You master something
when it becomes simple

In order to compete at a maximum level on SEM, setting the correct data design foundation is crucial to scale the accounts and provide accurate value to the rest of the paid and non-paid channels. MASK is a solid design methodology that deconstructs an account and builds a long-lasting structure that serves as a robust campaign "hardware". Gauss & Neumann believes that this is the single most important decision on SEM today. MASK is the result of nine years of research by Gauss & Neumann, and it has been recognized as a winning technique by first tier SEM investing companies and Fortune Magazine.

Just as architects create plans to design buildings, we think that the way you structure an SEM account really matters. We see keywords as possibilities of finding audiences that fit our clients' products. We transform regular accounts that range in the thousands of keywords and create new structures that range in the millions. The amount matters, but the design is even more important.

Gauss & Neumann splits any term that a user could use to find a product on a search engine, into the largest number of possible combinations of words that represent it. In average, our accounts are 8 times larger than most of the accounts in the SEM industry.

A Simple Idea: Most Possible Keywords

The simplest idea behind MASK is that it is so much bigger and better-organized than a regular structure, that it allows for a much deeper SEM optimization. Like the difference in precision between a 5x and a 40x microscope, MASK helps to find problems and detect new opportunities with much greater precision. This ultimately translates results into more sales at lower costs. Find out why

Click Through Rate (CTR)

Quality Score (QS)

Cost Per Click (CPC)

Cost Per Adquisition (CPA)

The problem with a regular SEM account is that by not creating all possible keywords, the search engine has to interpret the specific variations used by the user, and that comes literally at a price. The more control you have over the keywords in an account, the more control you have over the ads that get triggered by them, and that means better Click Through Rate (CTR).

Having a great CTR translates into a better Quality Score (QS) and the higher the QS, the lower the Cost Per Click (CPC) needed. In the end, this control over the keywords translates into a lower Cost Per Adquisition (CPA).

MASK is designed to take good care of your campaigns' QS health.

Besides the number of keywords, a MASK also takes good care of the structure in which those are allocated. A MASK could have multiple structures, depending on the type of business you have, and every single one is different. Creating a MASK for an sporting goods e-Commerce is not the same as a MASK for an airline. Every industry has different types of products and data that makes them different. A MASK architect takes into consideration most business variables for the clustering of keywords and labeling. This clustering is so strict that it allows for bidding models using semantic correlations and it is really easy to know where every single keyword is allocated.

Taking Control: Negative Filtering

Every SEM account contains a MASK and parallel to it, it also contains an anti-MASK of negative keywords. Because the clustering of keywords is so strict and does not have any impurities (misplacement of keywords), it is then possible to create a parallel structure that contains negative keywords in such a way that the MASK has total control over the advertising impressions. This second negative layer of keywords is impossible to create unless you use a MASK. This means that it is impossible to control the allocation of the impressions in every ad group without using this methodology.

Sometimes the impressions that should be controlled by an ad group are controlled by an adjacent one simply because of the lack of negative keywords in place. The anti-MASK is like a backbone that makes sure that we have total control over the impressions being made.

No matter the number of countries, languages and accounts you may have, MASK will allocate the same types of keywords in the same areas of the structure. This allows for product optimization across languages and countries. See below

An account in the United States with keywords like red t-shirts will be allocated in the same area as the keywords camisetas rojas in a spanish account. This helps having a view of the performance of one type of product, no matter the market or language.

In most companies, every account is disconnected from one another. But MASK allows for all types of cross-border optimizations. You could also zoom in into t-shirts of red color for men in M size across 20 countries at the same time without effort.

A MASK is like a really well organized warehouse in which you can easily find everything.

Tailored Technology

Along with MASK comes a great level of complexity that is only possible to optimize and understand with tailored technology. Our technologies are designed to make business decisions on millions of keywords and hundreds of thousands of ads every single day. These tailored technologies unify the data contained in all the structures with third and first party data, providing clarity and decision making.

Gauss & Neumann technologies include structure design, optimization and reporting.
No standard technologies are used or needed under our management.
More about tailored technology

When it comes to change the keywords bids, which is a great part of the SEM daily management, there are many software services out there that are able to take the historical data of a keyword and make decisions on whether to increase or decrease its CPC.

But what happens when the historical data gets split into thousands of pieces, in this case keywords? A regular management software does not have enough unitary data to make decisions and this is why then you should have a tailored bidding algorithm that groups the keywords that have similar behavior and makes a combined decision on what to do.

Grouping keywords in order to take a decision is made possible because of MASK that allows you to find where every keyword is, and where the similar keywords are.

MASK is a systemic way of managing SEM accounts that allows for a great level of optimization but also for geographical and SKU expansion. With MASK, improvements in Cost Per Acquisition (CPA) averaging 30% and increases in sales volume of around 40% are possible. These variables will depend on the market and industry of operation.

In the end, MASKs™ becomes a reflection of the market and compete organically with other players whose structures are smaller, stiffer and unstructured. With MASK, everything translates into more sales and profit margin.
