##Initial approach: why this research?
At [Ninetailed](https://ninetailed.io) our main purpose is to improve the user experience and help other companies with it. We are also web performance junkies and are obsessed with persistently improving our service performance in the region of milliseconds.

As marketeers, developers and product managers we abuse the usage of tag managers and third-party scripts. Using external scripts has a data value, but also an adverse consequence: poorer web performance.

###Our hypothesis
Our hypothesis is that developers care more about web performance than other digital roles like marketeers and that they consider third-party scripts as an issue for the performance of their websites.

###We believe that
We believe that awareness around third-party scripts performance and the impact on the user experience is the first step for multidisciplinary teams to develop optimization strategies.

##Results
At the date of the analysis, the survey has 185 answers after promoting it to developers, product managers and marketeers in our professional network and in different Facebook, LinkedIn and Slack groups.

###Participants
####Roles
Most of the participants are developers (51%), followed by marketeers (21%) and product managers (12%).

The survey has participants from SMB and also corporations with more than 500 employees. Most of participants work in companies up to 50 employees (70%).

###The answers
The main questions of the survey ask how much do the participants agree with a statement. The responses are based on [Likert Scale](https://en.wikipedia.org/wiki/Likert_scale), from “Strongly disagree” (score 1) to “Strongly agree” (score 5).

The survey questions are:

* Web performance has a positive impact on the user experience.
* Web performance has a positive impact on SEO.
* Third-party scripts harm website performance.
* Ad Blockers harm website analytics.
* Ad Blockers are an issue for me.

The participants strongly agree that performance plays a major role in a good user experience (avg. 4,6) and benefits SEO (avg. 4,5). Most of the respondents agree that third-party scripts are an issue (avg. 4,1). Regarding Ad Blockers, the respondents are neutral, and do not agree nor disagree if Ad Blockers affect their analytics or if they are an issue for them.

Analyzing the responses based on the role we see some minor differences.

The three groups agree that performance has a positive impact in UX and SEO. They also agree that external scripts harm web performance. Marketeers agree most that Ad Blockers harm the website analytics, compared to developers which are neutral and product managers that disagree.

####Frameworks and Tag Managers
Finally, 49% of the respondents use a Tag Manager. 62% use a CMS, 22% a Single Page Application and 5% a static site or static site generator.

##Conclusions
Not only developers care about performance. The main digital roles which are responsible for a website strongly agree that performance has a positive impact on the user experience and SEO. They also agree that third-party scripts harm the performance and are neutral about Ad Blockers and the impact on website analytics.

Even if there is awareness about performance, the usage of external scripts [grows every year](https://httparchive.org/reports/state-of-javascript?start=2016_09_01&end=latest&view=list). Without more details, we cannot say if this is based on a cost-benefit analysis or the data-needs to optimize the user experience and business goals.

For future surveys we should explore the solutions and efforts put into improving performance and the reasons behind a neutral position towards the impact of Ad Blockers in website analytics and the data-based decision process.
