The short answer
A redesign fixes how your site behaves. SEO fixes whether Google has a reason to show it. If your pages load slowly, break on a phone, or make people bounce before they call, that is a design problem. If your pages are fast and clean but nobody finds them, rebuilding them prettier will not move you.
Most Austin service businesses we talk to have the second problem and get sold the first one. That is an expensive way to stay invisible.
What a redesign actually fixes
A redesign fixes measurable things, and Google publishes the numbers it measures them against. Google's Core Web Vitals documentation sets three thresholds: your Largest Contentful Paint should happen within the first 2.5 seconds of the page starting to load, your Interaction to Next Paint should be under 200 milliseconds, and your Cumulative Layout Shift should be under 0.1.
| Metric | Good | What it measures |
|---|---|---|
| Largest Contentful Paint | Under 2.5s | How long until the main content appears |
| Interaction to Next Paint | Under 200ms | How fast the page responds when tapped |
| Cumulative Layout Shift | Under 0.1 | How much the page jumps around while loading |
Those thresholds are assessed at the 75th percentile of page loads, not the average. Google's web.dev documentation explains why: the 75th percentile means a majority of visits to the page hit the target, and it resists being skewed by a handful of outliers. A site that is fast on your office wifi and slow on a phone in a truck fails at the 75th percentile.
The other thing a redesign fixes is the phone. Google's documentation on mobile-first indexing is direct about this: Google uses the mobile version of a site's content, crawled with the smartphone agent, for indexing and ranking. The desktop version of your site is not what gets judged. If your site was built before that shift and nobody has looked at it on a phone since, that is a real reason to rebuild, and it is the case where our website design work pays for itself.
What a redesign does not fix
A redesign does not give Google a new reason to rank you. Google's page experience documentation says plainly that there is no single page experience signal, and that Google Search "always seeks to show the most relevant content, even if the page experience is sub-par." Speed is a tiebreaker between pages that both answer the question. It is not a substitute for answering it.
Google's own SEO Starter Guide is blunter still. It says creating content that people find compelling and useful will likely influence your website's presence in search results more than any of the other suggestions in that guide. That sentence is Google telling you the pages matter more than the wrapper.
A redesign also does nothing for the map pack, which is where most of your calls come from. Google Business Profile's help documentation lists three factors behind local ranking: relevance, distance, and prominence. Your website feeds relevance. It does not change how far you are from the searcher, and it does not make you better known. Google is also explicit that there is no way to request or pay for a better local ranking. That work is local SEO, and a new homepage does not touch it.
The risk nobody mentions when they sell you a redesign
If your redesign changes your URLs, you are doing what Google calls a site move, and Google's documentation tells you to expect temporary fluctuation in site ranking during the move. For a medium-sized site, Google says it can take a few weeks or more before it starts showing the new URLs instead of the old ones.
That is survivable if it is planned. Google confirms that 301 and other permanent redirects do not cause a loss in PageRank, so a redesign with every old URL mapped to its new home recovers. A redesign where the old URLs simply stop existing does not. We have picked up Leander and Cedar Park contractors whose new site launched on a Friday and whose phone stopped ringing by the following Wednesday, because nobody redirected anything.
Ask any web designer quoting you a rebuild one question: what happens to my existing URLs. If the answer is vague, that is your answer.
How to check which one you need, in about ten minutes
Run your homepage and your busiest service page through Google's PageSpeed Insights. Read the field data section, not the lab score at the top. Google's own documentation explains the difference: lab data is collected in a controlled environment and may not capture real-world bottlenecks, while field data is useful for capturing true, real-world user experience. That field data comes from the Chrome User Experience Report and covers trailing 28-day periods, which means it is your actual customers on their actual phones.
If the field data fails the thresholds in the table above, you have a design and performance problem worth spending money on. If it passes and your phone still is not ringing, the problem is that Google has no reason to show pages that work fine. That is a content and local search problem.
Then check the timeline you are being promised. Google's SEO Starter Guide says some changes might take effect in a few hours while others could take several months, and Google's guidance on hiring an SEO states that no one can guarantee a #1 ranking on Google. Anyone selling you either a redesign or a campaign on a fixed ranking promise is selling something Google says does not exist.
Frequently asked questions
Will a new website automatically improve my Google rankings?
No. A new website can improve the page experience signals Google measures, but Google's page experience documentation states that Search always seeks to show the most relevant content even when page experience is sub-par. If the old site ranked on the strength of its content, a redesign that keeps the same content and the same URLs is roughly ranking-neutral by itself.
Can a website redesign hurt my rankings?
Temporarily, yes, if URLs change. Google's site move documentation says to expect temporary fluctuation in ranking during the move and that a medium-sized site can take a few weeks or more to be fully reprocessed. Permanent 301 redirects from every old URL protect you, because Google confirms those do not cost PageRank.
How fast does my site actually need to be?
Google's published thresholds are Largest Contentful Paint under 2.5 seconds, Interaction to Next Paint under 200 milliseconds, and Cumulative Layout Shift under 0.1, measured at the 75th percentile of real page loads. Meeting those is the bar. Going far beyond them is not where the next call comes from.
My site is fine and I still get no calls. Now what?
Then the gap is visibility, not the website. For a local service business that usually means the Google Business Profile, the reviews, and whether you have real pages for the cities you serve. Those are the levers behind relevance and prominence in Google's local ranking documentation, and none of them are design work. Start with a look at how you currently rank across the Austin metro.
