WordPress provides a reasonable SEO foundation out of the box — semantic HTML, clean URLs with the right permalink structure, a basic XML sitemap. For a competitive UK business site, that foundation is not enough. You need custom meta titles, meta descriptions, comprehensive sitemaps, schema markup, Open Graph / Twitter Card tags, content analysis. The two plugins that deliver all of this are Yoast SEO and Rank Math. This guide compares them, walks through installation and essential configuration, covers per-post SEO settings, and finishes with sitemap submission to Google Search Console.

Without an SEO plugin, WordPress cannot:
All of these are SEO essentials. A dedicated plugin fills every gap.
If you have not yet set up your permalink structure, do that first — SEO-friendly URLs are a prerequisite.

Free for core. Yoast Premium (~£99/year for one site) adds redirect manager, multiple focus keywords, internal linking suggestions, premium support.
Fast-growing challenger. Strong free tier — many features Yoast reserves for premium are included free in Rank Math. 2+ million active installations, recently overtook Yoast's growth rate.
Rank Math Pro (from ~£59/year) adds keyword rank tracking, advanced schema, Google Analytics integration, priority support.

For a budget-conscious UK small business, Rank Math's free tier gives more for no cost. For established sites with Yoast already configured and editors familiar with its content analysis, sticking with Yoast is sensible. For agencies managing many client sites, Rank Math's Google Search Console integration is a convenience.
Either plugin produces excellent SEO results when properly configured. Pick one; do not run both.
Critical rule: install only ONE SEO plugin. Running Yoast and Rank Math simultaneously causes duplicate meta tags, conflicting XML sitemaps and broken schema markup. This harms rankings.
Both plugins have a guided setup wizard covering the most important settings: site type, organisation details, social profiles, search appearance. Follow each step; you can change anything later.
After the setup wizard, review these settings to fine-tune.
Confirm the plugin is using your correct Site Title (from Settings > General) and an appropriate SEO-focused tagline. Avoid the default "Just another WordPress site".
Both plugins ask whether your site represents an organisation or an individual. UK businesses should select Organisation, provide legal entity name (as on Companies House), logo, contact details. Yoast and Rank Math use this for Organisation schema markup.
Templates use variables like %%title%%, %%sitename%%, %%excerpt%%. Defaults are usually reasonable; customise if you want a specific format. Common template:
Home: %%sitename%% | %%sitedesc%%
Post: %%title%% | %%sitename%%
Page: %%title%% | %%sitename%%
Configure which content types should be indexed:
Ensure enabled. URL is typically yourdomain.co.uk/sitemap_index.xml (Yoast) or yourdomain.co.uk/sitemap_index.xml (Rank Math). Visit the URL to confirm it renders without errors.
Enable Organisation schema with your business name, logo, contact details. Enable Article schema for blog posts. Enable Breadcrumb schema.
Upload a default Open Graph image (1200 × 630 px) for pages without featured images. Configure Twitter Card type (Summary with Large Image for most sites).
Each post and page gets an SEO meta box below the editor (Yoast or Rank Math, depending on which plugin is active).
The main term you want the page to rank for. The plugin analyses how well the content targets this keyword and provides suggestions.
The <title> tag shown in Google results and browser tabs. Max ~60 characters. Include the focus keyword early. Different from the page H1 (though often similar).
The blurb shown under the title in Google results. Max ~155 characters. Sells the click — treat it as an advertising copy exercise. Include the focus keyword once, naturally.
Short, keyword-rich. Already covered under permalinks.
Override the default Open Graph image and title for this specific page. Useful for blog posts where you want a custom share graphic.
Below the editor, Yoast shows readability and SEO scores with green/amber/red indicators; Rank Math gives a score out of 100 with itemised checks.
Do not worship the score. A green all-round does not guarantee ranking; a yellow score can rank brilliantly. Treat the analysis as useful hints, not gospel.
Pick schema type per post: Article, Blog Post, News, HowTo, FAQ. Most posts are Article or BlogPosting. FAQ schema for pages with Q&A content generates rich results sometimes.
Your SEO plugin generates the sitemap; Google Search Console needs to know about it.
search.google.com/search-console, sign in.https://yourdomain.co.uk).Once verified, in Search Console:
sitemap_index.xml (both Yoast and Rank Math use this).Google starts crawling the sitemap within hours. First full crawl can take days; subsequent updates are faster because Google knows where to look.
Search Console's Coverage report shows indexed vs excluded pages. Excluded pages are worth investigating — some exclusions are legitimate (noindex on tag archives), others indicate problems (accidental noindex on important pages).
An SEO plugin handles on-page SEO. Other factors remain your responsibility:
Server-level factors that directly support SEO:
Combined, the infrastructure lets your SEO work deliver its full value.
Which plugin should I choose, Yoast or Rank Math?
Either is excellent. Rank Math's free tier is more generous (includes redirect manager, Search Console integration, 404 monitor). Yoast is more established with a gentler learning curve. Try one; switch later if preferences change.
Can I switch from Yoast to Rank Math?
Yes. Rank Math includes an import tool for Yoast settings and metadata. Deactivate Yoast, activate Rank Math, run the import wizard. Takes 5–15 minutes.
Do I need to pay for the premium version?
For most UK small business sites, no. Free tier of either plugin covers the essentials. Premium features (redirect management, multiple focus keywords, keyword tracking) are genuine value-adds but not prerequisites.
What should I do if my focus keyword analysis shows red?
Review the specific suggestions. Common fixes: include the keyword in the H1 and first paragraph; include in meta description; add to one H2 or H3; ensure the slug contains it. But beware over-optimisation — readability matters more than hitting every green indicator.
How often should I update meta descriptions?
When a page's content, offer or target changes. Otherwise leave them stable. A well-written meta description is an evergreen asset.
Why is my page not ranking even after configuring SEO?
SEO is slow. Competitive niches take 6–18 months. Check that the page is indexed in Search Console, backlinks exist, content is genuinely useful, technical fundamentals are in place. SEO is a compound discipline, not a plugin-installation.
Do I need Schema for every page?
Article/BlogPost schema for blog posts; Organisation schema for the site as a whole; FAQ schema where relevant. Overdoing schema where it does not fit (fake FAQ just to get rich results) risks a manual penalty.
How do I handle canonical URLs?
Both plugins set canonicals automatically. For most pages, the canonical is the page's own URL. Override only when there is a specific reason (near-duplicate pages, product variants).
Should I noindex tag archives?
If you have few tags with substantial content per archive, index them. If you use tags loosely with one post per tag, noindex — thin content hurts.
Can I use an SEO plugin and Google Site Kit together?
Yes. Yoast or Rank Math handles on-page SEO; Site Kit brings Analytics and Search Console data into the dashboard. Complementary, not conflicting.
