Hi Alan,
Nice to see a counter argument - it helps to understand the other side!
Agreed that press releases work in terms of getting your name out there and perhaps they do get you in contact with bloggers etc but there are other ways of doing this, which in my opinion are better. I'm not saying I'm correct, this is all just from experience.
In respect of Mathew's question....
Do Press Releases sites still worth to engage in terms of link building and domain authority building? I heard they don't deliver link authority anymore?
No. The links you get from press releases are usually poor quality and you rely on the fact that you will get many in order to see any benefit. This is not a sustainable link acquisition method and you can make far better use of your time, money and effort than press releases.
Press releases have their role to play in digital marketing but not as a link building tool.
Thanks,
Elias
