The foundation everything rests on. If Google can't crawl, index, and load your site quickly, no amount of content or links will move the needle.

HTTPS enforced on all pages — no mixed content warnings
Every page must serve over HTTPS. Mixed content (HTTP images or scripts on an HTTPS page) triggers browser warnings and undermines trust signals. Check with whynopadlock.com.
SSL certificate is valid and set to auto-renew
An expired SSL certificate causes Google to flag your site as "Not Secure" and rankings drop fast. Use Let's Encrypt with auto-renewal, or set a calendar reminder 30 days before expiry. Check your current expiry at sslshopper.com.
Site verified in Google Search Console with XML sitemap submitted
GSC is your direct line to Google. Submit your
sitemap.xml at GSC › Sitemaps and regenerate it whenever you add, remove, or restructure key pages.robots.txt present and not blocking important pages
Check
yourdomain.com/robots.txt. A misconfigured robots.txt that accidentally disallows crawling of your key pages is one of the most common — and damaging — SEO mistakes. Never disallow your entire site in production.No important pages returning 4xx or 5xx errors
Crawl with Screaming Frog (free up to 500 URLs) or check GSC › Coverage. Fix broken internal links and 301-redirect deleted pages to relevant alternatives to preserve link equity.
Canonical tags correctly set on all pages — self-referencing where no duplication exists
Each page needs a
<link rel="canonical">. For duplicate or near-duplicate content, canonicals must point to the preferred version to consolidate ranking signals and prevent keyword cannibalisation.URL structure is clean, lowercase, and uses hyphens not underscores
Good:
/services/seo. Bad: /Services/SEO_Services?id=12. Clean URLs are easier for Google to parse, users to remember and share, and naturally earn better anchor text when linked to.LCP (Largest Contentful Paint) under 2.5 seconds
LCP measures how fast the main content loads. Improve it by preloading your hero image with
<link rel="preload">, serving images as WebP, using a CDN, and optimising server TTFB. Test with PageSpeed Insights on real mobile and desktop.CLS (Cumulative Layout Shift) under 0.1
Layout shifts happen when images load without explicit dimensions, or fonts cause reflow. Set
width and height on all <img> elements and use font-display: swap on custom fonts to prevent layout jumps.INP (Interaction to Next Paint) under 200ms
INP replaced FID as a Core Web Vital in March 2024. It measures responsiveness to all user input. Fix it by deferring non-critical JavaScript, breaking up long tasks on the main thread, and reducing third-party script bloat.
All images served as WebP with lazy loading on below-fold images
WebP is 25–35% smaller than JPEG/PNG at equivalent quality. Add
loading="lazy" to all below-fold images. Preload the hero/LCP image specifically to avoid it being discovered late by the browser.Static assets served via CDN (Cloudflare or equivalent)
Cloudflare's free tier is sufficient for most SMBs. A CDN dramatically reduces TTFB by serving assets from servers close to the user — essential when serving both US and EU audiences simultaneously.
Site passes Google's Mobile-Friendly Test — no tap target or font-size errors
Google uses mobile-first indexing — it primarily crawls and ranks the mobile version of your site. No tap target errors, no text too small to read, fully usable at 375px viewport width without horizontal scrolling.
Organization schema implemented in JSON-LD on the homepage
Add an
Organization schema with name, URL, logo, address, social profiles, and contact info. This validates your business identity in Google's Knowledge Graph and can trigger branded rich results in SERPs.All schema validated in Google's Rich Results Test — no errors or warnings
Schema errors silently prevent rich results from appearing. Test every templated page type at search.google.com/test/rich-results and fix all warnings before and after launch.

