October to December is the most competitive period online for most businesses. Search volumes spike, ad costs rise, and customers are actively looking to buy — often with less patience for slow, confusing, or unconvincing websites. If your site isn't ready before Q4 hits, you're handing enquiries to competitors who are.
This checklist is for Portsmouth business owners who want to make sure their website is working as hard as possible heading into the busy season.
Performance & Technical
- Run your site through Google PageSpeed Insights — aim for 90+ on mobile. Anything below 70 needs attention before October.
- Check your Core Web Vitals in Google Search Console. LCP under 2.5s, CLS under 0.1, INP under 200ms.
- Confirm your site loads correctly on the latest iOS and Android browsers — not just Chrome on desktop.
- Check all forms are working — contact forms, quote requests, booking tools. Test them yourself from a fresh browser window.
- Confirm your SSL certificate is valid (the padlock in the browser). Expired certificates kill conversions instantly.
- Check that redirects are in place for any old URLs — especially if you've changed your site structure in the past year.
Content & Messaging
- Is your homepage headline clear about what you do, who for, and where? If a stranger couldn't understand it in 5 seconds, rewrite it.
- Are your services and pricing up to date? Q4 is a bad time for visitors to find outdated information.
- Do you have a specific Q4 or Christmas offer? If so, it needs a landing page — not just a homepage mention.
- Are your opening hours (and any holiday closures) clearly visible — especially if you run a physical location?
- Does every key page have a clear call to action? One per page, obvious, above the fold on mobile.
Local SEO
- Is your Google Business Profile updated with current hours, services, photos, and a Q4 post?
- Are your NAP details (Name, Address, Phone) consistent across your website, GBP, and any directories?
- Do you have at least 10 recent Google reviews? If not, now is the time to ask happy customers — before the busy season, not during it.
- Have you published any location-specific content in the last 3 months? A blog post targeting "[your service] Portsmouth" signals to Google that you're active and relevant.
eCommerce (if applicable)
- Test your checkout flow end-to-end — from adding to basket to order confirmation email. Every step.
- Check your stock levels and delivery messaging are accurate. Misleading delivery times in November lose you sales and reviews.
- Do you have abandoned cart emails set up? This alone can recover 5–15% of lost sales.
- Is your site ready to handle a traffic spike? Check with your host that your plan can handle 3–5x normal traffic without going down.
- Have you planned your Black Friday / Cyber Monday promotions and built landing pages in advance?
Trust & Conversion
- Are your most relevant testimonials and case studies visible on your homepage and key service pages?
- Is there a clear, easy way to contact you — phone number clickable on mobile, a contact form that actually works, a response time expectation set?
- Do you have social proof near your CTAs? Even a single review next to a "Get a Quote" button can increase clicks significantly.
- Is your privacy policy and cookie notice up to date? Outdated legal pages are a quiet trust killer.
What to Do if You Spot Problems
The window to fix things properly before Q4 is now — not September. Design and development work takes time, and any new pages need a few weeks to be indexed and ranked by Google before they'll bring in organic traffic.
