Does "?" in my URL have a negative effect?
-
I am having a difficult time finding specific information about the effect, if any, having a ? within the URL structure. We have the descriptive keyword phrase followed by the ? location id as in this example:
http://www.adventuresonly.com/adventure-locations/things-to-do-in-arizona?stateid=124
Any feedback on effect and a corrective process to improve if necessary would be appreciated!
-
The question mark sign signals the beggining of URL parameters. This will not impact your keyword however if the URL parameters do not significantly alter the content of you page then this could cause duplicate content issues as Search engines will see each parameter variation as a unique URL.
Search engines will try to identify these but to help them out you should Discount URL parameters in Webmaster tools for the respective search engine (Not just Google), and to avoid link equity being lost or dilluted implementing the Rel=cannonical tag to the page and referenceing back to a sensible root page version will mean all your inbound links work together.
Hope this helps.

I'm struggling to understand (and fix) why I'm getting a 404 error. The URL includes this "%5Bnull%20id=43484%5D" but I cannot find that anywhere in the referring URL. Does anyone know why please? Thanks
Can you help with how to fix this 404 error please?

Changing Urls
Hi All, I have a question I hope someone can help me with. I ran a scan on a website and it has a stack of urls that are far too long. I am going through and changing the urls to shorter ones. But my question is regarding redirections. Wordpress seems to be automatically redirecting the old urls to the new ones, should i be adding a more solid 301 in as well or is the wordpress redirect enough? I ask as they dont all seem to stay redirecting Thanks in advance for the help

What to do with "show all" page
Hello, What should I do with the following situation: In e-commerce shop I have an option to "show all products" (list all products in one page) - do I need to put canonnical or 301 redirect to somewhere or should I leave as normal page - I think google consider this is as duplicate since everything is the same (only number of products is different) ? Regards, Nenad

Structure of urls
**Hallo from Athens, Greece. We have to implement the following project and i need your help: ** We will build a company guide for the whole country and company local guides for each city for the same client. **Information of the country guide is the sum of information of local guides, so when a user is at the country guide he sees information from companies from all cities and when the user is at city guide he sees info only for the city. ** The problem is the structure of the url we should have. Should the page of presentation of each company should have structure as domain.gr/id/company? or city.domain.gr/id/company and the one to be canonical to the other? is this good for seo? Should both urls be included in the sitemap? Thank you

Changing all urls
A client of mine has a wordpress website that is installed in a directory, called "site". So when you go to www.domain.com you are redirected to www.domain.com/site. We all know how bad it is to have a redirect fron your subdomain to another page. In this case I measured a loss of 5 points of page authority. The question is: what is the best practice to remove the "site" from the address and changing all the urls? Should I use the webmaster tool to tell to Google that the site is moving? It's not 100% true, cause the site is just moving one level up. Should I install a copy of the website under www.domain.com and just redirect 301 every old page to its new url? This way I think the site would be deindexet for 2/3 months. Any suggestions or tips welcome! Thanks DoMiSol

Rel="canonical" for PFDs?
Hello there, We have a lot of PDFs that seem to end up on other websites. I was wondering if there was a way to make sure that our website gets the credit/authority as the original creator. Besides linking directly from the PDF copy to our pages, is anyone aware of strategy for letting Google know that we are the original publishers? I know search engines can index HTML versions of PDFs, so is there anyway to get them to index a rel="canonical" tag as well? Thoughts/Ideas?
