Social bookmarking will have some edges. One the one side, it’s a link. The quality of the link is vital, of course, as is whether or not or not the link is follow or nofollow. A link from Reddit will vary from worthless to glorious. A link from Folkd is maybe attending to be nugatory at the best.
Social bookmarking may also bring you traffic. Again, posting in a very heavily trafficked sub on Reddit will get you a great deal of clicks and a great deal of eyes on page. whether or not those valuable hits is up within the air, however traffic is traffic. The worst social bookmarking sites aren’t progressing to bring you any traffic in any respect, though.
The first risk is that your links won't be excellent. Even Reddit links aren’t bound to bring you any price. Sure, you'llget plenty of exposure once you’re on the front page of The Front Page Of The Internet, however if you’re posting your link to subs like this one, you'll bet you’re not gaining exposure from it.
The second risk is that the traffic you get typically incorporates a high bounce rate.
And, apart from that, if you bought those links and you found out that they are spammy or not benefitting your site, you’re out the cash you spent on these links. I mean, sure, perhaps you may be obtaining one hundred links for 5$, but you will be disavowing ninety five of these links later.
