If you manage content production, you need to distinguish help creating an article from checking whether the draft addresses its intended subject. Frase researches a topic, helps write the article, and then watches the published page for decline. It is the cheapest content optimization product in this comparison set, from $39 a month billed yearly. OppAlerts does not write and does not alert on decline, and it measures a draft against a different reference.
OppAlerts publishes this comparison. Frase is cheaper, it writes, and it watches published pages for decline. OppAlerts does none of those.
What Frase sells
| Billed yearly | Monthly | Includes |
|---|---|---|
| $39/mo | $49/mo | 10 articles, 50 audit pages a month; Content Guard watches 10 pages |
| $103/mo | $129/mo | 3 seats, 5 sites, 40 articles, 250 audit pages; Content Guard watches 75 pages |
| $239/mo | $299/mo | 5 seats, up to 10 domains |
Extra seats are $29 a month, and articles, audit pages and AI prompts can be added as you go. OppAlerts is not sold by the seat, which is the main structural difference on the commercial side.
Two Frase capabilities have no OppAlerts equivalent. It writes and optimizes articles, and OppAlerts does not write. Content Guard watches published pages and identifies declining performance; OppAlerts has no such alert.
Frase optimizes for Google; the reference matters
Frase describes its own work as scoring pages and improving their Google rankings, and Content Guard monitors declining Google performance. That is a clear statement of what it optimizes against.
OppAlerts Content Optimizer compares the meaning of a draft with categories you choose from a taxonomy. Select up to three categories, one from each taxonomy. The report returns the nearest categories and identifies your intended category. It also lists related phrases the draft does not contain.
The two answer different questions. Frase asks how your page compares with what performs in Google for a topic. OppAlerts asks whether the writing reads as being about the subject, audience, industry, product type or city you selected.
An example makes the difference concrete. Suppose you write a guide for clinic managers choosing a medical billing service. A topic-based score can be high because the billing vocabulary is present. A category comparison may return medical billing services as the nearest match instead of the practice-management audience you selected. That result indicates an article written about the supplier rather than for the buyer, which is a structural problem no term count reveals.
Neither measurement predicts whether an AI engine or a search engine will cite the page. The OppAlerts editor reads up to 8,192 bytes, so a long article is reviewed in sections whose results do not combine into one score.
Where OppAlerts covers work Frase does not
Nothing on the Frase pricing page describes a backlink index, a link gap report, opportunity-type prospect search, website contact data, a news and blog index, PageRank history, or rank tracking of any type.
- Tracking of ChatGPT, Gemini and Google AI Mode answers, plus Google and Bing keyword positions, where one Google request returns the organic results, the ads and the AI Overview together.
- Prospect Index, searched by meaning as well as keyword across opportunity types: guest contribution pages, resource lists, expert roundups, podcasts, industry directories and award programs.
- Site Info, returning the stored public contact pages, emails, phone numbers and social profiles for a site.
- Backlinks DB: Link Gap and Brand Unlinked Mentions, for the link work that follows publication.
- News Index and Content FAQs, the latter drawing questions from LLM answers, search results, news and prospect pages.
- A US Cities taxonomy for checking whether writing reads as relevant to a specific city.
These run from one campaign definition holding the business, its brands, its competitors and three buyer personas.
Choosing between them
Choose Frase when the team writes regularly and wants research, drafting, optimization for Google and monitoring of declining performance in one low-cost subscription.
Choose OppAlerts when the writing already exists and the question is which audience it reads as being for. It answers that; it does not draft, and it will not tell you when a published page starts to slip.
A small content team can run Frase at $39 a month alongside OppAlerts without much duplication, since the only shared step is scoring a draft, and the two scores measure different things.
