How Indian websites add the WhatsApp button: builders and plugins behind 24,714 homepages

Shruti Agarwal (an invented example) runs a twelve-person leather goods export business in Kanpur. Her website is WordPress, built by a local agency in 2023 on a page-builder theme, with a green WhatsApp button fixed to the bottom-right corner of every page and her sales manager’s number behind it. Buyers from Dubai and Hamburg tap it at odd hours, and the chats live on his phone. She has never looked at how the button was added, and she has not needed to. If she did, she would find herself in the biggest group there is.

WordPress sits behind 39.2% of the Indian homepages that link WhatsApp, and Elementor, a WordPress page builder, behind 32.2%. We know because we read the HTML of all of them.

Two sentences on method. In August 2026 we read the archived HTML of every .in homepage in Common Crawl’s monthly crawl archive, 113,102 of them, one per registrable domain, and looked for WhatsApp click-to-chat links, the code of WhatsApp platform vendors and generic chat widgets; for this article we went back through the cached pages for a second set of markers, the builders, plugins and other links described below. The full method and every caveat are in our study of WhatsApp on Indian websites.

Three caveats for this piece. We read homepages only. The base here is the raw set of 24,714 homepages with a WhatsApp link (21.9% of 113,102), before the cleaning step that removes parked pages and placeholder numbers and leaves the 24,059 our study quotes. And a marker is a literal piece of code in the page, such as /wp-content/ for WordPress or cdn.shopify.com for Shopify; it is evidence of code on the page, not of an active account, and a site that hides its builder’s paths is counted as none of these.

Which site builders are behind the WhatsApp button?

WordPress, by a distance, which is also true of the .in web as a whole. The last column is our arithmetic: the WhatsApp-linking count divided by the all-homepages count, so 672 divided by 2,620 for Shopify.

Marker	All .in homepages	Share of 113,102	WhatsApp-linking homepages	Share of 24,714	WhatsApp-linking share of that builder
WordPress	47,279	41.8%	9,679	39.2%	20.5%
Elementor (WordPress page builder)	32,839	29.0%	7,970	32.2%	24.3%
WooCommerce	22,211	19.6%	5,423	21.9%	24.4%
React or Next.js	5,285	4.7%	1,292	5.2%	24.4%
GoDaddy builder	4,650	4.1%	945	3.8%	20.3%
Wix	3,594	3.2%	557	2.3%	15.5%
Shopify	2,620	2.3%	672	2.7%	25.6%
Blogger	1,404	1.2%	209	0.8%	14.9%
Webflow	509	0.5%	112	0.5%	22.0%
Zoho Sites	157	0.1%	48	0.2%	30.6%
Squarespace	161	0.1%	41	0.2%	25.5%

Elementor and WooCommerce run on WordPress, so the rows overlap, and one homepage can carry several markers. Two readings follow. WhatsApp-linking homepages are about as WordPress-heavy as the .in web as a whole (39.2% against 41.8%), with Elementor and WooCommerce a little over-represented (32.2% against 29.0%, and 21.9% against 19.6%). And the rate at which a builder’s sites link WhatsApp varies: Shopify homepages link it at 25.6%, Wix at 15.5% and Blogger at 14.9%, against 21.9% for the whole set. Zoho Sites’ 30.6% rests on 157 homepages, too few to lean on. Our Shopify WhatsApp integration guide covers what the 672 Shopify stores can connect beyond the button.

Which WhatsApp plugins and widgets do they use?

Mostly none we could name. The commonest marker is generic float-button markup, class names such as whatsapp-float, whatsapp-button or wa-widget, which is what a developer writes by hand or a theme ships with.

Marker	All .in homepages	WhatsApp-linking homepages	Share of 24,714
Generic float-button markup (whatsapp-float, whatsapp-button, wa-widget)	6,347	3,363	13.6%
Chaty	2,314	1,476	6.0%
Click to Chat (ht-ctc)	3,251	787	3.2%
Join.chat	1,389	316	1.3%
Elfsight widget	696	260	1.1%
QuadLayers WhatsApp Chat (qlwapp)	1,025	231	0.9%
NinjaTeam WhatsApp (nta-whatsapp)	727	199	0.8%
wa-chat-box markup	229	107	0.4%
GetButton.io	328	81	0.3%
WhatsHelp.io	126	46	0.2%

The five named WordPress plugins together, Chaty 1,476 plus Click to Chat 787 plus Join.chat 316 plus QuadLayers 231 plus NinjaTeam 199, come to 3,009 pages: about 3,000 of the 9,679 WordPress homepages that link WhatsApp, or 31% (3,009 divided by 9,679). The other two thirds of WordPress WhatsApp pages use the theme’s own button or one written by hand. These are counts of code on the page; the scan records nothing about how any of them work.

Click to Chat’s marker is on 3,251 homepages, but only 787 of them show a WhatsApp link in their HTML; Chaty is on 2,314, and 1,476 link WhatsApp. The likeliest reason, which we have not checked page by page, is that these plugins write the link with a script after the page loads, and some also carry channels other than WhatsApp. Our scan reads the HTML as crawled, so it sees the plugin and misses the link. That makes the 21.9% WhatsApp-linking figure a floor.

