This is an amazingly complex subject that has many many answers but I am going to list a few things that I have tested over the years.

Duplicate Content

This seems like a no brainer but people do it alot. I personally have copied free reprintable articles and posted them on my site and ultimately got banned. At the time I couldn't understand why my site got banned for doing it but the 50-100 other sites with the same exact article was on their sites and they were ranking fine? So I got to checking those sites out and found that they had alot of unique content on their pages that made their article look alot different from the other websites with the same exact articles.

So I found that there is a duplicate content filter that calculates the percentage of the pages on the web for duplicate content. So make your content at least 25%-50% unique. I suggest rewriting articles in your own words so that it is completely unique and you will do good all the time.

This also goes for affiliate products and content. Don't just copy and paste products to your site. Take a little time and write your own description for the products you put on your sites. It will pay off big for you in the long run when all the other affiliate sites are banned or ranking poorly and yours is not.

Too Many Keywords

Another problem I had with a website I built was using the main keyword of the page too many times. If my page was about "Gifts" I had links to pages about "Baby Gifts" and "Gifts for Him" "Gifts for Her" ...... I don't want my blog to get banned so I hope you get the point. But I had the keyword "Gifts" over and over in almost every link on the page. Well that is a Red Flag NO NO! My site got instantly banned.

I did find a way around this problem by simply taking the main keyword out of every link and only linking with "For Him" and "For Her" etc... I also made sure I wasn't using my main keyword too much on the page text too. I use a 2-4% keyword density.

Using Automated Queries to Google

One time I found a free script that I reverse engeneered to automatically grab Google's Daily Top 100 Query List. This got my site banned completely within about a week. That little screw up got my site an actual visit from a google employee! I know because I seen them visit my site when I was looking at my live visitor stats. A day later the site completely disappeared from the google results.

That one taught me a lesson! Google is not joking around when they say "Don't use automated queries to google". I also believe that doing too many "site:yoursite.com" queries will get you banned too but I can't back that one up by facts.

Deleting Pages

One time I deleted about 15 useless pages from a site of mine and a week later my rankings tanked for about 2 months in google which wasn't a complete ban but google must have gotten confused and didn't know what to do? I cannot prove that my site tanked because I deleted those pages but it definately made me think that.

Creating Too Many Pages Too Fast

 I like to do things the easy way and I am sure there are millions just like me. So I created a script that automatically created thousands of pages instantly pulling different content from various affiliate programs like amazon.com and others. The site was brand new and I traded a few links and had an instant new mega site that I didn't have to do anything to. Google happily spidered the entire site and within a week I was seeing traffic coming to it and I was making money!After about a month it was banned completely! I couldn't figure it out at first but then I figured it out. Too many pages too fast is a NoNo!

I eventually figured out how to automatically build the mega site slowly so google would not ban it. The answer was to put noindex,nofollow metatags on the newly created pages so that when google spiders the new pages that have never been crawled or visited googlebot would see the noindex,nofollow meta tag and stop spidering at that page making the site look like it doesn't have much content yet. Then the next time googlebot spidered the page it would have the index,follow meta tag making it look like the site has grown a little sinse the last visit.

So be very careful when you build huge mega affiliate sites using automated scripts. If you build it they will come! But it you build it too fast you're banned.

Buying Links On High Page Rank Sites

I still can't believe that google bans sites for buying links on other sites because I think links are what makes the web go round. But I did have a website that was about 2 years old and ranking well and doing fine. Then one day I found a site selling links from a PR6 page for $20 for one year! I couldn't pass it up! I had to have it! Within a month that site was completely banned from google.

Unbelieveable Google! Seriously? What is so wrong with buying links? If I can afford to buy a link for a site then that link should be worth more to google than a link that I traded with a site? If I think a site is good enough to actually pay someone to link to it then that link should be worth a vote for my site? Am I right people?

 I think we should support a new up and coming search engine like Vmgo.com Search Engine. It is a really awesome search engine! It is smart and fast and has video results and actually learns from you when you search. It is webmaster friendly too!
