How did our traffic and engagement compare with our two closest competitors last month?

ChatGPT Answer · Similarweb

Last month ourshop.com had 1.42M visits, behind rivalstore.com at 2.05M but ahead of shopnext.com. Our Bounce Rate was the lowest of the three.

DomainVisitsBounce RatePages per Visit
rivalstore.com Monthly Visit Data 2,050,00048.1%5.2
ourshop.com Monthly Visit Data 1,420,00041.7%5.9
shopnext.com Monthly Visit Data 980,00052.3%4.4

Monthly Visit Data has one row per Country, so Visits are summed across countries while Bounce Rate and Pages per Visit are weighted by Visits.

Questions ChatGPT can answer from your Similarweb data

Similarweb estimates website traffic and engagement for your own domain and for competitors. Dataddo extracts visits, bounce rate, pages per visit, visit duration, country split and traffic sources per domain, so marketing can compare sites in plain language.

Did the campaign move traffic?

Ask ChatGPT

Compare daily Visits for our Domain in the two weeks before and after 14 September, and show Paid Visits by Source Type on desktop for the same days.

The performance marketer approves each query, then posts a before-and-after view in the campaign channel instead of waiting for the monthly report to confirm the lift.

Organic versus paid mix

Ask ChatGPT

For each tracked Domain, what share of desktop traffic came as Organic Visits versus Paid Visits last month, by Source Type?

The SEO lead shows where competitors buy their traffic and where they earn it, which shapes the next quarter's split between content and paid search.

Engagement after a redesign

Ask ChatGPT

Run data_status on the Similarweb flows, then show weekly Bounce Rate and Pages Per Visit for our Domain since the redesign went live.

The web team sees whether the new layout kept visitors longer, knowing from data_status how fresh the figures are before they report back.

With vs. without

Similarweb in ChatGPT, with and without Dataddo

Without Dataddo With Dataddo Outcome for you
Channel breakdown The analyst screenshots the traffic sources view for every domain and asks ChatGPT to read numbers from images. Traffic Sources Overview - Desktop and Mobile Web hold Source Type with Organic Visits, Paid Visits or Visits, so ChatGPT queries real values. Channel mix from data, not images
Knowing what was used After a file upload, nobody can tell which rows or date range produced the summary in the chat. ChatGPT asks you to confirm each tool call, so you see every Similarweb lookup before results appear. Every lookup approved
Questions the data cannot answer The model guesses at numbers for a country or device you never extracted. ChatGPT can call known_gaps, which lists what the connected data cannot answer, for example a country you did not filter for. Fewer invented figures
Token consumption ChatGPT spends tokens exploring raw Similarweb columns, sampling rows and retrying until it understands the data. Field definitions and relations are supplied up front, so the model skips the exploration and goes straight to the answer. Fewer tokens per answer
Answer quality Prone to wrong joins, invented fields and numbers that are hard to check. Answers grounded in defined fields. In the Dataddo benchmark, 78.5% of questions were answered correctly, against 65.5% with plain CSV files. Better answers

Benchmark

More right answers. Half the confident mistakes.

We asked 43 pre-registered questions of three real datasets - Google Search Console, HubSpot deals and Google Ads - and delivered the same rows to the same model in four ways. Only the data layer changed.

78.5%

of questions answered correctly - the best of the four delivery methods tested

2x

fewer confidently wrong answers - 14.0% of runs against 24.0% and 26.3%

2.8x

more correct answers on messy CRM data - better on 8 questions, worse on none

Answered correctly All 43 questions - higher is better
Wrong, but stated as fact Share of runs - lower is better

Same model, prompts and rows in every condition; 759 graded runs, ground truth frozen before any run. On Google Search Console alone, documented CSV files did as well as Data to AI™ - the advantage comes from messier data such as HubSpot deals.

FAQ

Similarweb and ChatGPT: FAQ

How do I connect Similarweb to ChatGPT?

Add a Similarweb source in Dataddo with your API key, a domain and datasets such as Traffic Sources Overview - Desktop, then attach the flow to a ChatGPT destination or AI Model. In ChatGPT on the web, turn on Developer mode, create a Dataddo Data Access app with https://headless.dataddo.com/mcp-data and OAuth, and sign in.

Which ChatGPT plans can query Similarweb through Dataddo?

Developer mode is needed, on the web only, and it is available on Pro, Plus, Business, Enterprise and Education. On Business and Enterprise, a workspace admin may need to allow developer mode first.

Does ChatGPT ask before it reads Similarweb data?

Yes. ChatGPT asks you to confirm each tool call. In the app settings you can also turn individual Dataddo tools on or off, for example to leave refresh disabled.

Can ChatGPT compare desktop and mobile traffic sources?

Yes, if both datasets are extracted. Traffic Sources Overview - Desktop splits Organic Visits and Paid Visits by Source Type, while Traffic Sources Overview - Mobile Web gives Visits by Source Type.

Are the numbers ChatGPT reports exact visit counts?

No. Similarweb returns estimated traffic for a domain, and Dataddo passes those estimates through unchanged. Treat them as benchmarks for comparing sites rather than as your own analytics.

Can I choose daily or weekly data?

Yes. Datasets such as Visits - all traffic and Bounce rate - all traffic offer Daily or Weekly granularity when you create the source. Monthly Visit Data is monthly only.

Can ChatGPT change anything in my Similarweb account?

No. ChatGPT reads extracted data through the semantic layer by entity and field name. Dataddo never accepts SQL from the model, and nothing is written back to Similarweb.
