The SEO (Search Engine Optimization) articles mostly all say that organic growth of links is best. If your website is new, you would not have any backlinks and certainly not have any deep links The benefits of increasing your links is that all the major search engines rank your site based on complex algorithms that include the quantity and quality of your backlinks.
In the early 90s, we searched the internet by browsing folders on the mainframes of various university computers. Then Tim Berners-Lee’s grand idea of the web caught on: a standard way of finding and linking to documents stored on any computer server hooked to the internet. Early search engines used links as the sole way to index the web, making algorithms easy to manipulate: the page with the most links got the top listing. Then search algorithms became more sophisticated. They learned analyze the text on our page, interpreting which words and phrases were most likely to be significant: the key words.
For years, search engines did this mechanically: they put extra weight on tags (until people gamed the system) and repeated words (until people gamed the system) and exact-phrase-match URLs (until… oh, you get the picture). Every time people figured out what signals search engines were using, clumsy SEOafs would overuse them, until search engines jettisoned that signal from algorithms and found a better one. Some pundits predicted that one day, SEO would die.
They missed the profound and powerful shift that had happened right under our noses. Once search engines began to use more signals than simply hard-coded links, they were no longer dependent on humans to tell them which pages or concepts linked to what. They were now making connections all by themselves, based on words, discovering connections we might never discover. In other words, our words have become organic links, and search engines are building the synapses of a world-wide artificial intelligence based on that verbal web. This is exciting!
Also, not all kinds of writing are suited to web searches. People search the web for specific things: answers, gifts, directions, favorite persons/shows/books/sports/etc. They do not tend to use search engines to look up opinions, observations, abstract discussions, creative writing or entertainment. Instead, they find those things through word of mouth, personal recommendation, social media: a Facebook share by a friend, or an interesting-looking Tweet. People who write on those kinds of topics (or write articles like this one) cannot usually get much search engine traffic; they need to master the art of social promotion instead.
There’s numerous tutorials out there designed to find the right keywords. The basic principle is to brainstorm your topic (note: YOUR topic; you must have something to say) using a tool like Google’s keywords tool to discover what people are searching for that’s related to your topic. This is a time to be creative and playful. Brainstorm. Play with language. It’s an interaction between you, with your own words and terms and ideas, and other people’s words and terms and ideas.
