Trick to index infinite scroll content on Google?

Question

• I have a Question & Answer website, sort of like stackoverflow.
• When you open it, it displays 20 latest questions.
• When scroll to bottom of page, and it fetches 20 more, and so on, infinitely.
• Each question has its own page, just like here.

So my trick is create a empty page that contains only <a href='question_link'> links to 100 latest questions, followed by a link to the next 100 latest questions. No text, only links. Example:

Fake page 1

<a href='/question/1'></a>
<a href='/question/2'></a>
<a href='/question/3'></a>
<a href='/question/4'></a>
...
<a href='/nextpage?after=100'></a>

Fake page 2

<a href='/question/101'></a>
<a href='/question/102'></a>
<a href='/question/103'></a>
<a href='/question/104'></a>
...
<a href='/nextpage?after=200'></a>

and so on, until all questions are exhausted. Notice it has no text, no page title or page description, this is to avoid Search Engine from indexing it.

My question is, would Google allow something like this? I mean it's fully legitimate, and all we're doing is telling Google about the URLs of our pages, so it's okay right?

Answer 1

Don't do this. This will create a bad ranking page, with duplicates (the next/prev pages) and will cost your more than you will gain.
Rule of thumb: Don't make pages just for bots.
To prefent indexing you could just add the robots metatag with the value NOINDEX.

What you need is a sitemap xml :) Those are perfect fort situations like this; To indicate pages which cant easily be found by crawling.
Also, if you have Google Analytics, they'll find the pages because you trigger the code on those pages. Also, if you have visitors using Chrome, they'll find the pages.

Long story short / TL;DR:
Do the sitemap, and don't worry, you'll be found.
