A company I have just started working for in the marketing department unfortuantely has a contract with an SEO agency until June and they rang me today to give me an update and they told me that the site now has 13 links to it, while I was on the phone with them I checked the site in Majestic, Moz & SEMRush and it registered 0 links on all of them! So I told them this and they said they would look into this and this is what I have now been emailed back: "I have now looked a little closer at how it works with the links. It appears that the links are not visible in MOZ or Majestic because of secrecy. Therefore, I can unfortunately not show you these. However, I have looked more closely into our system and it turns out that the total amount of all the links to your site when summed up with sub links are 37." Are they just full of shit? How can you hide links from these tools? Is there a tool I can use to find out the links they are using? Or are they just the worst SEO agency like I think they are?
