Query string parameters and canonical links
-
Hello everyone,
My site uses query string parameters in a few places to manage tasks like pagination of lists. Eg: http://www.example.com/destinations/somewhere?page=2
I have set a canonical link with the href of the page without the query string
but still getting thousands of duplicate title/meta description reports from these pages. Is there something I can do to change this?
Do search engines actually penalise for use of query string parameters like this? They seem so commonplace, even for sites which use an absolute URI with no query string to serve content.
Thanks

The links between the pages should contain rel=prev and rel=next the also help let SE's know that the content is paginated.

If you're getting the dup content error reports in the Moz crawl diagnostics, see the Staff response here: http://moz.com/community/q/duplicate-title-tags-even-with-rel-canonical
As gazzerman1 shared, you should be in the clear from any duplicate content penalties caused by URL parameters, especially with having rel next/prev or canonical tags setup.

There are a few options, you can also implement the noindex no follow on those pages. John Muller at Google has repeatedly said there is no internal duplicate content penalties. However it will need to determine the best page to show, so clear signals like the canonical are good.
You can also look at the "URL Parameters" section in webmaster tools if you are confident you know what you are doing. This can be used to inform Google about query strings you want it to ignore.
There is nothing wrong with query strings, in fact Google has recently said it likes them instead of very long keyword stuffed url's.

Does Google Bias Against Homepages for Search Queries that are a Question?
If you are trying to rank for a keyword phrase that is a question (e.g. how to ___) does it matter if your page is the home page of your site or an article on your site? I suspect that Google would treat question search queries differently and would show preference for articles over a home page in most cases. An article would be more likely to satisfy the searcher by providing the answer to their question, whereas the home page usually doesn't provide specific answers. I looked at one keyword phrase that is a question and only 1 of the first 20 results was a home page. Any thoughts or experience with this?

Change in link structure due to Joomla
Hi, I have been using Joomla 1.5 until recently and the link structure would be something like - http://www.guru99.com/software-testing.html Now with Joomla 1.7 , ".html " automatically stripped and the URL become "http://www.guru99.com/software-testing" My site is due upgrade but ".html" part is a concern. Once I upgrade , Can I re-direct all ".hmtl" url like http://www.guru99.com/software-testing.html to non ".html" url like "http://www.guru99.com/software-testing" Will this ensure all the link juice is passed ? I have more than 350 URL in my site ... Please guide ... Cheers Krishna PS = the link http://www.guru99.com/software-testing will not work since the site is yet to be upgraded

Randomly Generated Links & Passing PageRank
Hi all, If you were to have links that were randomly generated on each refresh, how would they be treated? I would imagine that they are treated normally and isolated to each crawl. So Google would just see the link structure changing from crawl to crawl and therefore give no long term value to these links. Any ideas? Thanks for your responses! Nick

Do external links drain PageRank?
Example: A page has 100 links, 90 internal links and 10 external links. The page has a Google internal PR of 1000. The question is: Is the pagerank that flows to the internal links being calculated taking into account all links on the page (internal + external) or only the 90 internal links? E.g. is the PR that flows to the internal links 1000/100 or 1000/90? Are links to external sites "votes" that do not affect the internal PR flow? Disclaimer: I understand that the maths behind the PR algo are more complex. This simplified example only serves to explain my question.
