I am looking for an excel expert who has a lot of experience with PPC data. I will need you to pull data from adwords campaigns and make quantitative decisions based on the data. For your first project I will need you to compare organic vs paid traffic results I have a brand keyword adwords campaign running and client is concerned that they are paying for PPC when organic ALONE would be okay. We must use the current data to prove to them that PPC + Organic has a higher revenue in sales for them. Please describe to me in your proposal how you would achieve this? Ill give you a hint: https://www.dropbox.com/s/meuul2qpop5v718/Mario%20Example.xlsx?dl=0 IMPORTANT: Make sure to answer the question I asked above. Tell me how you would prove to the client that PPC Branded + Organic together is higher revenue than Organic Alone.

We are looking to build lists of businesses that sell digital goods / services online to use for our outbound sales activity. Our target businesses have very specific attributes. They must be online merchants which sell digital goods and services and accept payments, and do not sell physical goods only. We believe that finding and documenting the technical attributes of identified target websites may give us a way to filter and create lists of leads for new outbound campaigns. Target Company Profile: We are looking for a list of companies that sell digital goods & services (non-physical goods) on a global scale through their [Company’s] own website. These companies all accept online payments in exchange for these digital goods / services. Please see the follow list of verticals as an example of some businesses that sell digital goods & services Task: The task is split into 2 phases. Phase 2 is dependent on the successful completion of phase 1. Phase 1 Identify technical attributes that are common for the following list of domains.(e.g Web server, Email Services, SSL Certs, Host providers, Content Management Systems, Payment Service Providers, Frameworks, Advertising, Analytics, Widgets, Certain text). These common attributes cannot be present in the following list of websites, whose businesses, while similar, do not fit the target criteria spelled out above. Some exceptions to this may be permitted however any resulting list should be 80% accurate or above. Identify the combination and order in which the attributes need to be applied to allow filtration of a given list of websites and identify the expected accuracy of the operation. A larger sample set of a typical list can be supplied as part of the contract. Phase 2 The second part of the contract is dependent on the successful completion of steps 1 and 2. If an accuracy ratio of 80% can be demonstrated to be reached by using this process, refine a list of target websites as supplied by us. We aim to create a refined list of 30,000 web addresses.

I have a probability (6P4 and 8P4) ad Latin square (http://statpages.info/latinsq.html) problem. For a Latin square of 4 digits, it is 1 2 4 3 2 3 1 4 3 4 2 1 4 1 3 2 each number appear in each ordering position once and precede and follow by each number once. I would like something similar to be done for 1,2,3,4,5,6 In 6P4, there are 360 combinations, but I need to reduce it to a latin square of 4 digits so only 4 of them can appear in the sequence, so for example, 1 should be precede and followed by null,2,3,4,5,6 only once in each of the 4 number sequence. I only need the Latin Square answer patterns for 6P4 and 8P4. Please quote the price and the time required for the job.
