Press service (Interviews, PR etc) for new tech website?

Hi,

I'm launching a new website in the tech space and want to make sure that there are a number of good, authoritative resources out there so people searching the brand website see interviews and other information about my site.

This is not so much for building back links, but more for a general sense of authority for users seaching for my site.

Any ideas about services like this?

Thanks.

PR servcies can work for both getting information out and as you say the seo benefits are there too.

Look for outreach/ guest posting too, as other methods to consider.

Cool any services apart from press releases you'd recommend?

facebook ads targeting IT group is the better, faster, and "cheaper" option
