Recently, I arranged one link for my client on a website through guest post. The link is a dofollow (atleast in my opinion). However, my client is saying that the link is nofollow and he will not consider it as dofollow.
On analysing the source of the page, I found a very strange html code used for the link. Owing to confidential nature of the deal, I am unable to reveal the actual link but here is the html code for the same:-
<a href="https://www.#.###" rel="dofollow" target="_blank" rel="nofollow">
You can see in the code that while the url of the website is followed by a rel=dofollow tag, the same is immediately followed by a target =_blank which itself is followed by a rel=nofollow tag.
As such, my client is claiming that overall, the link is a nofollow link and we should remove the nofollow tag if we want to get a credit for arranging the same. We are perplexed because it is the first time we have seen the use of both dofollow and nofollow in the same html code.
So my question to all friends here is what should this link be considered? Is it a dofollow or a nofollow? I tried to search on the google but could not find any answer. In one website article, I found about use of noopener or noreferrer tags with rel="nofollow" target=_blank tag for security reason. But nowhere could I find any explanation or even instance of using both the dofollow and nofollow tags in the single link code.
