public action, so you should add the button only to public, crawlable pages on your site. Once you add the button, Google may crawl or recrawl the page, and store the page title and other content, in response to a +1 button impression or click." If my page has NoIndex tag, while at the same time inserted with Google +1 button on the page, will Google recognise the NoIndex Tag on the page (and will not index the page) despite the +1 button's impression or clicks send signals to Google spiders?
