Why is On-Page showing canonical wrong?

[HarrisonLighting]

I'm trying to use the On-Page report card and it's saying that my rel=canonical is wrong, I've looked and I can't see anything wrong with it, am I missing something?

The url is www.harrisonlighting.co.uk/childrens-lights.html

Hey, it looks okay from a quick view at the page you have listed above. What is the error message you are getting?

[HarrisonLighting]

It's in the on-page, as part of the critical factors, doesn't really give me a reason for the error it just says

<dl>

<dt>Canonical URL</dt>

<dd>"http://www.harrisonlighting.co.uk/childrens-lights.html"</dd>

<dt>Explanation</dt>

<dd>If the canonical tag is pointing to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. Make sure you're targeting the right page (if this isn't it, you can reset the target above) and then change the canonical tag to reference that URL.</dd>

<dt>Recommendation</dt>

<dd>We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply.</dd>

Hey,  I have just  ran that page through the on page optimisation tool and it comes back with no errors, perfect score as it happens. Think it may have just been a bug when you ran it through or some other small problem as it certainly seems fine now.

I would take a look at how you're handling redirects. Any page that I remove the www from the URL takes you to the home page and not the www version of the page. That's a huge mistake. I would suggest fixing that right away.

Thanks I never noticed that, I don't have a clue how to fix it, if I use non-www it takes me to www which is what it should do but it doesn't seem to work if it's in a product, I've tried adding

RewriteCond %{HTTP_HOST} ^www.harrisonlighting.co.uk$ [NC]
RewriteRule ^(.*)$ http://harrisonlighting.co.uk/$1 [R=301,L]

to my htaccess but them the site doesn't work

[irvingw]

try this generic code:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]

Alternatively, try your code but lose the $ at the end of the first line like this:

RewriteCond %{HTTP_HOST} ^www.harrisonlighting.co.uk [NC]
RewriteRule ^(.*)$ http://harrisonlighting.co.uk/$1 [R=301,L]

Thank you your suggestion seems to have fixed it
