Google Analytics Tracking Cookies

Cookies are small text data given to a web browser by a web server. The data is stored on a website visitors’ hard drive and is returned to the specific web server each time the browser requests a page from that server.

Cookies are used by web servers to remember information from page to page and visit to visit, and can contain information such as user preferences, shopping cart contents, the identifier for session Ids, and can know whether users have logged in and do not need to authenticate again as they navigate through the site.

Google Analytics uses cookies to differentiate one user from another and to pass information from page to page during a single user's web session. The cookies help GA collect data about a given browser, along with the information requested and sent by the visitor. Cookies do not identify people, but rather they are defined themselves by a combination of a computer, a user account, and a browser.

Google Analytics uses only first-party cookies as opposed to third-party cookies. This means that all cookies set by Google Analytics for your website domain send data only to your server. This means that the data cannot be altered or retrieved by any third party server.
Google Analytics uses cookies to obtain the following data in order to generate reports on your website traffic.

• Determining Visitor Session
• Identifying Unique Visitors
• Tracking Traffic Sources
• Customizing Tracking
• Utilizing Google Website Optimizer

Google Analytics' JavaScript code is compatible with your website's existing cookie usage. All Google Analytics cookie names begin with _utm to prevent any naming conflicts between their cookies and your web server’s. Google Analytics sets a combination of persistent and temporary (__utmc) cookies on visitors’ machines.

__utma, This cookie lasts for 2 years from setup/update and is typically written to the browser upon the first visit to your site from that web browser. The purpose of this cookie is to determine unique visitors to your site and it is updated with each page view.

__utmb, This cookie lasts for 30 minutes from setup/update and is used to establish and continue a user session with your site.

__utmc, This cookie operates in conjunction with the __utmb cookie to determine whether to establish a new session for the user or not. This cookie does not have an expiration date. It expires as soon as the user exits the browser.

__utmz, This cookie lasts 180 days from setup/update and stores the type of referral used by the visitor to reach your website. This cookie is used to identify whether the visitor has reached the site via a direct method, a referring site, a search engine, or a campaign such as a text ad, banner ad or an email campaign. A __utmz cookie contains domain hash, timestamp, session number, campaign numbercould look like: utmz=181178431.1117767825.1.2.

utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=seo

__utmv, This cookie lasts for 2 years from setup/update and is used to create a custom user segment (e.g., paid vs. non-paid visitors). This cookie is optional and will be set only if the setVar method is called.

__utmx, This cookie lasts for 2 years from setup/update and is used by Website Optimizer and only set when the Google Website Optimizer (GWO) tracking code is installed.

Understanding how Google Analytics uses cookies helps with setting up more customized and advanced settings.

Google Analytics – a Consultant Needed?

I have previously written some articles on Web Analytics on topics such as Web Analytics & Cookies, Introduction of Google Analytics, improvement of website usability utilizing Web Analytics, SEO KPIs, Branding KPIs, and benefits of Web Analytics.

Given the growing importance of web measurement and the fact that the aforementioned articles seem to be some of the most popular posts on my blog, I decided to focus on writing some more tactical posts on setting up and implementing Google Analytics.

If you have a small and static website, setting up Google Analytics can be very easy and straight forward and you may not need a Web Analytics consultant especially if you are relatively tech savvy. A little bit of training on GA and you are good to go. However, if your site is complex, dynamic, offers e-commerce transactions or you need to measure traffic across multiple domains, sub-domains or third party shopping carts, you might need the help from a Google Analytics consultant.

Before you choose Google Analytics as your Web Analytics application of choice, you may consider some of the features GA has to offer:

Language – Google Analytics interface currently supports over 24 languages.

Scalability – Google Analytics can support both small and large sites. However, there are some limitations in terms of number of goals you can set (currently limited to 4 goals per profile). In addition, in cases of high traffic websites, some of GA stats are shown based on data sampling.

Even though Google Analytics has made web analytics affordable for small businesses, GA also offers some sophisticated features helpful to enterprise level websites.

Integration with Google AdWords – in just few steps you can easily integrate your Google AdWords PPC campaign with your Google Analytics and start measuring your AdWords pay-per-click campaign performance without the need to tag every single keyword, ad copy, ad group an campaign.

Campaign Reporting – whether you would like to measure your Google AdWords performance, your PPC campaign on Yahoo or MSN adCenter, e-mail marketing, web advertising, your social media initiative or offline marketing campaigns, Google Analytics can.

Funnel Visualization – if your audience need to path a funnel to become a lead or customer, you need to monitor and optimize your funnel on an ongoing basis to increase your conversion rate. GA’s funnel visualization report just does that.

