Dear Sir/Madam! I watched many links that are on the sites/blogs that are not following it but when I searched about it in google, google was indexing it. Question Raises Why? My apology for my wrong and bad english/weak english.. Best Regards.
A link is a link. The rel attribute for nofollow would only stop your website from increasing its page rank,
Its because google doesnt only index dofollow link. As long as your link got a rich content.google will surely consider indexing it.
They are right google crawl every links that you have made but no-follow attribute don't have a value as backlink in google.
Google follows all nofollow links, its just that it does not let page rank flow to the page. I have about 4000 nofollow links in twitter, they do not affect my pagerank. Its like the switzerland of link building.
Think of situations when you want to use nofollow as when you have a valuable, high traffic, authority web site, and you want to provide your readers with a link to a page which is an example of what you recommend they don't do... such as use ugly page design. You want your readers to see the ugly page for instruction by way of example. But you don't want the "ugly" site to benefit from you passing along your link juice for Page Rank purposes. So you would use the "nofollow" tag to prevent it. The search engines will find your link whether it is nofollow or dofollow, but theoretically, nofollow instruct the search engine not to pass along your link juice.
You guys got this all wrong. Someone linked to the page with a do follow link. You need a "noindex" meta tag to prevent it from being indexed. <meta name="robots" content="noindex"> HTML:
Google has consistently said nofollow means exactly that - the lin k is not followed In general, we don't follow them. This means that Google does not transfer PageRank or anchor text across these links. Essentially, using nofollow causes us to drop the target links from our overall graph of the web. However, the target pages may still appear in our index if other sites link to them without using nofollow, or if the URLs are submitted to Google in a Sitemap. Also, it's important to note that other search engines may handle nofollow in slightly different ways. http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=96569 People may say anecdotally that nofollow links appear to be followed, and they do appear in GWT - but - Google says they don't.
Nofollow is just PR calculation. It has nothing to do with indexing. If you want to hide some pages from SE, then use robots.txt
That's what I thought. I use nofollow and unless the pages are linked elsewhere such as a sitemap they won't get indexed. Nofollow just means that particular link is ignored. It's not a replacement for robots.txt disallow.
Of course, Google can get those links with NoFollow tag indexed. NoFollow links mean that this type of link can't pass the link juice.
Main purpose of using NOFOLLOW is not to index link /page by search engines.Google announced in early 2005 that hyperlinks with rel="nofollow" attribute would not influence the link target's Page Rank. In addition, the Yahoo and Bing search engines also respect this attribute.
The anchor text in a link, even if nofollow, still can be of SEO value. This anchor text can tell google what keywords you want your site to be indexed for.
Google just follow the link to see where is that certain link leading to. This could help them analyze overall linking pattern and sometime a website that place outbound link to bad website (aka. bad neighborhood) may get a penalty even that link attached with "nofollow". However, Google does not give any weight to those link anyway. You can see this kind of link in your Google Webmaster Tools account but it does not mean Google does give them a weight. Another of my "own assumption" is, nofollow could be good help keeping your website link profile balanced. It is almost impossible to get all links as "dofollow" if those links come in natural pattern. Many forums do attached "nofollow" to any posted links in threads automatically. If your website homepage or inner page has been referred from some of them then it would be no surprise if those links are nofollow but might give you an unexpected value anyway.
