How to prevent Google from crawling our product filter?
-
Hi All,
We have a crawler problem on one of our sites www.sneakerskoopjeonline.nl.
On this site, visitors can specify criteria to filter available products. These filters are passed as http/get arguments. The number of possible filter urls is virtually limitless.
In order to prevent duplicate content, or an insane amount of pages in the search indices, our software automatically adds noindex, nofollow and noarchive directives to these filter result pages. However, we’re unable to explain to crawlers (Google in particular) to ignore these urls.
We’ve already changed the on page filter html to javascript, hoping this would cause the crawler to ignore it. However, it seems that Googlebot executes the javascript and crawls the generated urls anyway.
What can we do to prevent Google from crawling all the filter options?
Thanks in advance for the help.
Kind regards,
Gerwin

The following is added to our robots.txt .. now lets wait and see the results
User-agent: * Disallow: /admin/
Disallow: /?
Allow /?product_date=&product_date2=*
Disallow /?product_date=&product_date2=&To check the working of the robots.txt i found a handy website;

The url looks like this;
http://www.sneakerskoopjeonline.nl/herensneakers?product_brand=
So just adding;
User-agent: *
Disallow: /*?product_brandShould do the trick?
Most important is that herensneakers itself should be indexed, followed and crawled -
I would use your robots.txt file to prevent them from crawling the specific strings / pages. Go into your Google Webmaster Tools and you can see all the information Google has on your site and any issues, you can also specify robots.txt information in there. That would be the best route as Google is obedient with what is on the robots.txt file. If you want more information about robots.txt, go here.

Inactive Products - Inactive URLs
Hi, In our website www.viatrading.com we have many products that might be in stock or not depending on availability. Until now, when a product was not available anymore, we took this page down (and redirected to its product category page). And, only if the product was available again, we re-activated the URL - this might be days, months or even years later. To make this more SEO-friendly, we decided now that while a product is not available, instead or deactivating/redirecting the page, we will leave it online and just add a message saying "This product is currently not available". If we do this, we will automatically re-activate about 500 products pages at once. 1. Just to make sure, is it harmful for SEO to keep activating/deactivating URLs this way? 2. Since most of these pages have been deindexed for a long time due to being redirected - have they lost all their SEO juice? 3. How can we better activate these old 500 pages - is it ok activating them all at once? Thank you,

Google Adsbot crawling order confirmation pages?
Hi, We have had roughly 1000+ requests per 24 hours from Google-adsbot to our confirmation pages. This generates an error as the confirmation page cannot be viewed after closing or by anyone who didn't complete the order. How is google-adsbot finding pages to crawl that are not linked to anywhere on the site, in the sitemap or linked to anywhere else? Is there any harm in a google crawler receiving a higher percentage of errors - even though the pages are not supposed to be requested. Is there anything we can do to prevent the errors for the benefit of our network team and what are the possible risks of any measures we can take? This bot seems to be for evaluating the quality of landing pages used in for Adwords so why is it trying to access confirmation pages when they have not been set for any of our adverts? We included "Disallow: /confirmation" in the robots.txt but it has continued to request these pages, generating a 403 page and an error in the log files so it seems Adsbot doesn't follow robots.txt. Thanks in advance for any help, Sam

How does google recognize original content?
Well, we wrote our own product descriptions for 99% of the products we have. They are all descriptive, has at least 4 bullet points to show best features of the product without reading the all description. So instead using a manufacturer description, we spent $$$$ and worked with a copywriter and still doing the same thing whenever we add a new product to the website. However since we are using a product datafeed and send it to amazon and google, they use our product descriptions too. I always wait couple of days until google crawl our product pages before i send recently added products to amazon or google. I believe if google crawls our product page first, we will be the owner of the content? Am i right? If not i believe amazon is taking advantage of my original content. I am asking it because we are a relatively new ecommerce store (online since feb 1st) while we didn't have a lot of organic traffic in the past, i see that our organic traffic dropped like 50% in April, seems like it was effected latest google update. Since we never bought a link or did black hat link building. Actually we didn't do any link building activity until last month. So google thought that we have a shallow or duplicated content and dropped our rankings? I see that our organic traffic is improving very very slowly since then but basically it is like between 5%-10% of our current daily traffic. What do you guys think? You think all our original content effort is going to trash?

How to find all indexed pages in Google?
Hi, We have an ecommerce site with around 4000 real pages. But our index count is at 47,000 pages in Google Webmaster Tools. How can I get a list of all pages indexed of our domain? trying to locate the duplicate content. Doing a "site:www.mydomain.com" only returns up to 676 results... Any ideas? Thanks, Ben

Google is mixing subdomains. What can we do?
Hi! I'm experiencing something that's kind of strange for me. I have my main domain let's say: www.domain.com. Then I have my mobile version in a subdomain: mobile.domain.com and I also have a german version of the website de.domain.com. When I Google my domain I have the main result linking to: www.domain.com but then Google mixes all the domains in the sites links. For example a Sing in may be linking mobile.domain.com, a How it works link may be pointing to de.domain.com, etc What's the solution? I think this is hurting a lot my position cause google sees that all are the same domain when clearly is not. thanks!!

Url structure for multiple search filters applied to products
We have a product catalog with several hundred similar products. Our list of products allows you apply filters to hone your search, so that in fact there are over 150,000 different individual searches you could come up with on this page. Some of these searches are relevant to our SEO strategy, but most are not. Right now (for the most part) we save the state of each search with the fragment of the URL, or in other words in a way that isn't indexed by the search engines. The URL (without hashes) ranks very well in Google for our one main keyword. At the moment, Google doesn't recognize the variety of content possible on this page. An example is: http://www.example.com/main-keyword.html#style=vintage&color=blue&season=spring We're moving towards a more indexable URL structure and one that could potentially save the state of all 150,000 searches in a way that Google could read. An example would be: http://www.example.com/main-keyword/vintage/blue/spring/ I worry, though, that giving so many options in our URL will confuse Google and make a lot of duplicate content. After all, we only have a few hundred products and inevitably many of the searches will look pretty similar. Also, I worry about losing ground on the main http://www.example.com/main-keyword.html page, when it's ranking so well at the moment. So I guess the questions are: Is there such a think as having URLs be too specific? Should we noindex or set rel=canonical on the pages whose keywords are nested too deep? Will our main keyword's page suffer when it has to share all the inbound links with these other, more specific searches?

Check Google ban on domainname
Hello all, If I wanted to know if a domainname has a google ban on it would the following be a good idea to test it. Place an article on the domain page with unique content and then link to the page so its gets indexed and then link to the article from a well indexed page. If it doesn't get indexed there might be a ban on the page, if it does get indexed there is no ban on the page... Or are there other points I should keep in mind while doing this. All help is very welcome. Cheers, Arnout
