Please help me about what percentage of anchor text should be use in website which not look like keyword stuffing or over use of anchor text ?
Hi, before suggestion for keyword density was like 3 to 4%, but mu suggestion is that make the keyword density not more that 1 or 2%. Also do not write content keyword based, write content topic based. If your keywords are like "sell gold jewelry", "buy gold", then its not that you put the keywords and google will rank, write only informative content on the particular topics that helpful for user.
Percentage of anchor text on website should be on an average 3-4% but your keyword must be come in content naturally don't try to insert it forcefully or you'll be penalized by search engine in their ranking.
You don't have to pay attention on the keywords if you write on a specific topic. Try to make it look natural. In fact, the 1-3% is a number that corresponds to the natural writing a text on the subject. You can always use the word close to significant.
Forget about keyword density in your blog posts or other pages of your website. Just write for human beings and make your content great and appealing for visitors. Search Engines would reward you for that and keywords would come floating as well.
