Rule-based AdWords bidding: Hazardous loops

Published by Joni on March 30, 2017

1. Introduction In rule-based bidding, you want to sometimes have step-backs where you first adjust your bid based on a given condition, and then adjust it back after the condition has passed. An example. An use case would be to decrease bids for weekend, and increase back to normal level for weekdays. However, defining the step-back rate is not done…

Hakukoneoptimointi toimittajan näkökulmasta

Hakukoneoptimointi toimittajan näkökulmasta

Published by Joni on March 30, 2017

Johdanto Media on riippuvainen mainostuloista. On jatkuva kiistelyn aihe, miten paljon toimittajien tulisi kirjoittaa juttuja, jotka saavat klikkejä ja näyttöjä suhteessa juttuihin, joiden yhteiskunnallinen merkitys on korkea. Nämä kaksi kun eivät aina kulje käsi kädessä. Sosiaalisen median ja hakukoneiden merkitys toimittajan työssä Käytännössä toimittajat joutuvat työnsä puolesta huomioimaan juttujen kiinnostavuuden sosiaalisessa mediassa. Tämä on tärkeää vaikka haluaisi kirjoittaa vain yhteiskunnallisesti…

Affinity analysis in political social media marketing – the missing link

Published by Joni on March 30, 2017

Introduction. Hm… I’ve figured out how to execute successful political marketing campaign on social media [1], but one link is missing still.

Koneoppimisen jämähtämisongelma

Published by Joni on March 30, 2017

Konekin voi joskus jäätyä. Kone oppii kuten ihminen: empiirisen havaintoaineiston (= datan) perusteella. Tästä syystä samoin kuin ihmisen on hankala oppia pois huonoista tavoista ja asenteista (ennakkoluulot, stereotypiat), on koneen vaikea oppia nopeasti pois virheellisestä tulkinnasta. Kysymys ei ole poisoppimisesta, mikä lienee monessa tapauksessa mahdotonta, vaan uuden oppimisesta, niin että vanhat muistirakenteet (= mallin ominaisuudet) korvataan tehokkaasti uusilla. Tehokkaasti, koska…

In 2016, Facebook bypassed Google in ads. Here’s why.

Published by Joni on March 30, 2017

Introduction The gone 2016 was the first year I thought Facebook ends up beating Google in the ad race, despite the fact Google still dominates in revenue ($67Bn vs. $17Bn in 2015). I’ll explain why.

Buying and selling complement bundles: When individual selling maximizes profit

Published by Joni on March 30, 2017

Introduction When we were young, me and my brother used to buy and sell game consoles on Huuto.net (local eBay) and on various gamer discussion forums (Konsolifin BBS, for example). We didn’t have much money, so this was a great way to earn some cash — plus it taught us some useful business lessons along the years. What we would…
