Following last year's pillage of general web directories, Google reset the PageRank on many article syndication directories to PR3 or PR0. EzineArticles did not get edited, perhaps because they have more stringent editorial guidelines, they were a known market leader, or they were a Google case study. Just about every other article syndication directory did.

About 3 years ago I create a directory of directories so I could keep track of new directories. But very few of the directory owners considered editorial quality. Eventually they started polluting their directories with site-wide links to payday loan websites.

On the paid side some people who had success creating one low quality directory decided to create a dozen more pay for inclusion websites, often cross promoting them with discounts...after you buy one they thank you and offer you the ability to buy inclusion in the other dozen at half price.

And on the cheap end, it got to the point where lots of companies like Directory Maximizer do directory submissions for a dime to a quarter each, allowing you to space out the submissions, mix anchor text, and mix listing descriptions. And while many of these services claim to be "SEO friendly" and offer services in bulk, you can see that a search engineer might not hold the same opinion. :)

By the time a technique is cheaply and reliably outsourced the value has already been diminished or will soon become worthless.

• lower cost and automation means more people will use the technique
• the lower cost often appeals to those making lower quality websites
• the more people who use a technique the more likely it is for search engineers to kill it

Andy Hagans used to charge $900 for doing a couple dozen article submissions, and back when he did it, it was probably worth it. He marketed it to highbrow clients who used it to promote quality website. Lower end webmasters probably could not justify paying $900 for that service.

And you could get a hand rolled product of similar quality to what Andy charged $900 for, but at a price $870 cheaper from We Submit Articles. About a month after I showed Andy that We Submit Articles website, where someone was selling services similar to his for $30, he changed his model to promote linkbait stuff, moving himself up the value chain, creating something that is much harder and more expensive to replicate.

Article submission software and article remixing software came out, only making the issue worse. Andy probably could have continued his old model for another year and been fine, but he knew that Google would eventually pull the rug out from under it. It took a while, but the article directories had their PageRank edited.

Search engineers can't stop everything, but by the time a technique is cheaply and reliably outsourced the value has already been diminished or will soon become worthless.

• lower cost and automation means more people will use the technique
• the lower cost often appeals to those making lower quality websites
• the more people who use a technique the more likely it is for search engineers to kill it

When you think of the web from that perspective it is easy to see why my current business model is so much better than the old model. The community interaction allows for deeper understanding, and helps people move past using just the techniques that are quick, cheap, and easy.

Parasitic hosts and upload sites, social media sites full of spam, endless cross-referencing internal tagging, blog carnivals...all are quick, cheap, and easy. What do you think is the next quick, cheap, and easy marketing technique that Google will kill?
