4,236 businesses in Sarıyer: how many have a website?

How many businesses in a given district have a website is not a number anyone measures regularly in Turkey. We measured it for Sarıyer. In September 2026 we collected 4,236 business listings across 22 neighbourhoods of the district and its surroundings from Google Maps, and read the phone and website field of each one. The figures below are the result.

One in two businesses with a phone number has no website

Measure	Count	Share
Listings scanned	4,236	100%
Phone field filled	3,514 / 4,236	83%
Website field filled	1,933 / 4,236	46%
Has a phone, has no website	1,765 / 3,514	50%

The last line is the finding. Of the 3,514 businesses that published a phone number, meaning businesses that want to be contacted, half have an empty website field. Someone who wants to reach them sees the listing, reads the reviews and finds a phone number as the only option. Price range, service list, how the business works and what it has done before cannot be learned without calling.

What each field in a listing does is explained on our what is a Google Business Profile page.

A twenty-seven point spread across one district

The rate is not spread evenly. Among listings that publish a phone number, the share without a website by neighbourhood is as follows.

Neighbourhood	With a phone	No website	Share
Yeniköy	123	78	63%
Tarabya	183	114	62%
Bahçeköy	218	119	55%
Zekeriyaköy	729	370	51%
Sarıyer centre	447	227	51%
Demirciköy	137	68	50%
Ayazağa	305	148	49%
Göktürk	485	231	48%
İstinye	142	68	48%
Maslak	274	99	36%

The gap between Maslak and Yeniköy is twenty-seven points. Maslak standing apart is expected: companies with head offices in the business district list their corporate site. Along the Bosphorus the businesses are mostly local ones that live on word of mouth.

Searches are usually made with a neighbourhood name, which makes this table matter more. A business already appears when someone searches for it by name; appearing in a search phrased as “in Tarabya” requires a page about that neighbourhood. We wrote about how that is built on our web design in Istanbul page.

A quarter of those without a website are established businesses

The 1,765 businesses without a website are not all small. Their distribution by review count is as follows.

Review band	Count	Share
No reviews	193	11%
1 - 9 reviews	515	29%
10 - 19 reviews	288	16%
20 - 49 reviews	342	19%
50 - 99 reviews	183	10%
100 and above	244	14%

Seven hundred and sixty-nine businesses with more than 20 reviews have no website. Two hundred and forty-four with more than 100 reviews have no website. Forty-five with more than 500 reviews have no website. These are businesses that have traded for years, that have customers, and whose customers were pleased enough to leave a review.

Same satisfaction, twice the visibility

Placing the two groups side by side gives this.

Measure	With a website	Without
Average rating	4.54	4.50
Median review count	39	19
Mean review count	338	83

The rating gap is four hundredths of a star. In terms of customer satisfaction there is no meaningful difference between the two groups; businesses without a website are not doing worse work. The difference is in visibility: the median review count differs by a factor of two and the mean by a factor of four.

Read together, the two numbers say this: the absence of a website is not a quality problem, it is a reach problem.

A caution belongs here. This measurement does not prove that a website increases review counts. A larger business may both commission a website and reach more customers; cause and effect cannot be separated from this data. What the measurement does support is that the number of businesses with customers but no presence online is high.

Method and limits

The measurement was made on 22 September 2026. Listings were collected from Google Maps. These 22 neighbourhoods were included: Sarıyer, Zekeriyaköy, Tarabya, Yeniköy, Emirgan, İstinye, Bebek, Rumeli Hisarı, Rumelifeneri, Maslak, Ayazağa, Kilyos, Bahçeköy, Göktürk, Kemerburgaz, Uskumruköy, Demirciköy, Büyükdere, Baltalimanı, Kireçburnu, Poyrazköy and Garipçe. The neighbourhood breakdown was read from the region field of each listing; the address field ends with the district name in every record, so counting from it would have been misleading.

There are four things this measurement cannot see. First, a business with an empty website field may still have a website and simply not have filled the field in. The outcome is the same, because a visitor arriving from the map cannot see that site. Second, the websites themselves were not opened, so this report says nothing about their quality. Quality is a separate measurement and we made it for the fish restaurants on the Bosphorus. Third, social accounts were not counted; a business may have no website and still work well through Instagram. Fourth, listings of closed businesses remain on the map for a while and were not separated out.

Business names were deliberately not published. The report describes the district, not individual businesses.

What the numbers say

Three conclusions follow. First, one in two businesses in Sarıyer that publishes a phone number has no website, and the rate ranges from 36 to 63 per cent depending on the neighbourhood. Second, this is not confined to small businesses: 244 businesses with more than 100 reviews have no website. Third, there is no difference in customer satisfaction between businesses with and without a website, and a twofold difference in visibility.

A listing on the map brings a customer to the door. What sits behind the listing decides whether they come in. In Sarıyer, for one thousand seven hundred and sixty-five businesses, there is nothing behind it yet.
