How to improve SEO WordPress in 2026

Why SEO Matters?

The valid data I was able to find is that 8.5 to 13 billion times a day, people are using Google. It’s means that the agency’s clients still need to do Search Engine Optimisation to be found and picked among the competitors. Having social media = good. Having website = good. Being found without monthly ad spend = priceless.

This month, for example, I got a quote that it will take 15 000 USD to bring on this very website – 1 000 visitors from Google Ads. Pricy, isn’t it?

The same number of users could find the same website, using the same search queries in google for free, if the content is useful enough for users so Google could rank it higher.

Start with SEO Basics

How SEO-Friendly URLs looks like?

this is how default URL looks like

https://codelibry.com/?p=1278

This is how a user and SEO-friendly URL looks. Basically, you as a human, can easily read what the page is about without snippets or previews or opening the page

by default, wordpress generates URL like I’ve shown on example 1, but if you follow next steps – you’ll easily change them to desired structure, wordpress is quite flexible in this:

  1. Open admin panel
  2. Navigate to settings -> permalinks
  3. Choose the desired structre
  4. Hit save
  5. Flush cache if needed and enjoy.

How does proper site structure look for SEO?

There is no unique standard, but everything is controlled by common sense

For example,

https://codelibry.com/ - is Homepage

Then

https://codelibry.com/case-studies/ is page, where all case studies are stored - that's also called archive page in wordpress. Any general page that shows some type of content is called archive page: blog page, resources page, services, etc.

Then #2

https://codelibry.com/case-studies/how-uk-marketing-agency-combines-outsourcing-with
-in-house-development/ is called single case study page

So the rule of thumb is to slice content into blocks that make sense and have a certain hierarchy. For B2B websites, where my agency has the most experience with – it’s always something like this:

  • Homepage
  • Services ( general or archive page)
  • Service detailed page ( single page)
  • Blog/resources + single page
  • Contact
  • Testimonials
  • About
  • Pricing
  • FAQ
  • etc.

Each page is an entry point for SEO for 2 types of queries:

  • Commercial – likely service page, page where you’re expecting filling the form or generate leads.
  • Informational – likely blog or other resource page, where you provide information and make visitor kinda like subscriber that potentially could convert into lead or client

How to optimize Content for seo?

This is a question that is more likely to be better addressed to the team of SEO manager + copywriter. In 2026 AI could help with some copywriting, when the SEO manager advises on the heading structure, page structure and will do keyword research

How to find keywords for SEO?

Tricky question – basically, you decide what your keywords are. More likely, these are words and queries that your client’s clients are using to find the relevant information.

For our website it could be

"Wordpress development", "WooCommerce development", "Wordpress outsourcing" etc.

2 types of tools are best for this:

  • Google Keyword Planner – shows how many searches were done by certain query last month and dynamics how amount of search queries varies.
  • ANY SEO tool based on your website could help find competitors and their most popular keywords, so you could filter them. Most popular tools are Semrush, Ahrefs, SE ranking, etc.

In 99 of 100 situations – SEO manager will do this and even junior level should be enough for good results. With AI – I see a lot of restrictions like they don’t always see real-life situations and often “made up” the list. I mean they can’t access websites and search through google the same way as SEO tool will do

Headings and Meta Tags

Same story – you either ask AI or the SEO manager. For this article, the SEO manager did a draft of Heading structure for me, volume of searches per month, defined heading1 – so I just laid out my thoughts and hit publish

With Meta Tags – it’s a similar story. So it’s the page title and description. Most WordPress SEO plugins like Yoast SEO, RankMath or All in One SEO pack have the template ( defined by you or your developer or SEO manager or Marketer) like

Title = {Heading 1} | {Site name}
Description = Check out how {h1} could help {type of business} or whatever fits your business, really.

With this application, any published article, post, or page will have at least something under title and description and will perform better than nothing. When polished by SEO manager, = skyrocket results.

How improving Website Speed affects SEO?

Experts in my LinkedIn feed state that performance is important, but not the only important factor. So you should be doing link building, have a proper structure, etc. and have high loading speed will only boost the performance

Imagine 2 websites. Your client’s website and its competitor. Most impact will have content relevance, links, etc – but if all of these are very similar, then a faster website will be ranked higher.

Now, most things agency owners don’t understand is how to measure website speed. If you think Google Page Speed Insights, you’re wrong. The most important for Google is real users results, so if your website has more than 1000 visitors per month ( approximately ) – you could expect to see Core Web Vitals asessment in your Google Search Console.

Usually for desktop first and then for mobiles, but depends on origin of each website traffic. This website has majoirity of desktop traffic, while others could have more mobile traffic, especially in B2C segment

Core Web Vitals has 3 results

  • No data – you need more traffic
  • Passed – for 75+% of website visitors it loads fast
  • Failed – for <75% of website visitors it loads fast – you need a developer to help with website speed optimisation

Make Your Site Mobile-Friendly

It may sound obvious, but a lot of websites have responsive issues. When I do cold outreach for my agency – all the time I see responsive issues on other agencies websites, when they are selling responsive websites to the clients

Google can track this as well. Best case is to have manual check by QA once a month as part of a maintenance plan – in that case, if an issue is found, it sometimes could be sold as an upsell to the client or fixed under warranty. Anyway – both outcomes are good.

Why you need to use an SEO Plugin?

We don’t have all the time in the world, that’s why we’re using AI, automations and plugins to do the routine job:

  • Handle social previers
  • Handle automatic meta-tag creation
  • Add Schema markup etc.
  • Control canonicals
  • Add robots.txt and llms.txt

We could do all of this ourselves, but we waste dozens of hours per website every single month.

On this website I’m using Yoast SEO

Some teams like RankMath or All-in-One SEO pack. Just do what your team does on every project to keep things consistent across every wordpress client or do what your vendor prefers if you outsource the job, as they will be responsible for results and better to work in comfy environment

Optimize Images

God, not enough agency owners realise how bad most teams work with image optimisation. Here is what should be done:

  • Proper size
  • Proper format
  • Proper title
  • Proper Alt
  • Proper type

I was covering this in my large guide – for SEO this makes sense in terms of speed + meta information, so users and crawlers and even AI understood what is that for.

Why and how to build Internal Links?

Crawlers like an AI bot or a Google bot could find any link by visiting the sitemap.xml – file with all links from your client’s website. Users, on the other hand, need a link to the page placed somewhere so they could use it

When using SEO tools, it’s common to notice a type of warning for pages that have 1 internal link. That’s why in the previous section I’ve linked other 2 articles. To help you and the Google bot to find another material and understand that they are connected.

How to track SEO performace?

Most common answer is Google Search Console + Analytics tools like SE Ranking, Semrush, Ahrefs and Google Analytics.

GSC is free.

Google Analytics is free.

The rest are billed on monthly or yearly basis and agencies usually need it when selling SEO services to clients. If you don’t – you may consider to use it just for your website, but sure thing SEO agency partner will share all reports with you

Common SEO Mistakes

For any business:

Delaying the start.

Businesses who started SEO 20 years ago now rock because their websites more likely gained leads and have a budget for competition. For those who is starting now – well, it’s time to invest money and time and effort.

For agencies:

Have sloppy development team – that’s where Codelibry could help. From Any tech issues to speed optimisation.

Final Tips

SEO is a long-term game for agencies and their clients. Links have the biggest impact – then tech part, like optimisation.

And the content is King so make your content interesting and work with clients to make their content interesting to force readers spending a lot of time on the pages and send signals to google that each page is very interesting and worth ranking higher
