Why can’t the search engines figure out my site without SEO help? The Recommended Google Adsense
Search engines are always working towards improving their technology to crawl the web more deeply and return increasingly relevant results to users. However, there is and will always be a limit to how search engines can operate. Whereas the right moves can net you thousands of visitors and attention, the wrong moves can hide or bury your site deep in the search results where visibility is minimal. In addition to making content available to search engines, SEO can also help boost rankings, so that content that has been found will be placed where searchers will more readily see it. The online environment is becoming increasingly competitive and those companies who perform SEO will have a decided advantage in visitors and customers.

If you are serious about improving search traffic and are unfamiliar with SEO, I recommend reading this guide front-to-back. There’s a printable MS Word version for those who’d prefer, and dozens of linked-to resources on other sites and pages that are worthy of your attention. Although this guide is long, I’ve attempted to remain faithful to Mr. Strunk’s famous quote:
“A sentence should contain no unnecessary words, a paragraph no unnecessary sentences, for the same reason that a drawing should have no unnecessary lines and a machine no unnecessary parts.”
Every section and topic in this report is critical to understanding the best known and most effective practices of search engine optimization.
How Search Engines Operate
Search engines have a short list of critical operations that allows them to provide relevant web results when searchers use their system to find information.
1. Crawling the Web
Search engines run automated programs, called “bots” or “spiders” that use the hyperlink structure of the web to “crawl” the pages and documents that make up the World Wide Web. Estimates are that of the approximately 20 billion existing pages, search engines have crawled between 8 and 10 billion.
2. Indexing Documents
Once a page has been crawled, it’s contents can be “indexed” – stored in a giant database of documents that makes up a search engine’s “index”. This index needs to be tightly managed, so that requests which must search and sort billions of documents can be completed in fractions of a second.
3. Processing Queries
When a request for information comes into the search engine (hundreds of millions do each day), the engine retrieves from its index all the document that match the query. A match is determined if the terms or phrase is found on the page in the manner specified by the user. For example, a search for car and driver magazine at Google returns 8.25 million results, but a search for the same phrase in quotes (“car and driver magazine”) returns only 166 thousand results. In the first system, commonly called “Findall” mode, Google returned all documents which had the terms “car” “driver” and “magazine” (they ignore the term “and” because it’s not useful to narrowing the results), while in the second search, only those pages with the exact phrase “car and driver magazine” were returned. Other advanced operators (Google has a list of 11) can change which results a search engine will consider a match for a given query.
4. Ranking Results
Once the search engine has determined which results are a match for the query, the engine’s algorithm (a mathematical equation commonly used for sorting) runs calculations on each of the results to determine which is most relevant to the given query. They sort these on the results pages in order from most relevant to least so that users can make a choice about which to select.
Although a search engine’s operations are not particularly lengthy, systems like Google, Yahoo!, AskJeeves and MSN are among the most complex, processing-intensive computers in the world, managing millions of calculations each second and funneling demands for information to an enormous group of users.
