<meta name="robots" content="nofollow" /> I have place the above meta tag in every page of my website is it create any problem or is it good for site rank and also for other thing can any one please give me clarity on it.
Hello, There is no biggie here and no cause to fret. You have simply told the bots not to follow any links on the site. You stand to preserve a lot of link juice. Regards
It will also help you to receive the spam comments on your blog post. I also did the same things from my own blogs and you also did the internal linking of every post.
Is this method will increase page rank of the website. can you suggest me nofollow code for internal links.
It you did put this on every page then search engines will find it difficult to navigate/crawl your site for indexing. To overcome this you can submit sitemap for the important pages.
The best solution to this would be adding rel="nofollow" tag automatically to every link submitted with users' posts (if you have a commenting option on your site). Adding content="nofollow" will exclude any link on your site (navigation links or links to articles) and you don't want to do that.
Adding that tag will also hinder your own internal links, which means google will not follow those pages but may index them if it comes across them on other sections/sites.
That's just going to hurt your internal linking and it sure as hell won't help you with anything regards PR because it has nothing to do with PR.
What Slincon says. Perhaps you don't want Google to follow links to other sites, but you'd probably want it to follow links to your own site (internal links). So, i'd use those nofollow tags on a per-link basis.
The per link basis would be good. You hate for a search engine to not crawl you, regardless of what that search engine is.