What else sits on a WhatsApp-linking homepage

A homepage with a WhatsApp button is a homepage that wants to be reached, and it shows in everything around the button.

Also on the page	All .in homepages	Share of 113,102	WhatsApp-linking homepages	Share of 24,714
Facebook link	49,005	43.3%	15,273	61.8%
mailto: link	40,049	35.4%	14,620	59.2%

Google Tag Manager	42,675	37.7%	12,734	51.5%
YouTube link	32,851	29.0%	10,017	40.5%
LinkedIn link	28,152	24.9%	8,677	35.1%
Razorpay	5,943	5.3%	3,987	16.1%
Meta (Facebook) pixel	8,755	7.7%	3,131	12.7%
Tawk.to chat widget	2,105	1.9%	888	3.6%

Three readings, with the arithmetic. A tap-to-call link sits beside the WhatsApp link on 58.2% of these pages, against 30.7% of all .in homepages: the businesses that want a chat also want a call, and the visitor picks. An Instagram link is on 56.2% against 36.1%, so for more than half of these businesses the WhatsApp chat and the Instagram DM are two doors to the same desk. And Razorpay’s script is on 16.1% of WhatsApp-linking homepages against 5.3% of all, three times as often (16.1 divided by 5.3 is 3.0). That last one needs its caveat said plainly: a payment script on the page means the site takes payments on the site, not that anyone is paid on WhatsApp.

Tawk.to’s 888 pages (3.6%, against 1.9% across the whole set) are sites running a chat box and a WhatsApp button side by side; our chat widget article looks at them.

Channel links, the Business app’s short link, and catalogues

Three smaller WhatsApp links turned up.

A WhatsApp Channel link (whatsapp.com/channel/) is on 1,258 .in homepages, but only 285 of them also carry a click-to-chat link. The other 973 (1,258 minus 285) offer a broadcast to follow and no way to reply. Our guide to Channels and Status covers what a Channel can and cannot do for a business.

The WhatsApp Business app’s own short link, wa.me/message/ followed by a code, is on 388 homepages, 1.6% of the WhatsApp-linking set. WhatsApp’s help centre says the app generates this link when the account is created, under Tools, then Short link, and that a default message can be set on it. It is correct by construction, which the hand-typed links in our link mistakes article often are not. The trade is that it shows a code, not your number, and it belongs to the app account.

A catalogue link, wa.me/c/ and the number, is on 38 homepages; our catalogue guide explains them. Thirty-eight of 24,714 says the catalogue is not how Indian homepages sell on WhatsApp. The button is.

What a button does, and what it doesn’t

Whatever added it, a plugin, a theme or a developer’s twenty lines of CSS, every one of these 24,714 buttons does the same thing: it opens a chat on the one number written in the link, on the visitor’s own WhatsApp, with the pre-filled line if there is one. Then the button’s job is over. The chat lands on the phone that holds the SIM, and nothing on the page knows it happened. There is no routing: a buyer asking about shipping and a buyer asking for a sample both land on the same handset, which rings in one pocket. There is no record outside that handset; if the sales manager leaves, the history leaves. Nobody is told which page the visitor was on, because the website’s analytics stop at the tap. And nothing follows up: if the visitor goes quiet there is no reminder, and if the business wants to write after 24 hours it needs an approved template on the WhatsApp Business Platform, which no plugin provides. Our guide to adding WhatsApp to a website has the pre-fill trick that recovers some of the page information. Nothing recovers the rest.

How to pick a button

If you are choosing one, the HTML in this scan suggests five checks, none of which needs a particular product.

• It writes the link as wa.me/ or api.whatsapp.com/send with the full international number, 91 and the ten digits for India. Our link mistakes article counts what happens otherwise: 1,988 homepages with a bare ten-digit number, 2,106 on web.whatsapp.com/send.
• It lets you set a different pre-filled sentence per page, so the first line tells you where the chat came from. Half of WhatsApp-linking homepages pre-fill a message and 3,135 of them still carry the default sentence of one hosted website package; the pre-fill article has what works.
• It has words on it (“WhatsApp us”), not only the icon.
• It does not sit on top of the cookie notice, the add-to-cart bar or another chat bubble on a small phone.
• The link is in the page’s HTML, not only written by script, so it works when the script fails.

When the button is enough, and when the inbox is the step

The button is enough when one person can answer every chat the same day and the history can live on that one phone. For a one-chair clinic, a tuition teacher or a three-person workshop, that is most days, and nothing in this data argues for more.

It stops being enough at the moment two people answer. From then on the question is not which plugin but where the chats land. A shared inbox on the business’s own number takes the same wa.me link, the same button and the same pre-filled sentence, and changes only what happens after the tap: the chat is assigned, the history stays with the business, and a reply after 24 hours is possible with an approved template. The 5.7% of numbered homepages that added a second number instead are the subject of our two-numbers article; it is the cheaper fix, and it halves the record.

Shruti kept the agency’s button and the agency’s plugin. She moved the number behind it from the sales manager’s SIM to a business number with three people answering it, and the next time the sales manager was at a trade fair in Germany, the Kanpur office answered the Dubai buyer at 11 pm from the inbox. Click to chat, template and 24-hour window are in our glossary if any of them is new.
