Text Link Advertising is becoming a much more popular method for sites to earn that extra bit of cash. In particular, this form of advertising is perfect for blogs!
However, personally I do NOT use link brokers either to buy links or to sell links!
There has been a lot of talk about the problems and dangers of selling and buying text links, if you are new to text link advertising then have a read of some of these sources:
Selling text links, not worth the hassle?
Text Link advertising overview
I have chosen not to link to any articles that claim that text link ads are dangerous, will get you banned, will cause you to lose the ability to pass pagerank, will harm your rankings etc… simply because I don’t want to seem biased.
However, my personal opinion on the matter is that you are better off doing link trades with other related sites instead!
If your site is under PR6 then you are unlikely to make more than $50 per month from selling text links. In one of the above links the site owner was offered $70 per month for a sitewide link from his PR7 site. So you really have to ask yourself, do you want to make an extra $70 per month and risk being penalised by Google? Or would you be better off using your link power to do high quality link trades with relevant sites and therefore GAIN instead of LEAK pagerank, and you should easily be able to make at least $70 extra per month from the traffic that those link trades bring in.
I will summarise even further:
PAGERANK 6 BLOG:
SELLING TEXT LINKS ADVANTAGES
*Extra $70 per month
*Could get banned
*Could lose the ability to pass PR from your site
*Inner pages could stop passing PR
*You could lose some of your current PR
*You are leaking link juice
*If you link to an industry other than your own then you are linking to NON-RELEVANT sites (Read about HUBS for more info on why this is vital)
*You could be using that space to do relevant link trades with authority sites. Therefore you are losing out on new traffic sources
I am sure there are many people who will disagree with my opinion on this, but I feel that high quality sites have very little to gain and a LOT to lose by selling links. Therefore it is only the low quality sites that should benefit from selling links.
So everytime someone tells me their site sells text links I instantly de-value the site.
