### Post-Test Questionnaire Results  
Immediately after the completion of the experiment, the post-test questionnaire was filled in so that the participants could recall all related information. In the first phase, we had recognition questions, in which all of the advertisements on the site were displayed to see which ones were noticed and to what extent participants were influenced by them. In the second phase, we examined the degree of annoyance with other forms of advertisements that did not exist on the experiment's website. This information would further help us in the broader research. Table 3 depicts the data collected when users were asked to rank the online ad techniques based on the degree of annoyance (1: Not annoying at all, 5: Extremely annoying). It is evident that the most annoying advertisement was the modal popup advertisement, with 72.5% of the users (37 users) placing it in this position. Following immediately were the intraconent with content reorganization ads, deemed annoying by 13.7% (7 users). The right rail and nonmodal techniques were considered less annoying, by 49% (25 users) and 23.5%of users (12 users), respectively. Initially, we had the right rail advertising technique, which was located on the right side of the page and could not be closed. Among the participants, 80.4% (41 people) noticed the advertisement during their navigation on the website; 34.1%, with 14 valid responses answered \"1-Not annoying at all\" for this specific type of advertisement; 31.7% with 13 valid responses answered \"2-Slightly annoying\"; 19.5% with 8 valid responses answered \"3-Annoying\", meaning it annoyed them to a more neutral degree; 12.2% with 5 valid responses answered \"4-Very annoying\"; and just 2.4% with 1 valid response found this advertisement \"5-Extremely annoying\". The overall conclusion from the above results for the right rail advertisement was positive, as the majority of the participants did not find this form annoying or were only mildly annoyed. \begin{table}

Table 2: User Sample. For the nonmodal technique, 72.5% of the users (37 people) noticed this particular advertisement, which also appeared on the right side of the page, had a smaller size than the previous one, and could be closed if the user wished. Of the sample, 23.7% with 9 valid responses answered \"1-Not annoying at all\" to the question \"How annoying did you find this advertisement?\"; 39.5% with 15 valid responses answered \"2-Slightly annoying\", 28.9% with 10 valid responses said \"3-Annoying\", and 7.9% with 3 valid responses said \"4-Very annoying\". None of the participants found this advertisement extremely annoying. The overall conclusion from the above results for the nonmodal advertisement was positive, as the majority of the participants were only mildly annoyed or did not find this form annoying. The modal technique was noticed by all participants, with 51 valid responses.
