How can I advertise on different forums where users are talking about my competitors?

In my experience, starting out testing one against the other is ideal (i.e. running campaigns on each and seeing which performs better). It's also important to look at what your immediate and long term goals are for the spend. Are you trying to sell them something now, keep them engaged for a later release of a product, or some other action? The key thing to note is that depending on what you're selling and what your keywords are, the bar can be a lot lower in terms of your bid per click if you go with Facebook Ads. Additionally: you can hyper target your audience with Facebook Ads like whoa (Google Ads are more limiting). Ex: I ran both sets of ads for a new line of ballet inspired barre-wear (targetting both ballet dancers and barre students). Both Facebook and Google Ads were linked to the sales page. For Google Ads: I used keywords like "barre-wear" (low search volume) "ballet attire" "activewear" (limited relevance) and about 20 other related terms. The spend to results ratio here was underwhelming. Keep in mind: I've only been working with Google Ads for a couple of years now. Better results are possible if you've got someone with 5+ years of experience who knows the system backwards and forwards, but for the most part, Google Ads are not DIY friendly if you want serious results. For Facebook Ads, I did 2 campaigns: 1. Ballet Dancers: I targetted women in major cities (NY, Chicago, Atlanta, Los Angeles), who were under 26 and fans of ballet companies and schools in their city, and also those who were fans of major dance supply companies. 2. Barre Students: I targetted women nationwide who were between 26 and 52, married, above average household income, fans of barre studios in their area, fans of Lululemon Athletica (high end activewear brand), and did a couple of variations on different hobbies and activities to target specifically stay at home moms or wives who were active. The results: $100 in ad spend // over 150 clicks to the product page // 20 new email newsletter signups // 3 immediate sales // 2 follow up sales within that week (so for a $100 product the ad yielded about $500 in sales that week from individuals who could be potential customers again (and 20 new people to market to for future sales).

It all depends on whether they are all selling the same thing to the same persona. If yes, then combine all the campaigns into one adwords account, which feeds into one analytics account. That way they can get feedback on the effectiveness of different keywords, ads, etc. more quickly (because there will be more data, from all the different websites, all in one place, for a particular keyword). If they are each selling different things, or to different personas, then don't combine their accounts, because it will just make things confusing and not useful from an analysis perspective.

Advertising is one of the ways to get traction, but for most brands it takes over 6 months (or a year) to build any income at all. It's a good way to promote local stores or coffee shops, and cheaper products, but the cost per click is high for online products and the initial investment is significant, and often acquiring a customer costs more than profit. For some brands getting a large number of initial users is essential to get the business profitable at a later point. Many startups invest in different forms of inbound or content marketing and build their steady traffic from freebies, tutorials and other relevant resources for their users, referral programs, freemium models and other tactics to bring users without investing in standard advertising. Advertising is a helpful addition when you implement retargeting pixels and promote to the right channels.

Make sure you've setup advanced analytics. You'll get a better picture of which conversions were direct, and which ones were assisted by another channel. Use tags and make sure your urls include all the detailed parameters - note that savvy users might truncate that link, so use a link shortener (like bit.ly) to mask it.

The answer depends on your situation: You could be a start-up that is more concerned with not blowing tons of money, or you could be in a rush to be done. In both situations, your objective is to find inventory sources that work quickly and then massively scale into those inventory sources. I am going to assume that the goal is to be efficient. In this case, I would start with relatively few inventory pieces and a pretty low bid. The goal of your experiment is to determine what inventory DOESN'T work while spending as little money as possible. By concentrating your spend on a few pubs, you can get to significant results quickly. If you spread out your spend, you won't generate enough clicks or backend actions per inventory source quickly enough to determine if one is actually working. (In my latter user persona, you can simply spend gobs of money to get significant results on lots of inventory quickly.) So the moral of the story is that you want to get to results, you have to scale the number of pubs you work with to align with the amount of money you are planning to spend. You would like to, within a day or two, rule out bad inventory and focus on new inventory, or alternately, make massive investments in working inventory to print money for yourself. I would be happy to do a call to further discuss.
