Billions of adult-themed searches every year are why no publicly owned search corporation can stay in business without monetizing those search streams as well.

Putting the right keywords into the right places in your pages and site, then building keyword-rich links from authority sites to each of your pages is the essence of search engine optimization. The links between a site's internal pages can also improve a site's position in the search engines.

Search engines analyze and follow links to determine how to rank any page or site. Higher link quality is always more important, and easier to achieve, then sheer link quantity.

Hub Pages is an authority site because it has a very large content base that's being added to and updated all the time. This is also factored into your hubscore, along with how much traffic you bring in from outside the hubpages community.

Google loves freshly updated content and tends to check back often on those sites. Hubpages content frequently ranks well in the search engines as well as providing quality links to other pages you wish to index. This hub debuted in Google at #29 for the search phrase sex and the search industry, its title, in less than 35 hours, with absolutely no other promotional linking.

Another consideration in writing this article is the lively debate within the hubpages community concerning the use of words like sex and sexy in titles which wouldn't really be expected to contain those words. Not only is this practice inappropriate, say some, but it degrades the quality of writing and can even cost hubpages its page rank authority status with Google. Before researching this hub, I tended to agree.

We're going to research the highly searched for keyword porn to show that Google's mission is to organize all of the world's information, including adult themes. This means that those sites get indexed, ranked, and rankings, just like any other site.

After verifying that it gets significant traffic, we'll use G's free tools to see if it costs AdWords advertisers enough to make it worth targeting for AdSense revenue. This process will also give us a sizeable list of topics to write related pages about. This synonym list will also help you with keyword density and readability.

Warning: this is not for the faint of heart or the Bleached White Hat SEO crowd.

These exercises using Google's own free tools are going to expose you to sexually specific search terms that you may have never known Google would rank a site for or sell PPC ads on.

Should you choose to proceed, there is an excellant chance that you will be shocked and disgusted by some of the terms that Google and WordTracker are going to show you on a list of 100 keyword variations.

Every serious webmaster reaches a point where he or she needs to get a realistic idea of what gets searched for. This information is critical to any successful product selection and marketing plan that will bring in enough precisely targeted traffic to make enough money to justify the long, steep, and expensive learning curve that so many encounter when they begin wondering about how to make money online.

Searching for variations of the phrases traffic, web traffic, and web metrics are of little use. A phrase like sex and the search industry, however, will clarify that with a number of sites on the first page showing that the sex industry has over 25% of the search traffic. Seriously. This does not include gambling, by the way. My guess is that those 2 terms combined get around 45% of all searches, so any other metrics are skewed by not including these fields.

Google's Webmaster Guidelines are only guidelines. The only hard and fast rule is determined by their algorithm, which they can change as often as they wish. Last I heard, Google had 35 data centers and used multiple caches. This makes it possible for them to change a page's ranking once a week or once an hour with no real effort if that's what they think they need to do to keep the game honest. This also makes buying expensive downloadable e-books a waste of time and money. The only way to get and stay curent in the SEO field is to focus on the basics of content and links.

Search Engine Optimization is a misnomer in my opinion. Once you know about filters such as allintitle:url and allinurl:url you'll likely agree that one's SEO skills are how many filters they can use in the search engines to get one page of supremely relevant information.

Google can't do this on its own- it would be like telling your grandmother a joke using a currently popular double or triple entender. What may seem simple and obvious to us can be foreign to many English-speaking people, even within the same country.

This means that the better you know the wants, needs, fears, vernacular, and hangouts of your target audience, the better your results in the search engines will be. You'll get higher rankings with less effort while spending less for promotion.

https://adwords.google.com/select/KeywordTool is where you go to get Google's opinion of what keywords and search phrases it expects to find in that context. This is helpful as a way to write more naturally than using the same keyword every paragraph all the way through a long web page. By clicking the Website content box near the lower left corner, you can have it look a site or page over and tell you what it thinks that site is about and its keywords. This is going to get really interesting in a moment.

Let's back up just a moment and google the term porn. Notice in the top right corner that Google sees around 237,000,000 porn sites. All ten sites listed on the first page are indexed and have links to sites that Google thinks are very similar. (!) Seems to fly in the face of everything we've been told by Google, the gurus, and the forums, right? Well this search just proved that G really does index and rank sites for terms that we wouldn't expect them to unless we had already tried finding something in that realm.

Think Mark Knowles was kidding when he wrote that G knows your sexual preferences? Think again if you've ever searched along those lines. Your only privacy online is what you don't search for. Think about it. This is deep.

