The trading or bartering of links between two related sites. "If you put my link on your homepage, I will put your link on mine". To this day, still very effective, but....

Google caught on.

Google decided this was good. Lot's of good sites linking to each other BUT, this link schema isn't quite as good as if site A, linked to site B, without site B linking back, so Google 'DEVALUED' links, not 'PENALIZED' them.

People caught on.

Now people are buying links to their sites from any other sites that have high pr. Thus giving them a one way link and a PR transfer. Not a bad idea, but...

Google caught on.

Google is thinking, "Now why in world would this quality PR8 web hosting site have a text link to this PR2 Viagra site? Pretty easy answer huh? So Google 'DEVALUED' this type of link.

People caught on.

Now people are buying RELATED links on RELATED sites. This is good!

Personally I see nothing wrong with this, and I don't think Google does either. This is called 'Advertising', and it is a common, normal, honest form of advertising and marketing for your site. If you look back to very beginning of internet, and first example I gave you, this is almost identical. The only difference is that back then, most people linked to you for free, today, you have to pay.

Does that make all of other link building techniques worthless? NOT AT ALL! It just means those types of links aren't as valuable, so it will just take more of them to create same effect.

Well, I am hoping you see my point here? I could go on forever on this subject. The main point is that webmasters need to understand difference between something being 'DEVALUED', and something being 'PENALIZED'.

Being penalized for something is when you are doing something bad, wrong, illegal, or immoral.

Being devalued, just means that topic in question is being saturated, and is no longer rare or unique. In order to keep competition and honesty, there needs to be a new and better means developed to maintain an edge.

So next time your site drops in rankings at Google, before you scream 'Penalty', make sure that Google just didn't tweak their algo to devalue your technique.

And SEO specialists know that search engines love new content, above everything else.

2) Create a Solid Website Structure

While search engine spiders can maneuver your website like a human being can't, they too are fond of websites with good structures and easy-to-find content. Most CMS software can automatically create menus and navigation from categories that you set. Once you create a new category or subcategory, you can instantly publish it on all your pages, with click of a button.

According to popular SEO wisdom, search engines spiders do not index pages more than 3-4 levels deep on your website structure. In response to this, some CMS software also allows you to put all your content on first level, for example "http://www.yoursite.com/article236.html'. However, using CMS' control panel, you will still be able to see all content within their respective folders and subcategories.

3) Search Engine Friendly Capabilities

This is perhaps most significant development in Content Management Systems. As more businesspeople and SEO begin to dig deep into CMS, need for spider-friendly pages has taken center stage. Recent advancements have enabled CMS users to install modules (sometimes already built in) to make it appealing to search engines. The latest CMS software can create keyword rich pages, titles, meta tags and even anchor text.

That, coupled with advanced search engine spiders being able to go deep into databases to index pages, is set to turn Content Management Systems into next big organic SEO tool. In fact, search engine friendly CMS even makes organic SEO specialists, sad to say, sort of 'obsolete'.