Customizable Dashboard – if you need a quick overview of some of the most important key performance indicators, you can set your dashboard up so that you can have a bird’s eye view of your site performance in a glance.

Cross-Segmentation – Google Analytics allows you segment your traffic by different criteria and compare the performance of different segments.

Measuring PDFs and Virtual Page Views – Google Analytics allows you to measure how many times your PDF files are being downloaded by creating virtual pageview and track back the downloads to the contributing campaigns.

Event Tracking – In some cases, you may need to track certain events and actions to see how your audience interact with your interactive elements of your site such as videos and flash files. GA makes this easy for you through its event tracking feature.

Internal Site Search Reporting – this is one of the most useful yet least utilized feature of Google Analytics. Internal site search reports give you insight into the mind of your audience and can help you optimize your website usability and product offerings.

Automated Reporting – Too busy to remember to login and check your website performance? Set up, schedule and share reports automatically.

I will try to cover some of these features as well as some more advanced Google Analytics set up techniques in the feature posts.

SES 2009 - Search Engine Strategies Conference

Time flies...June is around the corner and so is Toronto SES 2009. It is as if it was just yesterday, I attended SMX Search Analytics Toronto and exhibited at Toronto Search Engine Strategies Conference back in 2008.

We will be again exhibiting at 2009 SES event which will be held at Sheraton Centre Toronto Hotel. This year’s SES conferences will be held on June 8th and June 9th. In addition, on June 10th, there will be some SEM and SEO training programs (more on SEM SEO Training).

I am so excited about this year’s SES conference. At a time of recession, more and more marketers are concerned about their marketing dollars. Search Engine Strategies is a great opportunity for marketers to learn more about the power of Search Engine Marketing and Search Engine Optimization.

If search marketing campaigns are executed properly they can prove to be one of the most effective channels for marketers.

I will post more updates on the 2009 SES Toronto.

Google Profiles – People Search Improvement or Social Media Supremacy?

Google announced earlier that by enhancing Google Profiles they give people a greater control over their online profiles when somebody searches for their names on search engines. Google has already started showing Google profile results at the bottom of US search queries for people names.

Currently only 4 profiles are shown for name-query searches. These results provide snippets from user-generated Google profiles and link to the profile pages. From your Google profile you can link to your blog, LinkedIn profile, or Twitter account. Currently the links are not using nofollow. However, that might change as spammers might start building bogus accounts just for the sake of link building.

By providing links to your other sites from your Google Profile, you can help Google better build a Social Graph of you on the Internet. Google can potentially use this data to better understand the relationship between sites, decide how to flow PageRank, and further personalize search results.

As Google Profiles evolves, Google will add more functionality to the product which will provide Google with more insight into people`s social connections.

Even the Google Profiles are currently shown at the bottom of the SERPs, they could potentially rank on top of the search engine results pages which could potentially divert the traffic from major social media sites such as LinkedIn and Twitter providing Google with more real estate/platform for socio-demographic advertising.

SMX Search Analytics – Toronto

After Danny Sullivan and Chris Sherman departed from Search Engine Strategies (SES) conference and expo series, initiated SMX Search Marketing Expo. SMX brings together some of the sharpest minds in the search engine marketing industry.

Earlier in April, I attended Toronto SMX Search Analytics Conference and Expo. The purpose of Search Analytics is to provide marketers with insight into their visitors, customers and those who bounced away. The promise of the event is to equip advanced search marketers with tools, tactics and strategies that can maximize the effectiveness of their search engine marketing campaigns.

Toronto SMX Search Analytics conference kicked off by keynote speaker, Venessa Fox and covered topics such as:

• Analyzing & Converting Organic Search Traffic – Covering SEO KPIs
• Analyzing & Converting Paid Search Traffic – Utilizing Web Analytics to measure PPC campaigns
• Up Close with Google Analytics – Measuring traffic utilizing GA
• Top Ten Customized Search Analytics Reports – Creating Custom Executive Dashboards
• Successful Testing for Improved Search Marketing ROI – A/B and Multivariate Testing
• Traffic Segmentation & Why It Matters – segmenting organic and paid search traffic by location, demographic and psychographics to improve ROI
• Search Analytics & Competitive Intelligence – Analyzing competitors’ strategies and bit them at their own game
• Creating a Data-Driven Culture – Building an Analytics and data driven culture in the organization
  

The two-day Toronto SMX Search Analytics program was jam-pack of information. While SES Toronto is a great source of information for marketers interested in Search Engine Marketing, SMX series are more suitable for more seasoned search marketers.
