SmartCrawl SEO for WordPress — the Basics, and How the Plugin Helps

Search engines don't rank plugins. They rank pages — pages that say clearly what they're about, load quickly, and are easy to crawl. An SEO plugin such as SmartCrawl (from WPMU DEV), Yoast SEO or Rank Math makes the on-page part of that easier to manage. But the fundamentals are the same whichever tool you use, and most of them are worth understanding before you install anything.

Here's what actually matters in 2026, and where a plugin fits.

The fundamentals a plugin helps you manage

Titles and meta descriptions. Every page needs a unique title (roughly 50–60 characters) and a description that reads like a sentence a person would click. This is where a plugin earns its keep: set a template once — "Page Title – Business Name" — and it applies everywhere, with per-page overrides when you want to hand-write something.

One H1 per page. The H1 is the page's headline; subheadings should be H2/H3 underneath it. Most themes handle this correctly, but page builders make it easy to accidentally stack two H1s. Check your key pages once.

Clean permalinks. /services/kitchen-remodeling/ beats /?p=123. This is a WordPress core setting (Settings → Permalinks), not a plugin feature. Set it early — changing it later means redirects.

XML sitemap. WordPress core has shipped its own sitemap at /wp-sitemap.xml since version 5.5. SEO plugins replace it with a richer one (images, last-modified dates, exclusions) and let you control what's in it. Either way, submit the sitemap URL in Google Search Console.

Structured data (schema). JSON-LD markup tells search engines what kind of thing a page is — a local business, an article, a product, a recipe — which is what unlocks rich results. Plugins generate the common types automatically; you fill in your organisation details once.

Image alt text. Alt text describes an image for people using screen readers and for search engines that can't see it. No plugin writes it for you well; the plugin's on-page check will nag you when it's missing, which is the useful part.

Internal linking. Link from your strong pages to the ones you want to rank, using descriptive anchor text ("our roof repair services", not "click here"). Plugins can suggest links; you decide which make sense.

The fundamentals a plugin can't do for you

Search Console verification. Verify your site in Google Search Console and Bing Webmaster Tools. That's where you see real queries, indexing problems and manual actions. Some plugins let you paste the verification tag; the account and the reading are on you.

Core Web Vitals. Google measures loading speed, responsiveness and visual stability on real visits, and uses them as a ranking input. These come from your hosting, caching, theme and image sizes — not from an SEO plugin. See our intro to Core Web Vitals.

Mobile-first indexing. Google indexes the mobile version of your page. If a section is hidden on phones, it effectively doesn't exist for ranking. Check your important pages on an actual phone.

HTTPS everywhere, no mixed content, sensible redirects. Infrastructure jobs, not plugin settings.

Run exactly one SEO plugin

This is the most common self-inflicted SEO problem we see. Two SEO plugins active at once — say, SmartCrawl plus Yoast, or a plugin plus a theme that also emits SEO tags — will output two title tags, two meta descriptions and two JSON-LD blocks on every page. Search engines don't reward you twice; they get conflicting signals and pick one, or ignore both.

The same double-emit happens when a page builder, a schema add-on, or a "social share" plugin also writes OpenGraph or structured data. View the source of your homepage and search for og:title and application/ld+json. If either appears more than once, something needs turning off.

Pick one plugin, configure it, and disable the overlapping features in everything else.

Which plugin?

They cover the same ground. SmartCrawl is a natural fit if you're already in the WPMU DEV ecosystem; Yoast is the most widely documented; Rank Math bundles more into its free tier. The right one is the one you'll actually keep configured — and switching later is possible but rarely worth the disruption.

Setting it up well (any of them)

1. Set title and description templates before you have hundreds of pages.
2. Fill in organisation details and a default share image so nothing ships blank.
3. Confirm the sitemap is on and submitted in Search Console.
4. Run the on-page check on your homepage and top service or product pages, and clear the real warnings.
5. Ignore the score. A helpful page written for people beats a thin one that scores 100.

An SEO plugin handles the tags and markup on each page. Everything underneath — speed, HTTPS, clean HTML, a server that stays up — is the foundation it sits on, and no plugin can fix a slow one.
