Buying Profile Backlinks - Are They Worth?

It helps more than not having them at all, I suppose.

But you'll need several thousand of them (at least) to give you the "backlinking weight" of one blog comment + backlink on a context-relevant higher-PR page of a decent site. Opinions will differ, but to me, they're a waste of time and money.

That's a good and valid point, but it's the second-stage worry here. The first-stage worry is that many of them may turn out to be in defunct or semi-defunct forums and never be indexed at all!

I don't believe this one, myself. It were as easy as that to get "sandboxed", people in subfusc-headwear forums/sites would be a promoting it as a service to "get your competition sandboxed".

Buying dofollow profile links for page Google PR improvement -- We can't
be 100% sure of results if we don't have access to the search engine
ranking algorithm and heuristics used by Google... Some say it works for
them in this regard, some say it doesn't, so your tests will show you if it
works for you or not... Google only says links with the dofollow tag
instruct their bots to share the Google PR juice of the page to the linked
page...

Buying dofollow profile links to improve the search engine rankings of your
pages for your target keywords -- See above...

Buying dofollow or nofollow profile links to increase targeted traffic -- If
accounts with those profiles are:

...in community sites offering content and promoting discussions relevant
to your onsite content and whatever you're offering,
...in online communities with pages ranking high for your target keywords
on popular search engines,
...in online communities where people interested in topics and sub topics
covered by your target keywords and whatever you're offering frequently
hang out, and
... have contributed useful information and advice in those online
communities for years and have steadily built a good, solid reputation as
an expert source of information, advice and content relevant to the
content and discussions in those online communities as well as to your
onsite content and whatever you're offering ---

The test results I constantly study show this has been working for my
clients, though we don't buy accounts... I implement workflow processes and training methodologies to have a group of employees building the
reputation of new accounts as a friendly expert source of useful content,
information and advice in heavily trafficked online communities relevant to
the target keywords, topics, sub topics, audience and whatever my
clients are offering on their sites and as products or services...

Profile Backlinks helps getting good rank in Google.

You may use Paul and Angela Backlinks packets. Do it about 3 to 6 month. Definitely you will see the result.

Google like dofollow link. Paul and Angela Backlinks packets provides dofollow links.

I have been runing a test- I ran a large amount of profile links to a site -I check the site rank before and after - Ranking before: 16 in Google, after Number 1 - thats enough evidence for me!

You aren't going to be sandboxed from profile links lol. Google won't find them all right away, and it will take more work for you to get them indexed than anything. What is the point of 10,000 profile links, when 100 show up. lol.
