Same Bio and Link in Multiple Networks

Hi, Im registering my website in about 300 networks (video, social, bookmarking, blogs, picture, business, news, etc). I including in all username, profile pic, website and bio.

The question I have is: Do i have a risk using in all the networks the same website link and bio? the bio includes the link of the website and a set of keywords.

How would you recomend me to do it to help with seo and dont risk anything? this site is what you guys would call my "money site" so I need to protect it at all cost. In the other hand Im also very interested in registering my username in all networks before someone else does.

My site offers a service, doesn't sell have any ads and doesn't do any blackhat seo

Thank you for your help!

Can anybody please help?

i am doing something similar for ages about my products and services and don't have a problem so far..

well, i am not registering at 300 sites, but probably 100 tops as i register only to quality ones and ones i think will bring me clients and exposure

the sites you mention are probably trustworthy and high authority so having links on all of them is not a problem..

if you are too paranoid about it, simply use url shortener for your links..

IMO - You are fine. Manual real link building would do the same.

Make sure these things though.
Content on website and keyword are relative. Make a post or page about the keyword you are going after. Use unique content on all the 300 - sounds like Tier 1 links. Make sure you also do a Tier 2 which aims at your Tier 1 links.

Example. Each layer is a tier.

www.moneysite dot com / blog post keyword driven

1. All Tier 1 Links point up to this site and post (interchange them) i.e. - web 2.0 like wordpress, weebly etc. youtube video embedded in them - all one keyword

2. All Tier 2 point up to the links created with a few randomly to your site.

3. All Tier 3 point to Tier 2 with a few randomly to Tier 1

4. A little BH - Xrumer Blast towards all Tier 3 and randomly to Tier 1 and 2 (never your money site)

Read around on the forum - look under (on left hand side toolbar) main forums, link building and read those.

Also Cash 202 wrote a post labeled SEO blueprint.

Kimi has a great one as well.

You are on the right track but remember there are a lot of theories - judge on results!

GOOD LUCK!
