Q: And what is the AHREF?
Answer. As the Google search engine starter guide explains, you want to embed your keywords in the anchor tags. The anchor tag is also called the a href tag and what it does is allow for a clickable link from one webpage to another webpage, or from one website to another website.
So the first take away is as you build out your website know your keywords and cross link your webpages to each other around your 5 to 10 primary keywords. This is called link sculpting.
Secondly as you go and get links from other websites to your own website be aware of the anchor tag and its relationship to keywords. However, here is where it gets interesting! In the olden days prior to the Penguin update, I would have advised you to get a lot of links that have the keyword embedded in the anchor text. However, after the Penguin update, it is clear that Google penalizes websites that over optimize.
So the third take away here is in terms of external websites solicit quality links, but do not overdo the use of keywords in the anchor tag. On your own website however, or in contrast, I do think it is still useful to sculpt those links around keywords
