Is press release the same thing as , journalists/newspapers? If so, get link from journalists/newspapers will not be devalued? If not, what is different between press release submission and pitching stories to journalists/newspapers?
If you get editorially earned links from journalists in well respected newspapers . . . those links will be valuable. In theory, a press release distribution site should distribute your press release to a selection of relevant journalists which would mean that if you've produced a usefull press release, you have more chance of the journalist using it and earning an editorial link So . . . the real aim of submitting to press release wires isn't to get a link from that site itself . . . more to encourage links from journalists.
