No Problem Fact Of The Day: Every 6 months, the internet doubles in information.
Not to mention nearly everything is controversial online, so this is why I try and write the pros and cons for each reply as there is no such thing as a perfect answer.
This landing page seems a bit to overwhelming. I dont even know where to look. In my personal opinion I would have much less click-throughs with a site like thewirecutter.com
I prefer the more simple, yet informative landing page. Color scheme white, dark grey text, light grey text boxes (slightly darker than the background), and a feature color such as blue, red, orange, green or something which makes your CPA stand out. This will help your clickers to know where to click next. You basically want to have good content (to make the page look legit), but direct their eyes to the feature color to secretly direct them where to click without the use of arrows, and other flashy (tacky) methods. This method is basically gaining the trust of the viewer instantly without even reading much of the content. I will always use either a picture or a video since they say a thousands words, and people now days are more likely to watch a video vs read an article.
Bottom line, keep it simple, yet content rich (not to the point of clutter), with a feature color, and a picture or video.
Completely depends on whether or not the campaigns are relevant to each other and if they look spam like or not. Remember you are looking for quality. Placement is also important as your other campaigns are the second priority, so they should not stand out more than your featured campaign.
I can see both sides to this, and I think balance needs to come into play. I think people will take this and go to the extreme. I personally would never use an ugly page. Clean and simple is what I prefer.
Take a look at BootStrap themes and website examples. They are super clean, simple, and compatible on every device which is perfect for Instagram since most of your visits are coming from smartphones.
This is based on my own experience of what I have found to work the best. Others may have success using other methods so keep your mind open to other ideas, or mix mine with someone else's idea to create the perfect landing pages.
It may be worth it to purchase a premium template which you can then utilize on all your landing pages. Its worth it if you can use the template for unlimited sites.
