I’m writing this in a simple way so a business owner can use it without technical knowledge. Goal: in about 60 minutes, find where your website is losing speed, Google traffic, or customers. Use this as a step-by-step checklist. First detect the problem, then fix it. 1) SPEED (Performance) - If the site “feels ready” later than 2–3 seconds, people leave. - Test on mobile internet (4G/5G), not only office Wi-Fi. - Biggest причина of slow sites: huge images. If one image is 5–10MB, the page dies. Fix: resize + convert to WebP/AVIF. - Too many sliders/animations look nice but usually slow everything. 2) TECHNICAL SEO (So Google understands your site) - Sitemap: do you have it and is it up to date? - Robots.txt: are you blocking important pages by mistake? - Canonical: if the same page exists under multiple URLs, Google gets confused. - Multilingual (AZ/EN/RU): hreflang must be correct, otherwise Google shows the wrong language. Quick test: Search your brand name in Google. If it shows the wrong language page, hreflang/canonical is likely wrong. 3) CONTENT (Text that ranks and sells) - In 5 seconds, is it clear what you do? “We are professional” is not a message. Say exactly what you build and for whom. - Each service should have its own page (better for SEO). - Add real examples: what you did, what changed, what result you got. 4) CONVERSION (Turning visitors into leads) - Phone/WhatsApp must open with 1 click. - Forms should be short: name + phone + message is enough. - If you don’t show prices, at least show “starting from” or packages. 5) TRUST (People must believe you) - Portfolio: real projects with short explanation + result. - Reviews/testimonials and partner logos help. - Address and contact info should be visible. Result: With this checklist you don’t just say “something is wrong”. You find the exact place where the site is losing money. If you want, KeyTD can do a mini-audit and give you a clear fix plan.
