Search Algorithms
Google ranking systems sort through hundreds of millions of webpages in the Search index to give you useful and relevant results in a fraction of a second. These ranking systems are made up of a series of algorithms that analyze what it is you are looking for and what information to return to you. And as we’ve evolved Search to make it more useful, we’ve refined our algorithms to assess your searches and the results in finer detail to make our services work better for you.
Here are some of the ways Google uses Search algorithms to return useful information from the web:
-
Analyzing your words
-
Matching your search
-
Ranking useful pages
-
Considering context
-
Returning the best results

What is ReTargeting and How Does it Work?
Retargeting, also known as remarketing, is a form of online advertising that can help you keep your brand in front of bounced traffic after they leave your website. For most websites, only 2% of web traffic converts on the first visit. Retargeting is a tool designed to help companies reach the 98% of users who don’t convert right away.
How Does ReTargeting Work?
Retargeting is a cookie-based technology that uses simple JavaScript code to anonymously ‘follow’ your audience all over the Web.
Here’s how it works: you place a small, unobtrusive piece of code on your website (this code is sometimes referred to as a pixel). The code, or pixel, is unnoticeable to your site visitors and won’t affect your site’s performance. Every time a new visitor comes to your site, the code drops an anonymous browser cookie. Later, when your cookied visitors browse the Web, the cookie will let your re-targeting provider know when to serve ads, ensuring that your ads are served to only to people who have previously visited your site.
Re targeting is so effective because it focuses your advertising spend on people who are already familiar with your brand and have recently demonstrated interest. That’s why most marketers who use it see a higher ROI than from most other digital channels.
When Does ReTargeting Work?
Retargeting is a powerful branding and conversion optimization tool, but it works best if it’s part of a larger digital strategy.
Retargeting works best in conjunction with inbound and outbound marketing or demand generation. Strategies involving content marketing, AdWords, and targeted display are great for driving traffic, but they don’t help with conversion optimization. Conversely, retargeting can help increase conversions, but it can’t drive people to your site. Your best chance of success is using one or more tools to drive traffic and retargeting to get the most out of that traffic.
