Now Google is the largest and most popular search engine in the world. We are so found of google that if we want to search anything on the internet we don’t say search anymore we say ‘just google it’. If you see Google is a website with URL “” with a search bar only. Whenever a new website, blog, image, video, etc is uploaded on the internet(world-wide-web) Google index that website and make a directory of it in its server. So, next time when a user searches for a similar article via Google. It shows the results from its directory which in the end leads the user to correct article or website.

The search engine hot or spider bot crawls on the world-wide-web and look for the new publicly available websites and fetch the information from them.

What are the goals of SEO?

The main goal of search engine optimization is to improve the discoverability of your own website in search engines by means of good ranking positions on relevant search queries(keywords). Other goals of SEO are to improve the appearance of the snippet which consists of meta title and meta description and thus a better click-through rate and more visitors. Another goal is to improve the expectation compliance for visitors who come across content from search engines.

What are the key SEO metrics / KPIs?

Possible SEO metrics or KPI’s are:

  1. Visibility indices that refer to a keyword-relevant to the business model.
  2. Snippet click rates or CTRsBounce rates.
  3. Duration of stay
  4. Ranking position distribution per SERP

  6. Individual keyword ranking positions.
  7. ….

There are some tools as well which can help in getting the right SEO metrics. Especially all visibility indices such as tools such as Sistrix, Searchmetrics or XOVI are rightly criticized.

Differentiation between Tactical SEO & Strategic Search Engine Optimization.

SEO mainly works on two levels.


  1. Strategic Search Engine Optimization.
  2. Tactical search engine optimization.

At the tactical level, content optimization, technical optimization for crawling and indexing control, duplicate content avoidance, and snippet optimization are performed.

On a strategic level, the aim is to create a digital entity for Google in the form of the website and, in addition, to improve the entity relevance and thus the authority of the domain.

While previously search engine optimization was rather tactical, after the introduction of the Knowledge Graph, the Hummingbird algorithm, the panda and penguin updates, strategic search engine optimization has clearly gained priority.

In modern search engine optimization, there are the following task domains:

  1. Technical search engine optimization
  2. Optimization of the navigation/information structure or the internal linking
  3. Improving user behavior
  4. Content production and optimization
  5. Offpage Optimization
  6. Search Pattern Optimization

Not all of these SEO tasks can be clearly assigned to tactical or strategic search engine optimization in a differentiated manner. For example, link building can be both strategic and tactical. However, the main goal of link building in the form of entity formation and authority improvement remains a strategic goal. Thus, the focus of link building is on strategic SEO. Content can also be distinguished between tactical content marketing and strategic content marketing, as explained in detail in the article Difference between Content Marketing Campaign & Content Marketing Strategy.

Technical SEO

This is a very crucial part of SEO. You need to make sure you improve your skills, especially in this area. For every SEO expert or SEO company, this skill is a must. Technical optimization is a typical task area for tactical search engine optimization.

Technical SEO is used to optimize technical errors on the website. Here are some of the most common technical errors:

  • Duplicate or missing description tags
  • Images without alt tags