Every page has a unique title tag under 60 characters with the primary keyword near the front
The title tag is the single most important on-page ranking signal. Front-load the keyword, add your brand name at the end, keep under 60 characters to avoid truncation in SERPs. No two pages should share the same title.
Every page has a unique meta description under 160 characters with a differentiator and soft CTA
Meta descriptions don't directly affect rankings but do affect click-through rates. Include a differentiator ("US & EU", "free audit") and a soft CTA. No duplicates across pages — Google will often rewrite them if they're missing or low quality.
Search intent matched — page content type aligns with what top-ranking pages deliver for the keyword
If the top 10 results for your keyword are all listicles, writing a product page won't rank. Match format to intent: informational (blog post), commercial (service page), transactional (product/booking page). Check the SERPs before writing anything.
Each page has exactly one H1 containing the primary keyword — distinct from the title tag
One H1 per page. It should front-load the target keyword and be different from the title tag — the title tag ranks, the H1 converts. Never copy-paste the title tag into the H1.
H2–H3 headings structure the page logically with secondary keywords
Headings create a clear content hierarchy for both Google and screen readers. Write them for humans first. Subheadings also help users scan and find what they need without reading every word.
Service / landing pages are at least 600 words — 900–1,400 is optimal
Thin content (under 300 words) is a common reason pages don't rank. Every word should answer a genuine question a prospective client would have before they decide to contact you.
No duplicate content across pages — each page targets a distinct keyword and topic
Identical or near-identical content across multiple pages confuses Google about which to rank. Write unique content per page or use canonical tags where duplication is unavoidable.
All images have descriptive, keyword-relevant alt text
Alt text serves two purposes: SEO and screen reader accessibility. Use descriptive text — not "image1.jpg". Decorative-only images can have empty alt attributes; meaningful images must not.
Each service page has 2–4 internal links with keyword-rich, descriptive anchor text
Internal links pass authority and help Google understand the relationship between pages. Use descriptive anchor text ("ongoing website care") — never "click here" or "learn more". One link per destination per page body is sufficient.
No orphan pages — every page is linked to from at least one other page
Orphan pages can't be discovered by Googlebot following internal links. Run a crawl with Screaming Frog and identify any pages with zero internal links pointing to them.
BreadcrumbList schema on all service and blog pages — labels match visible breadcrumbs exactly
Breadcrumb schema enables breadcrumb display in SERPs, improves CTR, and reinforces site hierarchy. The schema text must be character-for-character identical to the visible breadcrumb on the page — any mismatch disables the rich result.
FAQPage schema on service pages — Q&A text matches visible FAQ content exactly
FAQPage schema can trigger accordion rich results in SERPs, expanding your SERP footprint substantially. The question and answer text in schema must exactly match what's visible on the page — Google verifies this before awarding the rich result.
Hreflang tags set on all pages targeting multiple regions (en-us, en-gb, x-default)
If you're targeting both US and UK/EU audiences, hreflang prevents Google from showing the wrong regional variant in search results. All tags must be reciprocal — each page must reference all other regional variants, including itself.

Keyword research completed for every target service and landing page
Use GSC, Ahrefs Free, or Semrush to identify a primary keyword per page with measurable volume and attainable difficulty, plus 2–4 secondary keywords. One page, one primary keyword — targeting five at once splits focus and dilutes every signal.
Keyword cannibalisation audit run — no two pages targeting the same primary keyword
When two pages compete for the same keyword, Google splits ranking signals between them and often ranks neither well. Audit with GSC or Ahrefs, then merge, redirect, or differentiate cannibalising pages before building new content.
Topic cluster mapped for each core service — pillar page supported by related blog posts
A pillar page (your service page) surrounded by cluster content (blog posts on related subtopics, all linking back to the pillar) builds topical authority. Google rewards sites that cover a topic deeply. Breadth without depth doesn't rank.
Blog or resources section publishing at minimum 2 quality posts per month
Consistent publishing signals an active, authoritative site. Quality always beats frequency — one genuinely useful 1,200-word post beats four thin 300-word posts. Every post must target a real search query with measurable volume and clear searcher intent.
All published content is human-written or thoroughly human-edited — not raw AI output
Google's Helpful Content system targets mass-produced, low-quality AI content. Use AI for research and outlines — but every published article must be reviewed, substantially edited, and improved by a human subject-matter expert before going live.
E-E-A-T signals present: author bylines, credentials, real case studies, specific results
Experience, Expertise, Authoritativeness, Trustworthiness. Named authors with bios on articles, links to real project outcomes with specific numbers, and an About page that establishes genuine credentials. These are non-optional for service businesses competing in Google's quality scoring.
Content gap analysis run against top 3 competitors — missing topic areas identified and prioritised
Use Ahrefs Content Gap or Semrush Keyword Gap to find keywords your competitors rank for that you don't. These are pre-qualified opportunities — someone has already proven the search volume and intent exists. Prioritise by business relevance first, then volume.
Content pruning audit completed — thin, outdated, or zero-traffic pages removed or consolidated
Low-quality pages drag down your overall site quality score. For pages with zero organic traffic in 12 months: update with genuinely useful content, consolidate similar pages with a 301 redirect, or remove and redirect if there's no realistic path to value.

Full backlink audit completed — toxic or spammy links identified and disavowed
Bad links (paid links, link farms, PBNs, irrelevant spam) can trigger a Google manual penalty. Audit with Ahrefs or GSC, flag suspicious domains, and submit a disavow file via GSC if you've inherited bad links from a previous agency or old site history.
No paid links, link farms, or PBN links pointing to the site
Paid link schemes violate Google's guidelines and risk a manual action that removes you from search results entirely. Zero tolerance. If anyone is offering "guaranteed rankings" through link packages, walk away.
Broken backlinks identified and reclaimed via 301 redirects
When pages are renamed or deleted, external links to those old URLs become 404s — the link equity is lost. Use Ahrefs or GSC to find pages with inbound links returning 404, then 301-redirect them to the nearest relevant live page.
At least 5 quality editorial backlinks from relevant, trusted domains
Contextually placed, editorially given links from industry-relevant sites carry far more weight than dozens of generic directory listings. Five strong editorial links from trade publications outperform 50 from random directories.
Outreach plan in place — guest posts, partnerships, HARO/Qwoted for digital PR coverage
Sustainable link building is earned, not bought. Identify 10 sites in your industry to contribute to or partner with. HARO and Qwoted connect you with journalists needing expert quotes — a high-ROI source of editorial links from trusted publications.
Competitor link gap analysis completed — target domains for outreach identified
Sites linking to your top competitors but not to you have already shown willingness to link to businesses like yours. Use Ahrefs Link Intersect or Semrush Backlink Gap to build a qualified, warm outreach list rather than cold-prospecting from scratch.
Unlinked brand mentions monitored and converted to backlinks where possible
When someone mentions your brand without linking to you, that's a low-effort link opportunity — they already know you exist. Set up Google Alerts or Ahrefs Alerts for your brand name, then email the author requesting they add the link.

