Are lots of links from an external site to non-existant pages on my site harmful?
-
Google Webmaster Tools is reporting a heck of a lot of 404s which are due to an external site linking incorrectly to my site.
The site itself has scraped content from elsewhere and has created 100's of malformed URLs.
Since it unlikely I will have any joy having these linked removed by the creator of the site, I'd like to know how much damage this could be doing, and if so, is there is anything I can do to minimise the impact?
Thanks!

Thanks for this - definitely some food for thought regarding how we handle 404s in general...
I am more worried about search engines than humans from this type of thing (we have had no referrals from this dodgy site) so would be interested to see if you still think a 301 is the best way to go since the link text may not be appropriate to our site (and perhaps this would be worse?!).

404s are something do be avoided as it makes your website look 'abandoned' in a way. If possible, I would set up 301s or similar to send these links to your main website rather than to 404 pages. You could also create a nice 404 site.

A bit of work can go a long way.

Ranking for non-existing content which is 301 redirected
Hey there, In the beginning of this year I've made complete site migration from Dutch language to English. All the old Dutch URL's were 301 redirected to the English versions. I naturally lost rankings for all Dutch keywords during the next month. On the website there is no Dutch content anymore. But what happened now is that five months later the website started to rank for the Dutch keywords again. The page snippets in SERP are in English but the URL's shown are in Dutch (ending with .nl) and whenever a user clicks on the snippet he/she gets 301 to the correct English version. Any ideas what could be the reason for re-ranking of non-existing pages which gets 301 in SERP?

Adding parameters in URLs and linking to a page
Hi, Here's a fairly technical question: We would like to implement badge feature where linking websites using a badge would use urls such as: domain.com/page?state=texas&city=houston domain.com/page?state=neveda&city=lasvegas Important note: the parameter will change the information and layout of the page: domain.com/page Would those 2 urls above along with their extra parameters be considered the same page as domain.com/page by google's crawler? We're considering adding the parameter "state" and "city" to Google WMT url parameter tool to tel them who to handle those parameters. Any feedback or comments is appreciated! Thanks in advance.

Non-Canonical Pages still Indexed. Is this normal?
I have a website that contains some products and the old structure of the URL's was definitely not optimal for SEO purposes. So I created new SEO friendly URL's on my site and decided that I would use the canonical tags to transfer all the weight of the old URL's to the New URL's and ensure that the old ones would not show up in the SERP's. Problem is this has not quite worked. I implemented the canonical tags about a month ago but I am still seeing the old URL's indexed in Google and I am noticing that the cache date of these pages was only about a week ago. This leads me to believe that the spiders have been to the pages and seen the new canonical tags but are not following them. Is this normal behavior and if so, can somebody explain to me why? I know I could have just 301 redirected these old URL's to the new ones but the process I would need to go through to have that done is much more of a battle than to just add the canonical tags and I felt that the canonical tags would have done the job. Needless to say the client is not too happy right now and insists that I should have just used the 301's. In this case the client appears to be correct but I do not quite understand why my canonical tags did not work. Examples Below- Old Pages: www.awebsite.com/something/something/productid.3254235 New Pages: www.awebsite.com/something/something/keyword-rich-product-name Canonical tag on both pages: rel="canonical" href="http://www.awebsite.com/something/something/keyword-rich-product-name"/> Thanks guys for the help on this.

Internal links to low value pages
Hi, We're doing a big content update on our product pages and I'm looking for some advice about our internal linking. In a nutshell, the current design we're using links out from every product page (i.e. plants) to a set of accessory pages (i.e. things to help you plant the plants). The screenshot shows how this works. The accessories we sell are a very small part of our business and don't attract significant or valuable search traffic. It's the plant pages that pull in the visits and make the money.

The reason for all these links to accessory pages is for usabilty & to reduce the volume of support calls about accessories (we get a lot of those). So my concern is that by linking out to these relatively low value accessory pages from all of our plant product pages, we will be spilling link juice from all our important pages to a small set of unimportant ones. Should I be concerned about this and if so, what should I do differently? I have considered: Making an intermediary page, listing the relevant accessories, so that each product page links to one intermediary page, which then links to all the accessories. Using nofollow on the accessory page links - there is so much info out there about this, much of it conflicting, that I just don't know if that's a good or bad idea. Using some kind of java-based pop-up box to list the accessory links that will hide the links from spiders. Linking back from the accessory pages to the relevant product sub-category pages to loop the flow of link juice. All ideas welcome zoBgC0 -
Any issues with lots of pages issuing 301 redirects?
Hi all, I'm working on a site redesign and it is possible the new site could issue a lot of 301 redirects as we may migrate from one forum solution to another. Is there any issue with crawlers getting a lot of 301 redirects from a site? Thanks Nick

Non existant URLs being generated in index
Hi all, I have a pretty big problem with my site at the moment which I'm worried will have an impact on my rankings. I've just had a crawl test done and for some reason I get a load of urls returned that don't actually exist... For example I am getting urls like this in my crawl test and xml sitemap: www.applicablejobs.com/jobs/add/android-designer/android-designer/android-designer/android-developer/android-developer/ www.applicablejobs.com/jobs/add/android-designer/android-designer/android-designer/android-developer/iphone-designer/ All the urls seem to start off with www.applicablejobs.com/jobs/ and there is an entry for every conceivable combination of slugs. I can only assume that if the crawl test and an xml sitemap generator is indexing these urls then Google and other search engines probably are too. Does anyone have any idea what might be causing this issue and what can I do to remove them from Googles index if they are? Thanks

Adding no follow links on my site
I am getting a warning about having too many links on my page www.accessoriesonline.co.uk (152) but I don't want to remove any links from the site. Its an ecommerce site with categories across the top, featured products and then a further category navigation in the footer. Would it be beneficial if I added a rel="nofollow" to the links in the footer as these are duplicates of the one's in the header or would this harm the links in the header and the destination URL's which I definitely want to be crawled? Also, does anyone know if SEOMOZ considers links with a rel=nofollow as an actually link when they calculate their overview? Thanks in advance
