The importance of social bookmarks for SEO

1. Social Bookmarks
The most people that works in online marketing know that manual bookmarks are the best and safest for SEO campaigns.
But among thousands of manual bookmarking services, you should know that some are good to get only social presence and
others to get more benefits, such as new visitors from social media, viral marketing, targeted traffic, improve ranking positions
in search results, improve the pagerank, etc.
Get social media presence
For this is enough to submit your link via social profiles with a low number of followers, friends or connections. You'll get a
little advantage from that kind of social accounts: your link will be faster indexed. Nothing more, so be carefull to not manually
submit your url to tens of social bookmarking sites (10 - 20 are enough). For example, here you can find cheap social
bookmarks!
Stay at least on Top 5 Social Bookmarking Sites
The top is created from the pagerank point of view:
Twitter - PR10
Facebook - PR9
LinkedIn - PR9
MySpace - PR9
Pinterest - PR8
But you wouldn't limit only to TOP 5:
Stumbleupon - PR8
Google Plus - PR8
Delicious - PR8
Identica - PR8
MyOpera - PR8
PR8 Plurk - PR7
FriendFeed - PR7
BuzzFees PR7

2. Social accounts with many connections
This means that a social profile get a greater value as many friends/followers/connections it will grab. It's like the backlinks for
a webpage: get more incoming links from other webpages (social profiles) and your authority will grow. I recommend to buy
bookmarking services only from accounts with at least tens of followers. So, do not hesitate to ask about the number of
friends or followers of the social profiles that will bookmark your link. Also, as many connections a social profile have, more
visitors and reactions (likes, shares, comments) you'll get.
Old social profiles, usually with PR1+
The age of a social profile certify the authority of that account, as well as its activity. Also, many social accounts, older than 1
year have pagerank, usually PR2, PR3 or more - and this helps your link to be almost real time indexed and to get traffic from
search engines. Also, that's a good reason to use a White Hat SEO freelancer.
Use linked social accounts!
Almost social bookmarks have advanced options that allow you to automatically share your posts. So, you have the
opportunity to post i.e. on Pinterest, to share on Twitter and in the same time to share the Twitter post on your Facebook
timeline and a Facebook page. Let's imagine it: I have a Pinterest account with 4000 followers, a twitter account with 10000
followers, a Facebook account with 3500 friends and a Fb page with 4000 fans. That means my message/post will be shared
to a total number of 4000 + 10000 + 3500 + 4000 = 21500 people that have social relations with me! But I get even more:
because I obtain a Tire 1 link from Pinterest, a Tire 2 link from Twitter and two Tire 3 links from Facebook => I get a social
link pyramid. Wow...
Get niche bookmarking services
As important are niche blogs for related targeted keywords, the same importance have niche social bookmarks.
But what means niche social bookmarks? That means your link will be bookmarked on related groups/fan pages/boards.
Please retain that as more bigger are these landing pages (groups, boards, fan pages) as soon your link will get authority for
search engines. Also, another important detail is the number of fans/members.
