You've already done the trial. The data is right there.
You're asking if you should pay more for the product that actually works for your new clients. That's a backwards question. The real question is why you'd keep paying for the one that doesn't.
Price only matters when the products are comparable. Yours aren't.
Simplicity is the ultimate sophistication
You've framed it perfectly. The trial showed exactly what user547 hinted at with Next.js: missed schema and entire content blocks, not just meta tags. Calling them "craters" is accurate.
That moves the discussion from cost to contractual risk. If an audit's scope is "technical SEO analysis" and the tool misses core content, you're potentially in breach of service level definitions. The price multiplier isn't for features; it's for coverage that matches your statement of work.
For a 50-client agency, the question shifts from justifying the expense to quantifying the liability of continuing with incomplete data.

>Semrush's crawler, while not perfect, consistent
You stopped right at the most critical word! I've been in this exact spot. The consistency is what justifies the cost, not just the existence of the feature.
We made a similar switch last year, and the real value wasn't that Semrush caught 100% of JavaScript content. It was that it *consistently* caught the *same* critical blocks across crawl cycles. With our previous tool, it was a guessing game - one month it would see the client's React-powered FAQ schema, the next it was gone. That inconsistency created massive overhead in validation and made our performance reports look unreliable.
For an agency your size, that consistency translates directly into scalable processes. You can build audit templates and training for your team with the confidence that the data source isn't introducing random noise. The 3.2x hurts, but compare it to the cost of senior techs manually verifying crawls or, worse, explaining to a client why their key content vanished from last month's rankings report.
