The Ultimate Website SEO Checklist: 5 Steps to Launch Your Visibility

If there’s one branch of digital marketing we love above all at Référenceur, it’s SEO. Think of it as the rocket engine for brands and businesses: SEO (search engine optimization) helps you climb the search results and stand out from the competition.

But as you can imagine, with heavyweights like Google and Bing in charge, “competition” also means “know your stuff, or the algorithm that ranks you will make you pay.” In other words, become an expert in space exploration, because this mission won’t be easy.

Google doesn’t mess around, and neither does Bing. Good news: when it comes to SEO, neither do we. Follow the commander. Here’s our complete website SEO checklist, with every point you can’t afford to skip.

SEO: Seriously Exciting Opportunities Search Engine Optimization

Let’s start with a little context, and some attitude.

We often describe SEO as a growth engine for a business. That may sound like a stretch when you consider everything that determines a company’s long-term success, but trust us, it isn’t much of one. And the fact that the E in SEO stands for “engine” may not be a total coincidence.

The point is, SEO isn’t a hobby you dabble in now and then. It’s a full-on space race that takes skill, stamina, knowledge, investment, and time (lots of time).

It’s also a demanding field that could change the face of your business. SEO is a spirited but friendly conversation between you, Google, and its buddies, held through your website. And it’s a goldmine of opportunities for anyone who pays close attention to what the other side is trying to say.

Ready to board an SEO adventure that’s as exciting as it is rewarding? Let’s talk.

The SEO Checklist at a Glance

• Check your site’s foundations (HTTPS, CMS, URLs, analytics, and page hierarchy)
• Get your keywords under control
• Optimize your pages and content (title tags, meta descriptions, and varied formats)
• Don’t upset Google (indexing, errors, speed, and mobile-friendliness)
• Stack the odds in your favor (backlinks, link attributes, internal links, social media, Google Business Profile, and KPIs, because it’s always about KPIs)

And that’s it, end of article.

Just kidding. Launching a machine as powerful as SEO obviously takes much more precise procedures. Skip them, and a crash is all but certain.

So before you charge headfirst into battle, arm yourself with a solid strategy and check your structure.

1. Check Your Site’s Foundations

Whether your site is brand new or a relic from the early days of the internet (in which case a website redesign is probably in order), you first need to make sure the foundation is solid.

Tick every box below before you start the engine, because things are about to get loud, and SEO is running the show:

Set Up HTTPS

Websites collect more visitor data than ever, and keeping that data safe has to come first. That’s why HTTPS belongs at the top of your priority list. It encrypts the connection between your site and its visitors, and it tells them your site is safe to browse. Google has also used HTTPS as a lightweight ranking signal since 2014, and browsers flag pages without it as “Not secure.”

Use a CMS to Manage Your Content

If there’s one tool that makes SEO easier, it’s a content management system (CMS). A CMS smooths the journey and saves time on every task. The most popular by far is WordPress, which proudly sits at the top of the list of most-used CMSs and is very SEO-friendly.

Other platforms such as Shopify, Joomla, and Drupal also hold their own. At Référenceur, a French-speaking SEO agency based in Belgium and Luxembourg, we’re ready to fly the ship, whatever its frame.

Optimize Your URLs

A URL is a bit like your car’s license plate, except your site gets one for every page. Even better, it’s what lets the web find a precise location on your site.

Needless to say, getting your URLs right is important essential. If you sell bikes and the URL for your product page is www.example-bikeshop.com/electricbikesredpineapple (yawn), it won’t bring in many visitors from search engines, unless you happen to sell a world-famous model called electricbikesredpineapple.

At best, it’s an eyesore. Go for something like www.example-bikeshop.com/bikes/electric/red-pineapple instead. Google is meticulous, and it will thank you for it. (More tips in our guide to SEO-friendly URLs.)

Track Performance and Traffic With the Right Tools

Let’s say it up front: slow and steady wins the race, but only once you’re ready to measure your performance. That’s taking some liberties with the old fable, but it fits the times.

Performance indicators matter more every year, for one simple reason: what you can measure, you can adjust. If you don’t measure, you can’t improve.

To get there, Google kindly gives us three free analytics tools that have caused more than a few premature bald spots: Google Analytics 4 (GA4), Google Search Console, and Google Tag Manager.

With these three tools of mass measurement, you’ll know your visitors’ every move.

Build a Clear Page Hierarchy

Google’s crawler, your website’s closest friend, doesn’t like wasting time when it drops by. It will always be there for you, but its address book is as long as a round trip to the moon, and it plans to visit everyone. So the faster you let it in, the more it will appreciate it.

