Hello! I am looking for a freelancer to set up offline conversion tracking in Google Ads.Part of the work has already been done: when a person clicks on the ad and submits a request, it goes into the CRM along with a special click code (GCLID) — so the link "who came specifically from the ad" is already established and stored. The last step is missing: when the request in the CRM turns into a real sale, this information does not return back to Google Ads. Because of this, the ads are optimized only for requests, not for actual sales.It is necessary to set up so that sales data is automatically sent back to Google Ads and counted as a conversion.The CRM has an API and webhooks, so technically this can be implemented without problems — I need a person who: will check and adjust the reception of such conversions in Google Ads if necessary; will connect to the CRM and Google Ads and set up automatic data transfer about sales without manual work; will test to ensure that the data is transmitted correctly (correct date, amount, correct display); will briefly explain how it works and what to do if the transmission ever stops.Access to the CRM and Google Ads will be provided separately, after agreement.

Task Description: I need a ready-made, pre-written template (Boilerplate / Headless CMS) for an online store on the Next.js stack + Node.js with an admin panel. You do not need to write code from scratch, come up with a complex architecture, or create a unique design.The task is to take a ready-made solution, deploy it, change a few background images, adjust the structure to your specifications, and upload the site to hosting.What the result should be (structure of the target page from top to bottom): Main Screen: Your ready-made design. We will simply replace the background image. You need a "Call" button (the call is made directly to the mobile phone, and the "Name/Phone" form is for PC). Service Description: a simple block consisting of exactly three paragraphs of text. Product Showcase: a grid of product cards from your template. The only condition is that the products must have "New" and "Used" labels (and a quick filter). The "Buy" button opens a simple order form (name, phone, selected product). There is no online payment. Video Reviews: a block where videos (links from YouTube) are strictly in one line. It is important that the loading is lazy so that the videos do not slow down the website. Footer: Contacts and links to messengers.Admin Panel Requirements (Node.js): We use the standard admin panel from your template. It should be able to add products (Name, Price, Photo, Description, New/Used labels) and insert links to videos for the reviews block.All requests from the site (calls and purchases) should be directed to a Telegram bot (the notification script must be connected).
