The safest way to buy links discretely is one by one directly from webmasters or
bloggers. These would be near impossible to trace for a search engine unless they
were clearly labeled in a sponsors category. This is also the most time-intensive
way to buy links and maybe the most expensive. However, it can be a very
worthwhile endeavor as you have the most control of who is posting your link, what
it says, and whether a search engine will be able to detect it as a paid link and
ignore it.
If you do want to buy links directly, you will need to identify sites that are worth
the effort of contacting individual webmasters or bloggers. These sites should have
a high PR value and original content. They should not be too obvious about the paid
links that are sponsoring them, as that might cause search engines to blacklist the
entire blog. You should try not to be lumped in a grouping of links or a links page
as this can affect your backlink credit and trigger the search engine to ignore your
link. You should be able to ask for the anchor text that you want and the placement
of your choice (within reasons).
Keep in mind that just because you are willing to buy a link directly from a blogger
or website doesn’t mean they have to sell it to you. Many bloggers follow some ethical guidelines and might have trouble taking links from profitable sellers of
payday loans or subprime lending, based on principle alone. Don’t take offense if
that reason comes up. This is part of doing business on the WWW, where the rules
of business become more independently managed and at the discretion of the
owner of the site. Instead, see if you can offer the webmaster or site owner some
compromise that will help you get your link while keeping their principles intact.
