Audio is not a ranking factor on its own. Here is what an audio version can do for readers, what to measure, and where to put the player.

Is audio blogging good for SEO?

ButterReader adds an audio version next to your written post, and that is the honest way to frame audio and SEO: it does not replace the text search engines index, and it is not a ranking factor on its own. What it can do is give visitors a second way to consume the page, which matters if they would otherwise leave before reading. Whether it moves your rankings depends on whether your readers actually use it, and you can measure that.

Does adding audio change how Google ranks a page?

ButterReader's player does not change what Google indexes: the article text stays on the page as HTML, and the player loads alongside it. Google has not published any rule that rewards pages for having an audio player. Claims that audio raises rankings by a fixed percentage are not backed by public data, so treat any such number with suspicion, including ones you may have seen on this blog before.

What is reasonable to say:

The text still does the ranking. Headings, clear answers and internal links are what search engines read. Audio sits on top of that, not in place of it.
Engaged visitors are a good sign, not a lever. If a listener stays to the end of a post, that is a better experience for them. Google does not confirm using time-on-page directly, so think of it as a user-experience win first.
Accessibility is worth doing for its own sake. A listen option helps people who find long text hard to read. Do it because it serves them.

What should I measure after adding audio?

ButterReader's player reports plays, listening time and completion, so you can see whether readers use the audio version before deciding it is worth keeping. A useful routine:

Add the player to a handful of posts that already get search traffic.
Leave it for a few weeks.
Compare plays and completion with that page's traffic in Search Console and your analytics.
Keep audio where people press play; move the player or rethink it where they do not.

Where should the player go on the page?

ButterReader recommends placing the player above the fold, under the post title. A player at the bottom of a long article is rarely pressed, because anyone who wanted to listen has already scrolled away or left.

Does audio make my content a duplicate or thin?

No. ButterReader generates audio from the text already on the page, so you are not publishing a second copy of the article. Thin content is about the page offering little value; a short post with a player is still a short post. Fix the writing first.

How do I add audio to a blog?

ButterReader works with one line of embed code: create a player at app.butterreader.blog, style it, and paste the snippet into your post or template. The widget finds the article text and narrates it. Step-by-step guides: WordPress, Wix, any website.
