Welcome to the Q&A Forum

Thanks Federico and Tim. I had a mistake about this. Dofollow is default

Hello,

My website is http://www.vietnamvisacorp.com is using the href links without meta tag rel="dofollow" such as I am using . Should I put ref="dofollow" in this: 

Thank you!

Hi,

I just did a mobile version (http://m.vietnamvisacorp.com) of my site (http://www.vietnamvisacorp.com). And was looking for some guidance on where to put it in the sitemap. Do i need an entirely new sitemap for mobile site, or do i just add to my existing .xml of desktop site.

Thank you!

I have marked as fix many times, and then the errors still occur. When I check my sitemap and did not see the not found links which are listed in the tab linked from sitempap.

For an example about this problem:

Google webmmaster report Not found link: www.vietnamvisa...com/tips/6.html (this is link before update).
and in the tab Linked from: http://www.vietnamvisacorp.com/tips.html, but in this page did not include /tips/6.html

Hi,

I have a problem with Google Webmaster, it reported that I have many errors 404 Not Found. 
I have detected and found the links are coming from my site, I have fixed them and submit a new sitemap to google again. Then, I wait a few days, google still report errors 404 Not found same as before.

I don't know why? Please help!

Hi,

I saw my website have a problem about meta language, I do some search and found that I need to add  on the , with 'll' is language code and 'cc' is country code.

But I am confused what should I do, because my website is world wide, not launch at specific any language and country. Please give me an advice in this case.

Thanks,

Thank you!
I have just update titles by appending string 'Page 1 of 4' at the end of each page title. This will fix the duplicate page title above.

Hello,

I have a duplicate page title problem: Crawl Diagnostics Reported that my website got **sample URLs with this Duplicate Page Title **between:
http://www.vietnamvisacorp.com/faqs.html and these URLs below:http://www.vietnamvisacorp.com/faqs/page-2
http://www.vietnamvisacorp.com/faqs/page-3
http://www.vietnamvisacorp.com/faqs/page-4
http://www.vietnamvisacorp.com/faqs/page-5

I don't know why, because I have already implemented rel=”next” and rel=”prev” to canonical pages.

Please give me an advice!

Thank you !

I also found a good tool for creating sitemap: http://www.web-site-map.com/xml_sitemap.php

Should I remove www.abc.com/this-is-a-url--1.html from Google use Remove URL - google webmaster tool?

Thanks

Thank you so much !

Both advice are helpful. I agree with both of you, I googled and found some a useful article http://www.isoc.org/inet95/proceedings/PAPER/016/html/paper.html#S4

and then I'd prefer to remove the special character from my URLs. I will ask a developer to do this.

Thanks again!

Hello,

I confused about the parameters when create sitemap.xml. I don'n know how to use these parameters efficiently. Some parameters are: 
- **Page changing frequency: **what is a good value? Can I choose "None"?
- **Last modified date: **what is a good value? Can I choose "Don’t specify"?
- **Page priority: **what is a good value? Can I choose "Don’t specify"?

Thanks,

Hello,

I am using URLs which contain special character such as ', ". I found in the Google Webmaster Tool report errors related URL contain ' character. Google have indexed partial URL from beginning to ' character and cut off the rest of URL. For example: I submitted URL www.example.com/vietnam-visa-corp'-test-page.html, then google report error NOT FOUND for URL www.example.com/vietnam-visa-corp

I don't know why and how to fix it? Please help!

Thanks,

Hi,

I am using Google Webmaster to check 'HTML Improvements' errors and found that I have many Duplicate meta descriptions errors. I think that they occurred because I have change some **old URLs **to **new URLs **and then use redirect 301. This lead meta description of **old URLs **duplicate with meta description of new URLs. For example: old URL: www.abc.com/this-is-a-url--1.html and new URL: www.abc.com/this-is-a-url.html. And then use redirect 301 from www.abc.com/this-is-a-url--1.html to www.abc.com/this-is-a-url.html

Who did face this problem? Please help me how to fix this? Thanks

yes, robots.txt is the bad way, I will try to use canonical tag. Thanks for your help!

I have tried to use cross-domain canonical, but this is too difficult for me. So, I want to confirm if I use the robots.txt file is ok or not?

Thanks