GBP claimed, verified, and fully completed — category, description, hours, services, photos
GBP is the single most important local SEO asset. Claim it at business.google.com, verify by postcard or phone, and fill every field. Your primary category is the strongest local ranking signal — choose the most specific one that accurately describes your core service.
GBP has at least 5 real photos and is updated with posts at least twice per month
Profiles with photos receive 42% more direction requests and 35% more click-throughs (Google data). Upload real photos — not stock. Regular GBP posts signal an active, legitimate business and provide additional keyword-rich content in the local pack.
NAP (Name, Address, Phone) is character-for-character identical across all online listings
Inconsistent NAP confuses Google's local algorithm. "St" vs "Street", different phone number formats, or a slightly different business name all count as inconsistencies. Audit with BrightLocal or Semrush Listing Management and fix every mismatch.
Listed on major aggregators (Yelp, Apple Maps, Bing Places) and 10+ industry-relevant directories
These aggregators feed data to hundreds of smaller directories. Bing Places is ignored by most businesses but captures 6–10% of search share. Industry-specific directories (Clutch for agencies, Houzz for home services) carry more weight than generic ones.
Active process in place to request Google reviews — targeting 10+ reviews with 4.0+ average
Reviews are a confirmed local ranking factor. Create a direct GBP review link from your GBP dashboard and send it to every client after project completion. Spread review acquisition over time — a sudden spike triggers Google's spam filter.
All Google reviews responded to within 7 days — personalised, not copy-pasted
Google has confirmed that responding to reviews improves local ranking. Respond to positive and negative reviews with specific, genuine responses. Identical copy-paste replies are a red flag to both Google's quality signals and potential customers reading them.
LocalBusiness schema on homepage and contact page — NAP, geo-coordinates, hours, service area
JSON-LD LocalBusiness schema with your NAP,
geo coordinates, opening hours, and areaServed reinforces local signals in the Knowledge Graph. Validate at Google's Rich Results Test before publishing to confirm no errors.

GA4 property is active, correctly configured, and receiving data on all pages
Universal Analytics was permanently retired by Google on 1 July 2024. GA4 is now the only standard. Verify it's firing on every page with no gaps using GA4 DebugView or Google Tag Assistant. Check your data stream settings and confirm events are flowing.
Google Tag Manager deployed — all tracking managed through GTM, not hardcoded scripts
GTM centralises all tracking in one place, loads asynchronously (no page speed penalty), and lets you add or modify tags without a developer deploy cycle. Remove all hardcoded GA4 snippets and pixels once GTM is live to avoid firing tags twice.
Key conversion events configured in GA4 — form submits, phone clicks, free audit requests
Pageviews alone tell you nothing useful. Mark your high-intent business actions as conversions in GA4: contact form submissions, phone click events, free audit requests, booking completions. These become the north star for all SEO reporting and campaign decisions.
GA4 linked to Google Search Console for combined organic performance data
Linking GA4 and GSC lets you see which queries, pages, and devices drive organic traffic and which ones convert — in one view. Without this link, you're looking at two incomplete pictures instead of one complete one. Link it in GA4 › Admin › Product Links.
UTM parameters applied consistently to all campaign URLs — email, paid, social
Without UTMs, GA4 often misclassifies campaign traffic as Direct. Use a shared naming convention:
utm_source, utm_medium, utm_campaign. A shared UTM builder spreadsheet prevents inconsistent casing and naming across team members.Rank tracking configured for primary keywords — monitored weekly with alerts for significant drops
GSC shows impressions and average position but not historical rank trends. Use Ahrefs, Semrush, or SERPWatcher to track your 20–30 most important keywords weekly. Set automated alerts so rank drops are caught before they cause meaningful traffic loss.
GA4 IP anonymisation enabled and consent mode configured for EU/GDPR compliance
Under GDPR, collecting identifiable IP addresses without explicit consent is a violation. Enable IP anonymisation in GA4 data settings and implement Google Consent Mode v2 for EU visitors. For EU-only operations, consider a privacy-native alternative like Fathom or Plausible.
Monthly SEO report covers organic traffic, keyword movements, conversions, and next actions
A good SEO report doesn't just show numbers — it explains what changed, why, and what you're doing about it. Track organic sessions, goal completions, top organic landing pages, and keyword position changes month-over-month. Numbers without interpretation are noise.

A note on SEO timelines
Completing this checklist puts your site in a strong technical and strategic position — but SEO is not instant. Depending on your market's competition and your site's starting point, meaningful organic traffic growth typically begins at 3–6 months. Competitive niches take longer. Anyone promising page-one rankings in 30 days is misleading you. What this checklist gives you is the right foundation — the rest is consistent execution over time.
