Web Loading Speed: The SEO Factor Most Granada SMEs Ignore

Core Web Vitals: what they are and why Google measures them

Since 2021, Google uses three metrics called Core Web Vitals as ranking factors. They're not technical jargon — they measure exactly what users feel when they visit your site:

• LCP (Largest Contentful Paint): how long it takes for the main content to appear. Ideal: under 2.5 seconds. Over 4 seconds is considered a serious problem by Google.
• INP (Interaction to Next Paint): how quickly the page responds when users click something. Ideal: under 200ms. A slow site here feels 'frozen'.
• CLS (Cumulative Layout Shift): how much content moves while loading. That button that shifts just as you're about to click — that's high CLS, and Google penalises it.

How to measure your site speed right now (free)

Go to PageSpeed Insights (pagespeed.web.dev) and enter your URL. In under 30 seconds you get a score from 0 to 100, your specific Core Web Vitals metrics, the specific causes of detected issues, and improvement suggestions ordered by impact.

The most common causes of slow SME websites

• Unoptimised images: uploading a 5MB photo directly from your phone is the most common and costly mistake. A WebP image can weigh 10x less with the same visual quality.
• Cheap shared hosting: 1-2€/month plans share a server with hundreds of sites. During peak hours, performance drops dramatically.
• Too many WordPress plugins: each plugin adds code the browser must load. A WordPress site with 40 active plugins can take 8-10 seconds to load.
• No browser cache: if every visit downloads all resources from scratch, the site will always be slow for returning visitors.

Frequently asked questions about website speed and SEO in Granada

What score should my website have on Google PageSpeed Insights?

The target is to exceed 90 out of 100 on the mobile analysis, which is the most demanding and is the one Google uses as its primary reference since 2023. A score between 50 and 89 indicates improvable issues. Below 50 there are serious problems that directly affect ranking and conversion rates. For a small business in Granada, achieving 90+ on mobile is achievable with a well-built website, optimised images and adequate hosting.

Why does page load speed directly affect Google rankings?

Since 2021, Core Web Vitals have been official ranking factors. But there is a more direct chain: a slow website has a higher bounce rate (the user leaves without interacting), and Google interprets an immediate bounce as a signal that the page does not satisfy the search intent. The result: a drop in positions. Additionally, 53 % of users abandon a website that takes more than 3 seconds to load, reducing actual traffic regardless of ranking.

What are the most common causes of slowness in small business websites?

The most frequent ones are: uncompressed images not converted to WebP (a 5 MB photo where there should be 80 KB), low-tier shared hosting that cannot serve the website quickly under real load, too many WordPress plugins loading on every page whether used or not, and the absence of caching. A very common mistake on business websites in Granada is using photos taken with a smartphone and uploading them without any processing.

How can I improve my website's speed without rebuilding it entirely?

The actions with the greatest impact and lowest cost are: compressing and converting all images to WebP, enabling server-side caching, switching to better-performing hosting if the current one is low-tier, and removing plugins that are not actively used. On most WordPress websites, these four actions can improve the PageSpeed score by 30 to 50 points without touching the design. For cases where the problem is the technical architecture of the website, a partial redesign may be necessary.