The best way to make its visit easy is to show it that the most important rooms (like the bathroom) are easy to reach, and that it can get from one room to the next without getting lost (like a quick hand wash on the way out). Better yet, link every room to the others and put a name plate on each door, and Google will leave with a big smile.

Google, your page hierarchy, and your website: a love triangle that isn’t ending anytime soon.

2. Get Your Keywords Under Control

Your keyword list is like the shopping list you need when you head to the grocery store. Without it, you buy random stuff and get home having forgotten half of what you actually needed.

So take the time to write it, walking through the whole house to make sure nothing’s missing. It’s hard at first, but with practice you get better at it, until you can shop with the list in your head.

In other words, your site’s keyword list is the foundation that guides everything you do. It also lets you measure your results and rankings later on. To build it, look at two things:

• Your business: what you sell, the services you offer, and where you want to be visible. In short, the terms you want to show up for when someone types a query into Google.
• Search volume: optimizing for keywords nobody actually searches for rarely pays off. Sometimes a small tweak makes all the difference. You might assume people search for “Google visibility specialist” when “SEO expert” actually gets far more searches, or the other way around. Once you know, you can adjust, get better results, and build the right strategy.

Competition, Adaptation, Search Intent, and Keyword Value

Those are the watchwords of an effective keyword strategy. Keep in mind that your list has to evolve as these factors change.

When it comes to competition, remember that your competitors in search aren’t necessarily your competitors down the street.

If you want to rank for electric bikes, the shop next door may not be a real digital competitor if it has no web strategy, at least for now. An online store based in another state, or even another country, could be, if it decides to target your market.

If any part of your SEO strategy needs to keep evolving, it’s your keyword list and everything tied to it. Just like your shopping list changes with your needs.

We get it: building a list of relevant keywords is hard. But we love it. Let us help.

3. Optimize Your Pages and Content

Page optimization and content writing are the most visible, hands-on parts of SEO. Think of them as the bodywork of your ship. And “bodywork” means “first impression,” which means “make it look good, because you won’t get a thousand chances.” Time to bring out the custom rims and chrome mirrors. Just don’t overdo it.

Polish Your Titles and Avoid Duplicates

Several issues can hurt your titles, and your SEO along with them, so use an SEO crawler to find them: titles that are too long, duplicate titles, and missing titles.

Fixing them should become your new mission. Write strong titles that put your main keyword as close to the beginning as possible, using synonyms where they help. Vary your titles and subheadings, and build a clean heading structure: one H1, then H2s, H3s, and so on down to H6. (HTML stops at H6, which spares us all an H13.)

In short: optimized, consistent title tags and headings. Our guide to title tag SEO goes deeper.

Write Strong Meta Descriptions

Meta descriptions. Now there’s an interesting topic. Not because they’re the most decisive factor in SEO history (they don’t directly affect rankings), but because a good one can win you the click.

The meta description is the snippet of text that can appear under your page’s title in search results. It isn’t required, and if you leave it blank, Google won’t show an empty space. It will write one on its own, pulling text from your page. The trouble is, Google has a lot on its plate, and the automatic version isn’t always a good fit.

So you’re better off writing your own. Friendly advice. Like a fussy old uncle, Google may still decide to rewrite it when it thinks another passage better matches a search. There’s no penalty for that, but a clear, compelling description gives you the best shot at controlling your snippet and earning the click.

Mix Up Your Content

Look closely at this article and you’ll notice we’ve worked to make it easy on the eyes. Because endless walls of text with no breathing room? Enough already. And Google is smart enough to notice. Yes, artificial intelligence is no joke.

So adding images and videos to give readers (and Google’s crawler) a break is a bit like handing reading glasses to someone squinting at a screen all day.

Images and videos on a page are good. Optimizing them for search is even better. Google reads file names, alt text, and the text around your media. Nothing gets past it.

The upside: optimized media can earn you visibility in Google Images and video results. That can make a real difference against the competition. (See our guide to image SEO.)

It may sound a little crazy, but optimization is honestly our idea of fun. Like, really. Say hello.

4. Don’t Upset Google

Google is loyal and promises to always be there for you, but it can also be fickle. In other words, Google is the friend you need to treat well and never disappoint. In return, it should reward your online presence handsomely.

Check Indexing

Start your car with the parking brake on and you won’t get far. Obvious, right? Same with Google. If your robots.txt file or a stray noindex tag blocks your content, Google can’t crawl or index it. Check the Page indexing report in Google Search Console, make a quick fix, and you’re good to go.

