IMO: If you are finishing up a side project iOS / Android app, don't bother with a website. Just get it out of the door! Traffic doesn't drive itself to the website. If you drive traffic somewhere, you may as well drive it directly to the App Store.<p>There is no reason a quickly cobbled together website that has the same screenshots your App Store listing has will convert any better than the App Store.<p>Plus, the iTunes web page is pretty good at SEO and will probably turn up before your own page for relevant keywords.<p>In fact, the time you save by not building a Landing Page, you can invest into:<p>a) Writing a great description of your app. Also includes relevant keywords for your niche, you may want to use a keyword-research tool. <a href="https://searchman.com/" rel="nofollow">https://searchman.com/</a> seems to be the best free tool atm(?).<p>b) Make sure your screenshots not only show meaningful data, but also clearly communicate why/what your app is useful for, e.g. how a problem is solved. Explainer texts can make it A LOT easier to communicate that. Shameless plug of a side project of myself: <a href="http://www.screenscott.com" rel="nofollow">http://www.screenscott.com</a><p>c) When the app is live, make sure it gets downloaded and reviewed. Tip: Ask friends / family to download the app and give you feedback. If you get criticism -> Great, you'll know what to do next. If you get positive feedback -> Great, they've already written the review! Now you just need to ask them to post it in the App Store :-)
