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

Claude 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 Claude 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.

Monthly competitor memo

Ask Claude

From Monthly Visit Data, compare Visits, Bounce Rate and Pages per Visit for our Domain and our three competitors last month, then draft a short memo for the leadership update.

The head of growth gets a written comparison with the numbers behind it, edits two sentences and sends it, instead of rebuilding the same table from Similarweb every month.

Market entry shortlist

Ask Claude

Rank countries by Share of competitor Visits where our Domain has a worse Rank, and list the five with the biggest gap.

Before the planning offsite, the international marketing lead brings a shortlist of countries where rivals already win attention and the team is underrepresented.

Benchmark file for the analytics repo

Ask Claude

Use the dataddo server to read weekly Visits - all traffic for every tracked Domain over the last two months and write benchmarks/similarweb-weekly.csv.

A marketing analyst runs Claude Code inside the reporting repository, commits the file and lets the dashboard build read it, with the query noted in the commit message.

With vs. without

Similarweb in Claude, with and without Dataddo

Without Dataddo With Dataddo Outcome for you
Competitor comparison Someone opens each competitor in Similarweb, copies visits and engagement into a spreadsheet and pastes the table into a chat to get a summary. Each domain has its own source and every row carries Domain, so Claude compares sites from the extracted data in one question. Benchmarks without copying
Country view Country splits are checked one market at a time, so the strongest markets of each competitor are guessed from a few screens. Monthly Visit Data lists Visits, Share and Rank per Country and Country Code, so Claude ranks markets across all domains at once. Every market in one answer
Shared numbers in the team Every marketer exports a slightly different date range, and the leadership deck quotes figures nobody can reproduce. On Team and Enterprise an Owner adds the connector once, and each member signs in with their own Dataddo account to the same flows. One set of benchmark figures
Token consumption Claude 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

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 Claude: FAQ

How do I connect Similarweb to Claude?

Authorize Similarweb in Dataddo with an API key, then create one source per domain with datasets such as Monthly Visit Data and Visits - all traffic. Attach the flows to a Claude destination or AI Model, then add Dataddo Data Access from the Claude connectors directory and sign in with your Dataddo account.

What do I need from Similarweb to connect it?

An API key. In Similarweb go to Settings > Account, under API select Standard API / Batch API, click Generate a new API key and paste it into the Dataddo authorizer. The Dataddo docs do not list a required Similarweb plan.

How do I add competitors so Claude can compare them?

Create one Similarweb source per domain, entering a single domain such as example.com in each. Every row carries the Domain field, so Claude can line up your site and each competitor in the same answer.

Can Claude see traffic for a single country?

Yes, if you set it on the source. Most datasets take a Country filter, with world as the default for worldwide data. Monthly Visit Data returns one row per Country instead, so no filter is needed there.

Why does Claude not see last year's traffic?

Each dataset reads a relative date range that moves forward with the current date, and every run replaces that window. Run a full data re-sync with a wider range once to load earlier months.

Can I use Similarweb data in Claude Code?

Yes. Signed in with your Claude account, Claude Code loads the Dataddo connector automatically, so you can query Similarweb entities from the terminal while you work in a repository.

Can I control which Dataddo tools Claude uses?

Yes. Claude lists the connector's tool permissions, and for each tool you decide whether Claude may use it freely or must ask you first. Access is read-only, and nothing is sent back to Similarweb.