Find Errors and Broken Links

Another thing Google can’t stand is wasted time. Remember, Uncle Google is a busy guy. If it keeps hitting a wall when it tries to crawl your pages, or worse, finds duplicate content, or worse still, wears itself out landing on empty pages, it won’t be pretty. Don’t overlook this one: our technical SEO audit checklist helps you catch these issues.

Check Your Site Speed

Your ship’s paint job and overall design make it look sharp and let you show off. Add a few cool features, rock-solid reliability, and good tires, and it seems ready to race. But one thing is still missing: acceleration and top speed.

Without them, forget shooting for the moon. Remember, Google doesn’t have time to waste, and neither do your visitors. So compress heavy files, limit iframes, trim and defer CSS and JavaScript, lighten the load on your server, and keep an eye on your Core Web Vitals. Our website speed optimization checklist walks you through it.

Make Sure Your Site Works on Mobile

Google’s crawler is a lot like you, me, and the billions of people hooked on the web, except it has made up its mind: it now crawls and indexes sites primarily as a smartphone user. If the mobile version of your site is as complicated as a Rubik’s Cube, plenty of people won’t be laughing. So to avoid frustrating Google and your visitors, make your site fully responsive.

The challenge is stepping back while you build a site. Most of the work happens on a computer with a screen far too big to fit in a pocket or purse. So unplug from your desktop now and then, and remember that what you’re building will maybe most likely be viewed on a phone, not a computer.

5. Stack the Odds in Your Favor With Proven SEO Methods

By now you’re probably realizing that SEO is at least as advanced as the technology behind self-driving cars. OK, we may be exaggerating a little, but not by much.

Google is that super loyal friend who always shows up, but who won’t hesitate to tell you when you’ve messed up. So it pays to take care of lots of details to keep building trust with the big G.

Earn Quality Backlinks

Google likes it when other websites talk about you. To Google, it’s a sign of trust, and you now know how hard that trust is to earn and keep. So don’t be shy about asking partners to mention you on their sites, or about writing articles for industry publications. Just steer clear of buying links or swapping them in bulk: Google treats link schemes as spam.

Show up, and show that you do. It’s that simple.

Understand Followed and Nofollow Links

There are two main kinds of links on a page: standard links, often called “dofollow,” which pass ranking signals to the page they point to, and links marked with the rel=”nofollow” attribute, which ask Google not to pass that credit along.

Both kinds still take visitors to the other page. The difference is how Google treats them.

When Google’s crawler scans your site, it gives weight to your standard links and follows them to assess the credibility of the sites you send visitors to. The same goes when another site points a standard link at yours, which is why a link from a trusted site carries real value.

The goal: drive traffic and build trust with Google.

A nofollow link, on the other hand, tells Google you don’t vouch for the destination. Since 2019, Google treats nofollow as a hint rather than a strict rule, and it added two more specific attributes: rel=”sponsored” for paid or affiliate links and rel=”ugc” for user-generated content such as comments. Complicated, but not that complicated.

Build Internal Links With Your Keywords

Internal linking means linking the pages of your site to one another, like this link to our SEO services page. Get it?

The idea is to build internal links without forgetting about keywords. In the link above, we used descriptive, SEO-related anchor text instead of a vague “learn more.”

Simple, but effective.

Take On Social Media

Social shares aren’t a direct Google ranking factor, but your overall presence on the web matters more and more. Active social accounts get your content seen, earn mentions and links, and drive people to search for your brand. So take care of your social media, stay active, get people talking about you, drive traffic, and add share buttons to your site.

Complete Your Google Business Profile

In a world where everyone navigates with their phone, there’s one tool you may be underestimating: your Google Business Profile (formerly Google My Business). It acts as your business’s digital ID card, and it’s also a way to boost your visibility on Google Maps and in local search results.

Quick and easy to set up, it’s a must for any business that serves customers in a specific area. Our Google local SEO guide shows you how to make the most of it.

Measure Your Results With Key Performance Indicators

We already covered this earlier, but we figured one more reminder wouldn’t hurt, given how central KPIs (key performance indicators) are to any digital marketing strategy.

Being able to measure your actions and their impact is now essential if you want results.

KPIs are the fuel that keeps your ship moving. Without them, you’re running in place. Simple as that.

So use tools to track your keyword rankings, your site traffic, your visitors’ behavior, and the reach of your campaigns. Honestly, we’re running out of ways to say how important KPIs are. Measure your performance. It’s a matter of life and death.
