What are the solutions for Crawl Diagnostics?

[Abhi8187]

Hi Mozers,

I am pretty new to SEO and wanted to know what are the solutions for the various errors reported in the crawl diagnostics and  if this question has been asked, please guide me in the right directions.

Following are queries specific to my site just need help with these 2 only:

1. Error 404: (About 60 errors) : These are for all the PA 1 links and are no longer in the server, what do i do with these?

2. Duplicate Page Content  and Title ( About 5000) : Most of these are automatic URL;s that are generated when someone fills any info on our website. What do I do with these URL;s. they are for example: _www.abc.fr/signup.php?_id=001  and then www.abc.fr/signup.php?id=002 and so on. What do I need to do and how? Plzz.

Any help would be highly appreciated.

I have read a lot on the forums about duplicate content but dont know how to implement this in my case, please advise.

Thanks in advance.

I am glad, I brought it to your notice.

One last question for you, I have put  the canonical of all these PR 1 pages to my home page, is it fine?

Charu, I went through one of my campaigns and it looks like you're right on that.

Thanks, I did what you suggested.

However, after setting the canonical tag, I guess now Moz does not report this asduplicate content or missing/duplicate title, instead it shows this under notices as Rel=Canonical tag.

Please correct me if I am wrong.

404 errors will usually mean that there are active links to pages on your site that don't exist.  You need to find those links using OSE or a tool like screamingfrog and then you need to remove or revise those links.

Duplicate content--add a rel=canonical tag to the header of the www.abc.fr/signup.php page that shows that it is the canonical version. The duplicate versions will then carry the same tag, indicating that the original is the canonical version of the content.  While that's a good practice for the search engines, it won't stop those pages from showing up in Moz's reports as duplicates--they will continue to show up as dupes if they get crawled.
