Attribution model - the weighted number of conversions - GA
-
Hi,
1.Can someone explain me with an example what is "The weighted number of conversions under the custom selected attribution model"? How Analytics calculate it?
2. If I increase e.g social source for 1.4 in my attribution model, my organic or direct source are loosing that weighted number of conversions. Could it be because of organic or direct getting lower credit, or for some other reason?

Thank you.
But, hm, I don't know. I'm using a data driven attribution model with 12 channels.
If I increase boost for 1.4, my boost weighted conversions will grow from 8 to 8.50.
How can I see, how much real conversions I will get with that change?

Hey Tormar,
I saw that you posted this question a few times here in various Google Analytics forums, but didn't get any help. Let's see if we can't get you all sorted out.
Your questions as I understand it
- You want an example to better help you understand 'weighted number of conversions' under the custom selected attribution model within Google Analytic's Model Comparison Tool.
- You want to know how Google Analytics calculates this value.
- You want to know if when you increase the value of social sources in your attribution model, why you then see a lower value for organic or direct.
I'm going to attempt to tackle these three, but if you feel I did not adequately understand your question, please feel free to add more information or correct me.
Before we get started
I think it's important to first address that all attribution models within Google Analytic's Model Comparison Tool are a zero-sum game. By that I mean that there is an inverse correlation between each facet of each individual attribution model.
Stated differently, each conversion (or goal, or transaction, etc.) is only one conversion. While the linear attribution model disperses the 'value' of a conversion equally across all interactions, the summation of all of these interaction's value will always = 1.Ok, now that we've covered that let's jump into it.
- I think you're attempting to create a custom attribution model. When doing so, you will need to first determine what existing model you want to base your custom model from, then you will define the value you want to give to each facet. I cannot possibly go into all the possible combinations here, but here's a starting point to diving into the process.
The weight you're giving each facet is the percentage (expressed in decimal form) of the total (which is 1) that facet will receive. In a linear attribution model with 5 interactions each interaction would receive 20% (0.2) of the credit for each conversion.
Circling back to your question, the number of conversions when viewing a report is the summation of all attributed values across the defined timeline & parameters. - I explained this a bit in #1, but Google Analytics is taking your defined values for each facet & distributing value aross them proportionally to the values you defined in the custom attribution model.
- As I mentioned above, this is a zero-sum game, or an inverse correlation. When you increase one facet's value (in your example, social) the other values must decrease proportionally.
I hope this helps. Let me know if you need any further help or if this answered your question!
Regards,
Trenton

Any possibility to track goal completions/conversions at a sub-page (non-landing page) level in Google Analytics?
We’re promoting our sub-page it's http://www.flightcentre.ca/flights/london on our homepage under the slideshow so I need to see how many people went to the homepage, then went to this page, and then converted (enquired or booked.) What I can’t see is how many people did that. I know how to look up how many people landed on that page and then converted, but I need to know how many people navigated there and then converted. Is that possible? I can only see Goal Completions if I look at that page as a landing page, but that only presents a very slim view of the total visits when compared to those pages generally. Any way to check the entire behavior or activities happening through this page i.e. /flights/london?

When to determine that a change DIDN'T affect conversion rates
Hi everyone, Description of test: We're a lead gen site trying to add more value by providing users with real, live quotes after they submit a lead. However, we don't want showing the quotes to tank our lead conversion rates. So we're running a test where 50% of leads see quote results and 50% don't, and we compare the lead conversion rates for each. The best possible outcome is to show that showing the quotes DIDN'T negatively affect conversion rates. My issue: When do we conclude the test? In the end, we're hoping to see that the change didn't cause a statistically significant difference between the control and version B, which is the opposite of every other test I've ever run. So, at what point do we conclude that the changes in version B didn't have a significant effect on lead conversions? Currently the control is doing 5% better than the variation with a p-value of .379

Increase conversion rate to buy
I am trying to understand why my women fashion site has a very low conversion, basically zero apart from some occasional sales (last one a few months ago) There is a lack of organic traffic the to shop subdomain, but what worries me is that (email/social media) campaigns to existing clients who happily buy repeatedly from our brick and mortar store do not generate results, despite using promotion codes etc. Before investing heavily in PPC campaigns etc, I'd like to improve conversion. Any advice on what can be improved ? PD: link can be found in my profile.

Ideas on multi layered conversion opportunities
I was speaking with an SEO and he brought up multilayered conversion opportunities - means of capturing a users info dependent on the point in the purchase process they are. The two examples he used were a user who just wants to download a brochure to "window shop" and a user who is ready to buy and wants to get a price. Just curious if anyone had any additional ideas for means of conversion other than the 2 above and any additional thoughts or ideas on the matter.

Conversion Rate Optimization (CRO): Best Approach/Plan Documentation
Hey Mozzers - First off, I am well aware of what CRO is, its benefits, and why it is essential for any inbound or performance marketing campaigns. However i am a total newbie at the actual planning and implementation of CRO, so any advice/feedback on the questions below are much appreciated! When planning a CRO experiment/test what is the best way to document it? Should i develop the full plan ahead of time laying out each element? If so, what elements should i include in this plan? What are the KPIs i should report on? What tools should i use for reporting (i was thinking a blend of Google and Clicktale)? Any lessons learned through out your campaigns? Thank you all so much for your input! Regards - Kyle

Weeding out irrelevant analytical data to see truer conversion rates
Here is the scenario. We have many brick and mortar store locations as well as an ecommerce website. It's hard to get exact, but my estimates seem to be that approximately 1/3 of the visitors to our website are interested only in obtaining information about the brick and mortar store locations and not interested in ecommerce transactions. Of course this kills the conversion rate. We use google analytics and I'd like to somehow be able to quantify with more accuracy what the "real" conversion rate might be. Is there some method to weed out specific pages/traffic (like brick and mortar landing pages) from being taken into account when conv. rate is calculated? The number that matters for conv. rate of course is "visits" and not unique pageviews, so I'm not sure that really would do anything helpful. Any tips?
