SEO Question: I was thinking about buying a link exchange software product. I was looking at ___________ and ___________ and wanted to know what one is the best?
SEO Answer: I think Arelis can be decent for harvesting email information, but many sloppy webmasters screw that up by using too much automation. You really need to try to connect to a webmaster, and since each site and each person has different motives anything that is automated or generated is crap.
For example, I recently got this gem of an email:
I'm an editor of a website ______ about watches. I looked through your site http://www.threadwatch.org and I think that it is very interesting. I have an offer for you. I'd like to send you a few of interesting, cognitive articles with unique content about structures and machinery of watches, which will be written by a group of authors. If interested, feel free to contact me. I appreciate your opinion.
Thank you in advance.
Sincerely yours, Anastasia
Notice that they didn't specifically mention link exchange, but they wanted to put link laden content on my site that was unrelated to my site.
Most of the software designed for automation leaves footprints if it generates pages, and / or is crap for other reasons.
And while it may seem like the watch example above is a rare one many authoritative sites tend to rank for terms that are a bit random in nature. For example, Matt Cutts ranks at #173 for Bacon in Google right now. If you fired off emails to the top 200 bacon resources sure enough one of those spam emails would hit Google's search quality / web spam evaluation leader, and obviously that is not a good thing.
The links that you really want do not exist on generic will-exchange-with-anyone link pages. Most of those pages are not designed for humans and are likely rather easy for most sophisticated search engines to detect.
I think pretty lowly of most link exchange networks as well.
Automation works well for some people, but if you are new to the market you probably are not going to figure out how and what to automate until you have a bit of experience. As a general rule of thumb I never automate any human interaction and avoid using software that leaves footprints, especially if that software is typically primarily used by people who aim to game search relevancy.
If you are in a competitive marketplace with a new site and the only links you can get are ones that you have to request then you eventually are going to need to mix up your methods, especially as your market becomes more hyper saturated.
