Website Platform Decision Matrix and Checklist
A decision matrix makes a platform choice explainable to a co-founder, board or agency. Score each shortlisted platform on eight criteria, weight them for your stage, and keep the reasons next to each score. The free spreadsheet does the maths; this page explains the method.
Evidence labels on this page. Sourced comes from the platform’s own documentation or pricing page, checked October 5, 2026. Editorial is ShoutEx judgement. Not yet tested means the check is on our published test plan with no result yet. Method: how we evaluate platforms.
How do you choose a website platform with a decision matrix?
Shortlist two to four platforms, score each from 1 to 5 on eight criteria using written anchors, set weights that add up to 100% for your stage, and multiply. The highest weighted score is your provisional choice. Then test it by building one real page. The decision matrix spreadsheet does the calculation and keeps notes per score.
| Criterion | Measures | 1 | 3 | 5 |
|---|---|---|---|---|
| Launch speed | Weeks to a live, usable site | Months; needs developers | A few weeks with some help | Days, by the team |
| 3-year cost | Build, fees, seats, maintenance | Highest of the shortlist | Middle | Lowest of the shortlist |
| SEO controls | Titles, URLs, redirects, schema, rendering | Basics only, some fixed | Most controls, some code | Full control without code |
| Content operations | Publishing, CMS size, workflow | Few editors, small CMS | Works with limits | Large CMS, roles, workflow |
| Design control | Layouts without a developer | Theme limits | Some freedom | Full visual control |
| Integrations | CRM, forms, analytics, custom | Few, mostly embeds | Main tools covered | Large ecosystem or custom |
| Maintenance burden | Updates, security, hosting | Heavy, needs developers | Some monthly work | Platform handles it |
| Ownership | Export, hosting choice, lock-in | No export | Partial export | Full code and data |
How should you weight the criteria?
Weights reflect what matters at your stage. Before launch, speed and low upkeep matter most. At seed, SEO and content operations grow in weight. At scale, integrations and content operations lead. Start from a preset and change no more than three weights, then write down why.
| Criterion | Idea | Seed | Scale |
|---|---|---|---|
| Launch speed | 20 | 10 | 5 |
| 3-year cost | 15 | 15 | 10 |
| SEO controls | 15 | 20 | 20 |
| Content operations | 10 | 15 | 20 |
| Design control | 15 | 10 | 10 |
| Integrations | 5 | 10 | 15 |
| Maintenance burden | 15 | 10 | 10 |
| Ownership | 5 | 10 | 10 |
What does a finished matrix look like?
Northwind, a fictional seed-stage SaaS, shortlisted WordPress, Webflow and Framer. With seed weights, WordPress scored 4.25, Webflow 3.95 and Framer 3.75. The scores were close, so the team built one page on WordPress and Webflow before deciding. The matrix narrowed the choice; the hands-on page settled it.
| Criterion | Weight | WordPress | Webflow | Framer |
|---|---|---|---|---|
| Launch speed | 10% | 4 | 4 | 5 |
| 3-year cost | 15% | 4 | 3 | 4 |
| SEO controls | 20% | 5 | 4 | 4 |
| Content operations | 15% | 5 | 4 | 3 |
| Design control | 10% | 3 | 5 | 5 |
| Integrations | 10% | 5 | 4 | 3 |
| Maintenance burden | 10% | 2 | 5 | 5 |
| Ownership | 10% | 5 | 3 | 1 |
| Weighted score (out of 5) | 100% | 4.25 | 3.95 | 3.75 |
What should you check before you commit?
- The person who will edit the site has built one page on the platform.
- Must-have requirements are confirmed on the plan you will buy.
- Three-year cost is estimated; see how much a startup website costs.
- SEO basics are confirmed; see the SEO comparison.
- Export and exit options are understood.
- A URL list exists if you are replacing a site; see the migration SEO checklist.
Decide with weights, confirm with a build.
A matrix narrows the field. One real page on the shortlisted platform makes the final call.