Now let's restrict the search somewhat by trying allintitle:porn to come up with 17,100,000 results. This is very important, since the title meta tag is the first place you insert your keyword or search phrase for on-site optimization. You can shout it out by including it in your url, which we find by using the allinurl filter like this:

Allinurl:porn to come up with 5,640,000 sites. Notice that the order we applied these filters thinned the herd by determining who is really serious about ranking for any given keyword or search phrase. It goes almost without saying that anybody who's put their key term(s) in their url is also going to have it in their title. Placing your keywords in those key meta tags, plus using CSS stylesheets to place your keyword close to the top of the page drastically improves your placement. Remember, any web page is presented to the computer as a serial file, which means that the closer a keyword is to the top of the page, the quicker it is for a search engine spider to begin figuring out what the page is about.

Another way to help out is to use several divs and name them using your main and secondary search terms. Want to see this in action? Simply do a search for West Michigan SEO and you'll see that it's #1 while it's more about a township issue than SEO. Still, it outranks a slew of "serious" SEO types, yuk, yuk, yuk.

That's right, only ten short years ago G was not the tail wagging the dog. It was sandboxed and fighting for its life against the likes of Yahoo, Lycos, AOL, and a slew of others. How they got to be top dog is well worth studying in detail because it shows how corporations with large budgets can create an overwhelming presence. Microsoft is another readily visible example.

Over the last 10 years or so the search engine game has changed radically and often. An entire industry sprang into being which was concerned with getting sites to the top of the search engines, who would change the rules, initiating another cycle, ad nauseum. The end result is so much outright out-dated and contrary material on the web that not even the dime a gross gurus agree on what works, but they'll sell you "the answer" for a measly $77.

What works is the same as it's always been: provide your reader with information that is relevant to what they're really searching for, not just what terms they're typing into the search boxes. This is called targeting the intent to buy, and, in my opinion, is the sweet spot unless your intent is to monetized using a chain of attention scheme to spoon-feed the information in bite-sized chunks across several pages which present advertising or offers of some sort. A chain such as this is an excellent way to create your own nano web which targets several hundred keyphrase variations.

So much for theory and philosophy and all the heavy junk. What we want to know is how much G charges for a keyword so we can tell how the best way to use it is. Our next free Google tool is https://adwords.google.com/select/main. Here's the real shocker- for 38 to 46 cents a click we can get 1,900 to 2,400 clicks per day targeting the highly competitive keywords porn and sex. They predict we can do this for anywhere from $470 to $1,000 per day. This surprised me, since it looks too cheap, so if G pays out 40% as your cut, you're only getting 15 to 18 cents per click. Even if you could snag 600 of those visitors every day, that's probably going to make you less than $1 a day in adsense revenue.

This is why there's terms like "Black Hat" SEO and enough people using fully automatic site makers that place adsense ads on pages scraped (copied) from all over the web. This is why you're always being asked "Are you Human?" and straining to read the security code to keep using that site. What's going to be interesting one of these days is for somebody to figure out how much of the web is real and how much has been scraped once, twice, thrice...

http://freekeywords.wordtracker.com/ is the industry standard for this. They monitor a small percentage of actual traffic and multiply to get a guesstimate of how many searches will be performed that day. They also have a box you can click to remove "offensive" results, which I would guess is adult material of any interpretation. The drop down box will let you select remove dubious, adult only, or even turn off the filter. Let's click Adult Only and type in porn.

Now we're on to something. Even at the bottom of that list in the 100^th least popular porn term is a term that is guesstimated to get 1,966 searches per day. And the list will turn the stomach of even the most stalwart porn fan because of its seemingly all-inclusive nature.

We've just taken a brief look at the human condition. Using the tools in this hub for a few more cycles to refine search terms can be a telling sociological toolbox. A phrase that's beginning to come into the global consciousness is global consciousness. Unless you've spent some serious research time in the behavioral targeting and trend predicting areas, this is a new concept to you. What it means is that by carefully planning and executing a search engine marketing campaign, you can place an idea or product in the way of an incredible ground swell of search traffic that you rank #1 for. Since it only takes one link from an indexed site, you can invent your own search term and popularize it for surprisingly little time and money.

The commonly accepted notions about the search engines not handling "offensive" or "adult" topics have been categorically debunked. This is not license to go out and target those markets, simply a look at how things really are, as opposed to how things are normally presented to us. It goes almost without saying that anybody ranking well in these bad neighborhoods does not think in normally accepted social and moral ways, so this hub has not even begun to scratch the surface of competing for those terms. They are reputed to lead the Internet Marketing industry's tools and tactics by several years, and are known places to get drive-by viruses in your computer, just as you would expect to need protection when visiting this environment off-line. Buyer beware probably sprang from this environment.
