Content optimization tool: bring your best old posts up to date.
Kaku reads a published post, works out what has gone stale, and proposes each update on its own: a figure to correct, a paragraph to rewrite, a section the topic now needs. You keep the ones you agree with.
Content Refresh
Analyze postsNobody rewrites old posts. They just fall down the results.
The post that brought you traffic two years ago still says "this year", still recommends a product that was discontinued, and still misses the section every competitor now has. None of it is wrong enough to delete, and opening the editor means rereading two thousand words to find the forty that need changing — so the post stays as it is, and a newer page takes its traffic. That's content decay, and it rarely announces itself.
What Kaku looks for
Thin or vague sections
Paragraphs that fill space without answering the question the heading promised.
New paragraphs and sections
A subject the post mentions in passing that now needs a paragraph, or a section of its own.
Gaps the results show
Subjects every page ranking for your keyword covers, and yours does not mention.
Numbers out of date
Prices, dates, version numbers, "as of 2023" — anything stated as current that no longer is.
Not a new post. A list of changes.
Each one is separate, colour-coded by kind, and you keep or drop it on its own. Reject them all and the post stays exactly as it was.
How the content optimization tool works
Pick your old posts
Sort by publication date and select the ones that used to do well. Nothing is read until you run it.
Kaku reads them
It compares the post with the pages ranking on Google for its keyword, the way content optimization software should, and builds a plan of up to eight separate changes.
Keep or drop each change
Every proposal shows the current text and the replacement, with the reason. Drop the ones you disagree with.
Publish what you kept
Only the changes you kept are written back. The post keeps its URL, its publication date and its comments.
A content audit tool for every post you've published
Select every post you want checked and run them in one go. Kaku analyzes each one, marks the ones that still hold up as up to date, and leaves the rest ready to review.
An afternoon of reading turns into a list you can work through in ten minutes.
Numbers that aged out
Prices, stats and version numbers that were right when you wrote them and quietly stopped being right.
What the post never covered
The questions readers ask now that did not exist when you published. Kaku drafts the section.
Not a single made-up figure
When there's no reliable current figure, Kaku rewrites the sentence so it won't date instead of inventing a number. Your post stays current without losing credibility.
Already up to date? You don't pay
When a post still holds up, Kaku tells you so and charges no credit. You only pay for the posts that actually need work.
