Look at the points mentioned below and try to follow for quick approval:
A. Use keyword as anchor text for internal links. Anchor texts are the clickable words which we provide in any clickable link. For internal link HTML tag should be like this:
<a href="/forum/146904-Size-of-images-Policy-change.aspx">ISC's new image policy</a>
The anchor text in above code is "ISC's new image policy".
B. But while we use external clickable links, we have to be more cautious. Point to be noted that we should not use any keyword as anchor text for external link. Try to use name of the site or product or even url itself as anchor text.
1. Add target="_blank" and rel="nofollow" in above link if you are providing any clickable link of private / third party sites like Airtel, Reliance etc. In that case, the code should be written like this:
<a href="http://www.rcom.co.in" rel="nofollow" target="_blank">Reliance official website</a>
2. Add only target="_blank" and don't use rel="nofollow" for the external link to government sites, university websites, reputed colleges etc. While you are not using rel="nofollow" attribute in any HTML tag for clickable link, it is called 'do-follow' itself. However, the HTML tag should be as follow:
<a href="https://eaadhaar.uidai.gov.in/" target="_blank">https://eaadhaar.uidai.gov.in/</a>
3. In case the site name or product name itself is keyword and you have no other option but to use it as anchor text, you should add rel="nofollow" in the HTML tag positively. It is must for the link to government or high-authority sites also.
4. ISC does not encourage external link to any small site or personal blog except if it is truly essential for the article and for that link you should follow point no. 1.
"Respect should be earned instead of demanding."
