The software listed  here spams websites. When used right it can become an invaluable tool for increasing traffic drastically, but you have to use it wisely, unless you want to fuck things up and drop out of serps.

Xrumer.

An extremely powerful link building tool. It spams forums, guest books, comments on blogs, it’s extendable and it can be “trained” to do whatever you want. It bypasses captchas, registers accounts. Pure awesomeness. Although it has a steep learning curve. A parsing tool “Hrefer” is also included, for making your own databases of forums, guestbooks, blogs etc.

Some Xrumer features:

• Multithreaded submitting: over 50 simultaneously running threads possible! (30 threads are recommended for optimal performance under 128 Kbps bandwidth)
• Software can perform registration at forums (if necessary for posting messages) and automatically fill in the required fields. Upon successful registration XRumer posts the user-specified message and/or links.
• The powerful built-in proxy-server checking script locates available proxy-servers worldwide, choosing anonymous addresses among them.
• Software is able to work with lots of different types of forums and guestbooks: phpBB and PHP-Nuke with any modifications, yaBB, VBulletin, Invision Power Board, IconBoard, UltimateBB, exBB, phorum.org, wiki, different types of bulletin boards and even custom-written code.
• Attention: unique feature – software works around EVERY possible type of protection from automatic registration, including:
  - Pictocode protection (tickets, captcha), which look something like: "Enter the number you see in the box".
  - E-mail activation protection.
  - Java-script protection.
• During the process of posting a detailed log is created with precise path-links to posted messages so that you can check every link and every posted message afterwards.
• A variations system, using which you can post up to 10000 messages all looking different but with similar contextual meaning and the user-defined hyperlinks in them. It helps to broaden the key queries (for Search Engine optimization) and protect your posts from being filtered out by Search Engines (that is, your posts will be included in SERPs).
• If the forum has more than one category, the software chooses the one most suitable for the message, otherwise it sends the message to off-top, flame sections or the like, and in case those do not exist – to the most visited category on the forum.
• BB-code can be used.
• The following forum base processing tools are included: repeated links deletion, hit descending sort, service denial according to customizable black list, and various filters.

PROS:

• Great speed
• Flexibility
• Outstanding results, when used right.
• Href parser. Very powerful.

CONS:

• You need a really powerful server, lots of proxy servers etc etc (not exactly cons, but whatever, it’s just that good)
• Tough learning curve. You might need some time to learn how to use this software.

PRICE: The current cost of this software is 540 USD.

Website: LFE

PROS:

• Moneyback guarantee.
• Customer support
• Great features and functionality.
• Built in site parser.

CONS:

• Pretty hard to find not spammed sites. But it’s still very good.
• No trial version

The key is to build or buy a good base (And remember, no one really sells a good base, for obvious reasons) of websites that aren’t spammed like hell (ever seen guest-books, like, refresh the page and 20 new links appear?). Links from sites like that can do more harm then good. So getting a good base of websites is crucial for good results. This can’t be applied to SEnuke, and the list of supported engines in LFE is pretty limited. But both of them are pretty noob friendly and easy to master. Xrumer, on other hand is virtually capable of spamming any site you want. But it will take you some time and probably programming knowledge to accomplish these tasks. A simple example of usage: create profiles at niche forums, with links to your website. Make a post from each of the profiles. Links and probably some traffic gained. All automated. Can you imagine how much time it would take you to manually do this? Just don’t forget to spin anchors, titles and content to avoid Google’s filters.
