How To Get Sandboxed By Google
Most webmasters and SEO experts want to get higher rankings for their websites (or their client's websites). To do that, they have to know how to get sandboxed by Google so that they can avoid being sucked down into a search engine black hole.
The best way to get banned from Google is to buy links. It's amazing that companies like TextLinkBrokers still exist. This company tells you to put code on your website to automate the link buying process. Their code will automatically insert links into your website's content and keep track of where those links are.
That's just a dumb idea for any number of reasons. The most obvious being that Google can easily detect paid links this way, and you set yourself up to be pounded by the algorithm once you're found out. The company defends its position by saying that "well, everyone does it." That's not a great defense.
Companies like J.C. Penny have been taken down over paid links without the use of automated scripts. Don't think that Google won't come after you because you're "small potatoes." That's precisely why it comes after you. It's easier to make an example out of a nobody. Plus, no one's going to miss you in the search engines if you're small. The authority sites can afford to plea bargain for reentry into the search results.
Stuff Keywords Into Invisible Text
Websites still do this, and it's amazing. Google has said, on numerous occasions, that stuffing keywords on your site is a "no-no." Making the keywords invisible by making the text the same color as the background of your site is even worse. Some website designers think they're being clever by using CSS to shift the keywords off page. These keywords are still hard-coded into the webpage, but users can't see them. The problem is that search engines can see them and Google is smart enough to know what's going on with text that's moved off-page. The result? You earn yourself a big fat penalty.
Some webmasters are scared to death to "leak" PageRank from their site. They are operating under the mistaken assumption that linking out to other sites somehow hurts the site linking out. Don't be one of those misguided webmasters.
Google loves it when you're social. It loves it when you link out to relevant sites. Likewise, it loves it when you have relevant sites linking back to you. What Google doesn't like is when you have irrelevant sites linking to you and vise versa. Are you a website focused on plumbing? Why do you link out to a website about making money online? Don't do that. Link to home improvement sites or sites devoted to plumbing tools or even sites devoted to homeowners flood insurance.
If you want to drop in the rankings, just create duplicate content. You won't get an official penalty, but you might hurt your website's rankings if Google thinks the duplicate content was posted before the original content. If you want to write content, make sure each article starts on a blank canvas. No rewriting. No article spinning. It's harder that way, but it's better.
