There is no relatino between these terms. Both have their own use and means. Nofollow is tag attribute of anchor link while indexing means crawling of site / pages by google or search engine bot.
indexing is keeping the web page in data base, whereas no follow is an instruction to Google boot the link is not recommended
Absolutely right, there is no relation exists between these two term both were were relates to different origins.
indexing = google crawl our site quickly by adding sitemap.xml nofollow = if we dont want to crawl our particular page means we need to add robot.txt ex: user agent:google disallow:/login.html
The nofollow tag has nothing to with robots.txt file. The robots.txt file is used to tell google and other search engines which pages of your site to crawl. On the other nofollow tag is meant to convey to the search engine that this link to which this nofollow tag has been applied should not be taken into consideration for search engine rankings. This nofollow tag is quite seriously follwed by Google except in some situations, while the robots.txt file is more of an advisory. The search engines can choose to follow it or not.
Nofollow - the google does not follow the link. It just does not enter it. noindex - the bot goes to the site, but it is told not to add the content in google results
Hi In case of indexing your webpage is index by google or other search engines. And if you are using nofollow then your link is not crawled by the search engine. Hope you understand.
