Canonical Tag for a 404 page
-
Hi
i have a got a 404 page for example : www.example.com/404.aspx
can i use canonical tag on this page
so that when the search engine hits the page www.example.com/123123123 13123
it will say
Will this be right method ?

The two most important points expressed in this thread of comments are:
- There is a reason for 404s, don't 301 everything
- There is no reason to lose the value of someone linking to your page.
If those 2 statements are true then you should create an individual error page, and then everytime you serve a 404 you should include canonical to that error page. That page should have useful content (explanation of page missing and where you could go), probably a search box, and links to the most valuable content on your site. This satisfies both points.
-
The meta redirect tag will keep the link juice on the 404 handler page and not pass the page rank on to the home page. Something you may want to consider if you have a lot of 404's.

Thanks for your reply,
I have already setted up that and in fact i read something over here...
http://googlewebmastercentral.blogspot.com/2008/08/now-that-weve-bid-farewell-to-soft-404s.html
We feel this technique is fine because it reduces confusion by giving users 10 seconds to make a new selection, only offering the homepage after 10 seconds without the user's input.
But my question is sometimes you can't control how other people linked to you and they link back to us with a url that does not exist. And in googlewebmaster control panel we get an error for the saying Duplicate title - 404 Page Not Found.
For that if i use it should be ok or not

If you love writing code, read on
I like setting my 404 pages to evaluate the incoming URL (the one that failed) and trying to redirect the user to the proper page while 301ing the hand off. If you cannot evaluate the page to a good page, then 301 to the home page. If you can only evaluate to a category level (storefront type site), then 301 them to the category level.
It takes some fiddling around with the code and lookups to the database, but you get a much better experience for the user.

You could but, you would be better creating a search page so 404's go to www.example.com/search.aspx so users can search for the content they were actually looking for in the first place. Ideally all your pages should have the canonical in the head to ensure trailing / or capitalization errors all pass juice to the correct page and do not get reported as duplicates.

Rel Canonical help
Is it possible to confirm this to me please? My understanding of the rel canonical tag was to tell google of duplicate content? so for instance product 1
On-Page Optimization | | TeamacPaints
www.ourdomain.co.uk/products/category/subcategory/theproduct1 Product 1a
www.ourdomain.co.uk/products/category/subcategory/theproduct1a same content just a different colour would be rel canonical'd to Product 1 as thats the main product, is my understanding correct? Now here is what I have discovered. www.ourdomain.co.uk/products/category/subcategory/theproduct1 has a rel canonical tag that reverts back to www.ourdomain.co.uk/products/ which isn't optimized as such its just a generic catalog page. This is inccorect and google will dismiss the actial product and revert to the generic catalog page? any help would be great.0 -
Is it better to create more pages of content or expand on current pages of content?
I am assuming that one way of improving the rankings of current pages will be to create more content on the keywords used... should this be an expansion of the content on current pages I am optimising for a keyword or is it better to keep creating new pages and if we are creating new pages is it best to use an extension of the keyword on the new page – for example if we are optimising one page for ‘does voltage optimisation work’ would it then be worth creating a page optimised for ‘does voltage optimisation work in hotels’ for example and so on? I am guessing maybe both might help, this is just a question I have had from one of my clients.

Which Meta Tags would you recommend having on the pages?
Hello, There are so many different meta tags which you can implement to the header of your website and I'm wanting to get people's opinions on which you feel are worth putting in and which are completely pointless? For example: Author Copyright Language Content-Type Content-Language Distribution Abstract Keywords Description Classification Canonical Expires Revisit-after Rating I look forward to hearing your comments and suggestions.

Removing OLD pages
Dear all, I was removing tons of old pages from my directory (about 400 pages), I was setingup a 404 custom page, all is fine, so when I go to an existing page I get a 404 and redirected to my 404 page. The problem is Google Webmaster tools list all these pages as 404, and never clean my list (1 year til now), so I assume something is wrong. Question what is the best way or natural to remove old pages from one directory? Note: previously I tryed add on these pages the NOINDEX/NOFOLLOW meta tag and I got from google Soft-404. Thank you

Title Tag To Long
In the initial review of my site, I have 38 warnings of title tags to long. It also says these warnings are often penalized by search engines. In Google webmaster tools, It says I have no problems with long title tags. So am I getting penalized and do I need to shorten them? I would already have shortened them but in the past, everytime I have changed my title tag I have been penalized by the search engines. I usually get my rankings back but it can take up to a month and a half to get back to where I was.

Is there a SEO penalty for multi links on same page going to same destination page?
Hi, Just a quick note. I hope you are able to assist. To cut a long story short, on the page below http://www.bookbluemountains.com.au/ -> Features Specials & Packages (middle column) we have 3 links per special going to the same page.

1. Header is linked
2. Click on image link - currently with a no follow
3. 'More info' under the description paragraph is linked too - currently with a no follow Two arguments are as follows:
1. The reason we do not follow all 3 links is to reduce too many links which may appear spammy to Google. 2. Counter argument:
The point above has some validity, However, using no follow is basically telling the search engines that the webmaster “does not trust or doesn’t take responsibility” for what is behind the link, something you don’t want to do within your own website. There is no penalty as such for having too many links, the search engines will generally not worry after a certain number.. nothing that would concern this business though. I would suggest changing the no follow links a.s.a.p. Could you please advise thoughts. Many thanks Dave Upton [long signature removed by staff]0 -
Potential Duplicate Title Tags On Sibling Pages
Edit I'll take the fall on this one, seems I could have asked my quesiton in a more clear manner. I was cruising other questions and finding a whole of answers that I suspect were not truly intended to help, but maybe help and earn Mozpoints. Wasn't fair of me to label those answering here with that. I will work better on the wording of my questions! 🙂 Edit Either I am asking my question poorly or I am learning there may be a rush to get points by throwing up any old answer...it very well may be the former which I am open to feedback on. Each page is to stand alone and hopefully rank well for the neighbourhood name and in conjunction with another relevant keyword phrase. There is no 'duplicate' version of any pages. * On a site there are numerous pages that provide real estate listings broken down by neighbourhood. Each containing similar content, a abbreviated version of the listings, often spanning 2 or 3 pages. These are 3rd level pages. Properties->Calgary Neighbourhoods->Evanston The title tags created are: Evanston Homes For Sale - NW Calgary Real Estate Panorama Hills Home For Sale - NW Calgary Real Estate Etc. for about 15 or so pages. Then they start again for another area of the city: Sagewood Homes For Sale - Airdrie Real Estate Woodside Homes For Sale - Airdrie Real Estate At this point there is no text on the actual page outside of the listings...an example of similar listings on another site - http://www.experiencerealtygroup.com/BaturynandDunluceHomes.ubr Do you think the SE's will see these as 'proper' use of the Title Tag or duplicate or other practices they tend to frown upon? It is a logical way of creating the title and obviously creating a unique version for each page would not only be tough to scale on some sites with 100's of these pages, they would become a little silly and not much use to the searcher in the SERPs Thanks for any help!
