Canonical tag vs 301
-
What is the reason that 301 is preferred and not rel canonical tag when it comes to implementing redirect. Page rank will be lost in both cases. So, why prefer one over the other ?
-
page 1 points to page 2 that points back to page 1.. this or simular situations will make fubar for Google
you can actualy do the same with 301's but it's wayyyy easier to notice.. the rel is allot harder to notice if you do something wrong since it only affects google/bing
-
Thanks. Will you please elaborate how it's possible to make an infinite loop with rel's.
-
301 is a redirect so if you change the url you 301 redirect it to the new url in case links have been built to the old url.
rel canonical is a tag that tells Google this page has similar content to another page to help duplicate content issues, usually used on re-ordering functionality and paging.
-
The quick response to this, is that with 301 your fairly sure that all bots (not only google/Bing) will understand and apart from that it's way easier to manage the 301's then it is to manage rel's. Both should work without a problem but there are allot of pitfalls with rel's fore instance it's possible to make an infinite loop with rel's.

Meta Tags (again)
Hey, I know this has been discussed to death but look back through previous postings there doesn't seem to be a consensus on the exact Meta tags that an eCommerce site should include, specifically whether to remove the keyword tag or not since it is believed that Yahoo potentially still makes use of it. Currently our homepage has the following Meta Tags: <title>Buy Printer Cartridges | Ink and Toner Cartridge for Inkjet and Laser Printers</title> Description" content="<a class="attribute-value">Visit Refresh Cartridges for great prices on ink cartridges, toner cartridges, ink, printers and accessories.</a>" /> Keywords" content="<a class="attribute-value">ink cartridges, cheap cartridges, inkjet cartridges, inkjet ink cartridges, ink cartridge, printer ink cartridges, laser cartridges, toner, laser printers</a>" /> Content-Type" content="<a class="attribute-value">text/html; charset=iso-8859-1</a>"/> author" content="<a class="attribute-value">Ink Cartridges, Inkjet Cartridge, Printer Cartridge, Toner Cartridges Refresh Cartridges</a>" /> expires" content="<a class="attribute-value">0</a>" /> robots" content="<a class="attribute-value">noodp,index,follow</a>" /> Language" content="<a class="attribute-value">English</a>" /> Cache-Control" content="<a class="attribute-value">Public</a>" /> verify-v1" content="<a class="attribute-value">sJXqAAWP6ar/LTEOMyUgG6nqothxk62tJTid+ryBJxo=</a>" /> viewport" content="<a class="attribute-value">width=1024</a>" /> This is too messy but before I do something drastic that I'll possibly regret please can you confirm that, in your opinion, I am best to remove everything with the exception of this: <title>Buy Printer Cartridges | Ink and Toner Cartridge for Inkjet and Laser Printers</title> Description" content="<a class="attribute-value">Visit Refresh Cartridges for great prices on ink cartridges, toner cartridges, ink, printers and accessories.</a>" /> Content-Type" content="<a class="attribute-value">text/html; charset=iso-8859-1</a>"/>

viewport" content="<a class="attribute-value">width=1024</a>" /> I realise there is a verify-v1 tag in there but this can be done through a file on our server so while cleaning up that might as well go. Would there be an argument for keeping any of the other tags or are they all pretty much redundant now? Many thanks! Chris0 -
Wildcard Redirects & Canonical Tags
I have an interesting situation. Current URLs Example1: www.domain.com/red-widgets-cid-1234.html
Intermediate & Advanced SEO | | NakulGoyal
www.domain.com/red-widgets-cid-1234-1.html
www.domain.com/red-widgets-cid-1234-1-1.html Canonical on All Above URLs:
www.domain.com/red-widgets-cid-1234.html New URL:
www.domain.com/red-widgets-cid-4567.html Current URLs Example2: www.domain.com/red-widgets-cid-1234+10.html
www.domain.com/red-widgets-cid-1234+10-1.html
www.domain.com/red-widgets-cid-1234+10-1-1.html Canonical on All Above URLs:
www.domain.com/red-widgets-cid-1234+10.html New URL:
www.domain.com/red-widgets-cid-6789.html Current URLs Example3: www.domain.com/red-widgets-cid-1234+10+5.html
www.domain.com/red-widgets-cid-1234+10+5-1.html
www.domain.com/red-widgets-cid-1234+10+5-1-1.html Canonical on All Above URLs:
www.domain.com/red-widgets-cid-1234+10+5.html New URL:
www.domain.com/american-red-widgets-cid-6789+5.html I want to make sure all variations of the above URL redirect to the new URLs. However, as you see in Example 3, we are dealing with variables that are passed on. (+5 in this case). Question 1: What wildcard 301 redirect / regular expression can I use to tackle these ? Question 2: If we redirect www.domain.com/red-widgets-cid-1234+10+5.html to www.domain.com/red-widgets-cid-6789+5.html and www.domain.com/red-widgets-cid-6789+5.html contains the canonical tag www.domain.com/american-red-widgets-cid-6789+5.html, any concerns or red flags here ?0 -
Which index page should I canonical to?

On the index page, I have the following: I have never put any thought into which index path is the best to use. http://www.example.com http://www.example.com/ http://www.example.com/index.php Could someone shed some light on this for me? Does it make a difference? Thanks! Ryan

301 redirect for duplicate content
Hey, I have just started working on a site which is a video based city guide, with promotional videos for restaurants, bars, activities,etc. The first thing that I have noticed is that every video on the site has two possible urls:- http://www.domain.com/venue.php?url=rosemarino
Intermediate & Advanced SEO | | AdeLewis
http://www.domain.com/venue/rosemarino I know that I can write a .htaccess line to redirect one to the other:- redirect 301 /venue.php?url=rosemarino http://www.domain.com/venue/rosemarino but this would involve creating a .htaccess line for every video on the site and new videos that get added may get missed. Does anyone know a way of creating a rule to rewrite these urls? Any help would be most gratefully received. Thanks. Ade.0 -
Tread of backlinks after 301
After 301-ing a domain to a new domain, how should we tread the changing of the backlinks to the old domain? We might be able to have a certain amount changed rather quickly. Should we consider the new domain as a "new" domain, and in this sense, not have them changed quickly, (afraid to trip any filter) Or wil Google see the new domain (after indexing) with the authority of the old domain, so , if the backlinks are direct or coming through a 301 will make no difference? Hope my question is clear and excuses for my english 😛 Thanks for reading and hoping for input,

301 - do i change old links once 301 is in place?
Hey all, I'm about to setup a 301 on a website that has pretty good SEO rankings and I have the ability to change all the old inbound links that point to the old site, to the new site - should I leave them pointing to the old site that has the 301 on it or change all the old inbound links to the new domain name? Which has better SEO value? Thanks for helping, Anthony

Canonical tag for similar page with different theme.
Our commerce system allows products to be shared across multiple categories/sections of our site. E.G. /boxes/blue-box.html /circles/blue-box.html This enables the product to show up in different areas of the site, but does not link to an evergreen URL. We are considering using the canonical tag to resolve this issue, but our question relates to the similarity of the pages. Each section folder (e.g. /boxes/ and /circles/) has a different header, left navigation and footer. They are similar in layout and some content is the same, but a good portion is different in the header and nav. Each category nav basically deals with deeper links in it's own category. The product title, image, description, etc. is all the same and makes up the bulk of the page. Is this a good candidate for the canonical tag or should we attempt to accommodate an evergreen URL?
