Welcome to the Q&A Forum

Congratz on the publicity! Those are some great links! Unfortunately though, Google may be ignoring them because they contain the tag rel="nofollow" which basically tells Google (and other search engines) not to follow it. The Daily Mail one definitely does, so I would check the others too. Many big publishers will nofollow external links, as they can't "vouch" for what they're linking to and don't want to risk the association. Though the mention of your site, even with a nofollow link, isn't without benefit to your website! The Daily Mail one alone has a page authority of 51 and a domain authority of 94, so being linked to from there is impressive. It puts your website in a "good neighbourhood", so to speak. But just not as SEO-effective as it would have been if it were followed. If the link doesn't contain the rel="nofollow" tag then it doesn't matter if the link was added after Google first indexed it. If Google crawls the page again, after the link was added, it would count it.
