Blocking URL's with specific parameters from Googlebot
-
Hi,
I've discovered that Googlebot's are voting on products listed on our website and as a result are creating negative ratings by placing votes from 1 to 5 for every product. The voting function is handled using Javascript, as shown below, and the script prevents multiple votes so most products end up with a vote of 1, which translates to "poor".
How do I go about using robots.txt to block a URL with specific parameters only? I'm worried that I might end up blocking the whole product listing, which would result in de-listing from Google and the loss of many highly ranked pages.
DON'T want to block:
http://www.mysite.com/product.php?productid=1234
WANT to block:
http://www.mysite.com/product.php?mode=vote&productid=1234&vote=2
Javacript button code:
onclick="javascript: document.voteform.submit();"
Thanks in advance for any advice given.
Regards,
Asim -
Good to hear, I am glad you perservered
-
Tried them all now and all come back with "Success"... May be I'll post in the WMT Forum and see if anyone can shed light on this problem. Thanks for your help Alan, it's much appreciated.
-
Yes correct, did you try the other formats?
-
Tried "Fetch as Googlebot" in Diagnostics and it came back as "Success" so I guess the robots.txt directive is not working. I'm assuming it should have reported a failure message when attempting to fetch a URL containing "?mode=vote".
-
Wrong place, go to diagnostics, then look for fetch as googlebot
-
I added "Disallow: /mode=vote" to the robots.txt file and also manually entered it on Crawler Access page, then clicked "Test" and no errors were reported. The WMT page states that robots.txt was last downloaded 16 hours ago so I'll wait until it picks the file up again and then check for any errors. Hopefully that will do trick
-
Try this in robots.txt, I did not think that Google allows wild cards but i just read that they do.
Disallow: /*mode=vote*orDisallow: /*mode=voteorDisallow: /*modeThen try in Google WMT to read with googlebot to see if it works.The first in the list seems right to me, but I have seen others do it the other ways. -
Thanks for the reply. The site was developed using PHP, mySQL and Javascript. I was hoping there was a way to do it without getting programmers involved...
-
dont think you are going to do it in robots.txt, rather do a 301 from mode=vote to non mode vote.
If you dont know how to put this into practise, tell me what your site is built with, if it is ASP.NET, i will show you how to impliment, if not someone else should be able to help.

How do I deindex url parameters
Google indexed a bunch of our URL parameters. I'm worried about duplicate content. I used the URL parameter tool in webmaster to set it so future parameters don't get indexed. What can I do to remove the ones that have already been indexed? For example, Site.com/products and site.com/products?campaign=email have both been indexed as separate pages even though they are the same page. If I use a no index I'm worried about de indexing the product page. What can I do to just deindexed the URL parameter version? Thank you!

My old URL's are still indexing when I have redirected all of them, why is this happening?
I have built a new website and have redirected all my old URL's to their new ones but for some reason Google is still indexing the old URL's. Also, the page authority for all of my pages has dropped to 1 (apart from the homepage) but before they were between 12 to 15. Can anyone help me with this?

How Does Dynamic Content for a Specific URL Impact SEO?
Example URL: http://www.sja.ca/English/Community-Services/Pages/Therapy Dog Services/default.aspx The above page is generated dynamically depending on what province the visitor visits from. For example, a visitor from BC would see something quite different than a visitor from Nova Scotia; the intent is that the information shown should be relevant to the user of that province. How does this effect SEO? How (or from what location) does Googlebot decide to crawl the page? I have considered a subdirectory for each province, though that comes with its challenges as well. One such challenge is duplicate content when different provinces may have the same information for some pages. Any suggestions for this?

How Does Google's "index" find the location of pages in the "page directory" to return?
This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched. These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory". The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls. Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

Best Practices for adding Dynamic URL's to XML Sitemap
Hi Guys, I'm working on an ecommerce website with all the product pages using dynamic URL's (we also have a few static pages but there is no issue with them). The products are updated on the site every couple of hours (because we sell out or the special offer expires) and as a result I keep seeing heaps of 404 errors in Google Webmaster tools and am trying to avoid this (if possible). I have already created an XML sitemap for the static pages and am now looking at incorporating the dynamic product pages but am not sure what is the best approach. The URL structure for the products are as follows: http://www.xyz.com/products/product1-is-really-cool
Technical SEO | | seekjobs
http://www.xyz.com/products/product2-is-even-cooler
http://www.xyz.com/products/product3-is-the-coolest Here are 2 approaches I was considering: 1. To just include the dynamic product URLS within the same sitemap as the static URLs using just the following http://www.xyz.com/products/ - This is so spiders have access to the folder the products are in and I don't have to create an automated sitemap for all product OR 2. Create a separate automated sitemap that updates when ever a product is updated and include the change frequency to be hourly - This is so spiders always have as close to be up to date sitemap when they crawl the sitemap I look forward to hearing your thoughts, opinions, suggestions and/or previous experiences with this. Thanks heaps, LW0 -
What's the SEO impact of url suffixes?
Is there an advantage/disadvantage to adding an .html suffix to urls in a CMS like WordPress. Plugins exist to do it, but it seems better for the user to leave it off. What do search engines prefer?

Should we use Google's crawl delay setting?
We’ve been noticing a huge uptick in Google’s spidering lately, and along with it a notable worsening of render times. Yesterday, for example, Google spidered our site at a rate of 30:1 (google spider vs. organic traffic.) So in other words, for every organic page request, Google hits the site 30 times. Our render times have lengthened to an avg. of 2 seconds (and up to 2.5 seconds). Before this renewed interest Google has taken in us we were seeing closer to one second average render times, and often half of that. A year ago, the ratio of Spider to Organic was between 6:1 and 10:1. Is requesting a crawl-delay from Googlebot a viable option? Our goal would be only to reduce Googlebot traffic, and hopefully improve render times and organic traffic. Thanks, Trisha

Does 'framing' a website create duplicate content?
Something I have not come across before, but hope others here are able offer advice based on experience: A client has independently created a series of mini-sites, aimed at targeting specific locations. The tactic has worked very well and they have achieved a large amount of well targeted traffic as a result. Each mini-site is different but then in the nav, if you want to view prices or go to the booking page, that then links to what at first appears to be their main site. However, you then notice that the URL is actually situated on the mini-site. What they have done is 'framed' the main site so that it appears exactly the same even when navigating through this exact replica site. Checking the code, there is almost nothing there - in fact there is actually no content at all. Below the head, there is a piece of code: <frameset rows="*" framespacing=0 frameborder=0> <frame src="[http://www.example.com](view-source:http://www.yellowskips.com/)" frameborder=0 marginwidth=0 marginheight=0> <noframes>Your browser does not support frames. Click [here](http://www.example.com) to view.noframes> frameset> Given that main site content does not appear to show in the source code, do we have an issue with duplicate content? This issue is that these 'referrals' are showing in Analytics, despite the fact that the code does not appear in the source, which is slightly confusing for me. They have done this without consultation and I'm very concerned that this could potentially be creating duplicate content of their ENTIRE main site on dozens of mini-sites. I should also add that there are no links to the mini-sites from the main site, so if you guys advise that this is creating duplicate content, I would not be worried about creating a link-wheel if I advise them to link directly to the main site rather than the framed pages. Thanks!
