If there is any nofollow links that means the links pointing from that website provide less SEO value. If there isn't any then the links of the post are dofollow, victory!
Here is a short guide about nofollow and dofollow links.
Dofollow or follow link's HTML code either doesn't contain any rel tags or contain the rel="follow" tag. This means the link is NOT ignored by search engines, so the SEO link juice will be passed to your website, increasing its page rank. Before writing a guest post for any website, make sure you can link to your website with a dofollow link from the article.
Dofollow or follow link's HTML code either doesn't contain any rel tags or contain the following tag: rel="follow". Here are two examples:
Without tag: <a href=”http://www.example.com/”>link text here </a>
With tag: <a href=”http://www.example.com/” rel=”follow”>link text here </a>
The HTML code of a nofollow link contains the rel="NOFOLLOW" tag which tells search engines to ignore that link. Let's say you publish a guest post on a website with a link pointing to your website. If the rel="nofollow" tag is added to the link (done automatically by the website), then your website won't get any SEO value from that website since nofollow links DON'T pass SEO link juice, not improving your website's page rank. But readers can still visit your site by clicking that link.
Here is how the HTML code of a nofollow link looks: <a href=”http://www.example.com/” rel=”nofollow”>link text here </a>
