Welcome to the Q&A Forum

Thanks for sharing

Actually I also didn't get so much changes form this links!

But I wonder some webmasters say this link will boost your site.

Hi

I read some articles about Wikipedia links but most of them were talking about how to get links from Wikipedia and no one says about its benefits!

We all know that Wikipedia backlinks are nofollow and in most of the articles in Wikipedia, users don't click on the link! So it doesn't pass visitors

so nofollow links don't pass the authority. But because this website has trustworthy links, might effect on serp.

In your experience does Wikipedia links effect on serp?

What grade you will give to this kind of links between one and 100?

Between edu, gov, wiki and such this important links which one is more important?

I will be glad if you share your experience.

Thanks for your reply

Today I redirect most of these links to the right post, but it was such a borning task.

Redirect one by one? its so boring!

Does The section "linked from" updates for these links?

I use redirection plugin instead of htaccess. Its more safe 

What happen if I don't redirect them for recognizing why these errors occur?

Thanks for your respond

Thanks for your perfect answer.

I checked these links in moz link explorer but no link found. i think this is an internal problem because most of my subfolder links (over 70%) become 404.

I have redirection plugin. It has 404 sections that shows last visitors that gone to the 404 pages but no reports like this error found!

As you said it seems I should redirect them with .htaccess

Thanks , I emailed my domain for you.

Can I put my domain here for others to check?

Hi

First of all I should say that I have error in the old webmaster not the new one.

I have two WordPress blog in root and subfolder.

Today I checked my webmaster and recognize that I had 100 errors (404) that found in few days ago.

My root WordPress is OK but subfolder WordPress has error. Let me show you by example.

http://example.com/subfolder/article15245

I had error for this page:

http://example.com/article15245

looks like this subfolder deleted

I checked my links, but all of them were OK and linked to the right URL.

unfortunately this errors dont have "linked from" section
