Ok! Now, we can go see the ins and outs of Google Ads in greater detail. In a different article, we delve into what it takes to build a great AdWords campaign structure.

Google Ads: King of Inbound Marketing

Thus, since Google Ads is mainly text ads appearing on top of the search results when we look for anything, Google Ads is considered to be an inbound channel - the most important of them all. We explain below what inbound marketing means.

Google Ads is considered the most effective inbound marketing channel.

Inbound marketing is when the user is looking for our product or service and is a main trait of digital marketing. Outbound marketing, on the other hand, is when we are looking for the prospective customer and do so by sending letters, postcards or advertising in social media channels.

Inbound marketing channels, in most cases, yield a greater return on investment than outbound marketing channels.

In another article titled ‘How to advertise on Google’ we delve into why AdWords is the best marketing channel for small businesses. In this article, we tackle what is Google AdWords and how it works.

Starts by... the user looking for something

Since text ads are by mar the most popular in Google Ads, let's focus on them and see how they work.

Someone looks for something in Google...anything

In AdWords is all about the search query. The Google user types what s/he is looking for - whether buy something, look for directions or the latest video of La Macarena. The advertiser creates a list of terms for which s/he is willing to have an ad copy displayed and whose clic will originate a cost - the so-called cost per click.

Most often, the search terms an advertiser bids on signal purchase intent and start by the word buy and/or similar wordings.

A typical keyword a retail apparel business would likely bid on would be buy fashion shoes nearby me for instance.

The advertiser comes up with a list of terms. When somebody writes them in Google, the ad copy can show up and upon being clicked, generates a cost.

Followed by... Google launches its algorithm to find a match

Google matches the search query with the keywords present in the AdWords’ advertiser keyword pool. If a match is found, Google will run an algorithm aimed at determining relavance and quality, also known as the keyword quality score, alongside the bid placed by the advertiser.

Since there is only room for up to four adverts on top of the search results and up to two below them, the algorithm will determine which 6 keywords have the highest quality score. AdWords will then place their corresponding text ads in the search results page accordingly.

Then... this someone has options

The user has now an option - or better yet, up to 17 options, 17 results in the first page for her/his search query. 4 ads on the very top, followed by 10 organic results followed by up to three additional text ads on the bottom of the search results page. If Google deems the search query to have local intent, a map with up to three local results will be placed in between the top ads and the ten organic results.

Although no official percentages have been disclosed, it is estimated that up to 20% of all Google users click on the text ads, 35% do so on the local results whenever present, and the remaining 45% click on one of the organic results.

Given how competive are many industries, ranking in one of the ten organic results is many times a lengthy and ardous process. Google AdWords -the 4 text ads on top of the results- provides for an immediate solution since the text ad can rank on top of them as soon as the campaigns are created.

The more thought you put into writting a great ad copy, the more clicks it will get which translates into a lower cost per click overtime.

Finally... this someone visits the website and gets to buy

When a user clicks on an ad, s/he is redirected to the advertiser’s website and is now a potential lead who can buy the product or service the advertiser has to offer.

When this happens, and if the cost of the clicks that take for a user to buy is less than the product’s price tag minus the margin, the advertiser has a positive return on the investment (ROI).

To sum up, Google Ads makes for an excellent channel to drive more traffic and aquire more users for all companies, big and small.
