Understanding How Google SEO Algorithm Works

google-searchHave you ever wondered how Google’s SEO algorithms work? Algorithms are computer programs that look for clues to give you back exactly what you want. Assume you perform a web search on any topic, say lawn care  specialists in Fredericksburg, thousands, if not millions of web pages with useful information appear. Algorithms are the computer formulas and processes that take your search questions and turn these questions into answers. Today, the Google’s algorithms depend on more than 200 unique signals or clues that make it possible for experts to guess what one might be looking for. These clues include factors such as freshness of content, terms on websites, your region and PageRank.

In this article, we share insights gleaned from a large-scale statistical analysis of local search engine ranking factors in Google.

How Search Works

Search happens billions of times a day in the blink of an eye. There are many components of search processes and the search result pages. Search engines have two main purposes; Crawling and building an index, and providing search users with a ranked list of websites they have determined are the most relevant.

Finding Information by Crawling

Google use software known as “web crawlers” to discover publicly available web pages. Crawlers look at web pages and follow links on those pages. The crawlers go from link to link and bring data about the web pages back to the Google’s servers. Crawlers visit websites and look for links to other pages to visit. The software pays particular attention to new sites, changes to existing sites and dead links. As a website owner, you don’t need to set up restriction for crawling and indexing so that their pages can appear on search pages. Site owners can choose how content is indexed on a page-by-page basis.

Organizing Search Information by Indexing

rankingThe web can be compared to an ever-growing public library with billions of information, pages, and books. Google gathers these pages during the crawling process and then makes an index. When you search at the most basic level, the Google algorithms looks up at your search terms in the index and finds the appropriate pages. After this level, the search becomes more complicated. When you search for a word like “cats,” you probably do not want a page with the word “cat” on it hundred times. You probably want to see pictures, videos and a list of cat breed. Google then looks at a list of factors including when the page was published, if the page contains pictures, videos and much more.

How to Avoid Spam Content

Every day, millions of irrelevant spam pages get created. Google fights spam through a combination of computer algorithms and manual reviews. Spam pages attempt to gain to the top of search results through techniques such as repeating keywords over and over, putting invisible text on the screen and buying links that pass page ranks. Spamming makes sites for legitimate owners to be buried and become harder to find. Google algorithms can detect spam and demote these pages automatically. To rank on top of search results, only avoid spam.

Here are examples of spam site owners should avoid;

  • Cloaking and sneaky redirects
  • Hacked sites
  • Hidden texts and keyword stuffing
  • Parked domains
  • Spammy free hosts and dynamic DNS providers
  • Thin content that has little or no added value
  • User-generated spam
  • Unnatural link to a site
  • Unnatural link from a site

seoWhile the Google algorithms address the vast majority of these spams, their team also address spam manually and prevent it from affecting the quality of your results. Under the policy conventions, Google cares deeply about information that you find on the net. They strive to make information available except for narrowly defined cases such as spam, legal requirements, malware and preventing identity theft.

Final Word

Understanding how Google works is crucial to understanding how to ensure your page ranks as high as possible in search engine results. Ensure that you avoid top mistakes that prevent the effective crawling process to take place. If Google spiders can’t reach your server, you won’t get indexed. Avoid incorrect URL parameters as they can result in pages from your site getting dropped from the index. Avoid poorly written title or meta tags. If you are a blogger, use the relevant SEO plugins to help you with your meta tags. If your site has not adhered to proper search engine optimization to improve your page rank, you won’t often be crawled. Be guided by the Google Webmaster Guidelines that define best practices on that webmasters need to follow.
