SEO analysis through Google Analytics

Now let’s see the main KPIs that I analyze through the personalized reports on Google Analytics and that I believe it is necessary to keep under control in any SEO campaign in order to understand the situation at a glance.

The concept of “Size”

Google Analytics is essential for analyzing web marketing campaigns, thanks to the large amount of metrics that it makes available to us for each dimension .

At the same time, however, orienting oneself among this amount of data could be rather difficult (from direct experience, even many professionals in addition to installing the monitoring code and setting some filters do not go further).

For this purpose, I believe that it is first of all important to clarify the concept of “dimension” in Google Analytics: a dimension is a characteristic of the visitor.

For example, a visitor who browses from Milan and who arrived on your site through an organic search on Google, will be registered with the following dimensions: city, keyword, source / medium.

For more information on dimensions and metrics, I refer you to the official guide .


The main KPIs for SEO analysis

KPIs are used internally by the SEO consultant to measure and optimize the performance of SEO services.

Mainly it is important to analyze three things:

  1. how the campaign has performed and is performing;
  2. from which channels users come and how they consume the contents;
  3. the level of active involvement of users with respect to the contents.

Internal KPIs to evaluate performance

  1. Sessions: indicates how much traffic has reached the website;
  2. Goal completions: indicates the total number of completed conversions (you can select a specific goal or divide the different goals);
  3. Revenue: indicates the revenue from transactions on the e-commerce site we are monitoring;
  4. Goal conversion rate: indicates the percentage of visits that translates into conversions;
  5. Ecommerce Conversion Rate: Indicates the percentage of visits that results in e-commerce transactions.

Internal KPIs to monitor content consumption

  1. Page views: Indicates how many times a page is displayed.
  2. Average time on page: indicates the average time users spend on a specific page or set of pages.
  3. Bounce Rate: Indicates how many users have limited themselves to viewing one page.

Internal KPIs to measure user engagement

  1. Pages / session: indicates how many pages are viewed on average during a session.
  2. Social actions: indicates which social action took place (e.g. +1, Like, Share)

These are the metrics you need to quickly and accurately monitor the performance of any SEO consultancy.

In order to group them together, it will be necessary to create a custom report that will have the Source / Medium dimension and those indicated as metrics.

Example of website and blog SEO analysis

For this example, the last 3 months were taken into account as the reference period and the following metrics were selected for the custom report:

  • Sessions;
  • Objective Completion;
  • Goal conversion rate;
  • Page views;
  • Average time on page;
  • Bounce Rate;
  • Pages / session;
  • Social actions.

As this is a simple corporate site, the metrics strictly related to e-commerce sites (Revenue and E-commerce Conversion Rate) have not been included.

Example of SEO analysis for e-commerce site

When it comes to SEO for e-commerce, you definitely want to know how revenue is quantified and what source / medium is generating it.

This example is also for the last three months and these metrics have been considered:

  • Sessions;
  • Revenue;
  • E-commerce conversion rate;
  • Page views;
  • Average time on page;
  • Bounce Rate;
  • Pages / session;
  • Social actions.
