Website SEO

Checks whether individual pages give Google enough information to understand their topic and display them properly in search.

Social share preview

Open Graph

Open Graph tags control the title, description, and image shown when your page is shared.

Why you care: A poor preview can make people less likely to click a shared link.

What to do: Add Open Graph tags with a title, description, and image for key pages.

Impact: LowDifficulty: Easy
Technical details

og:title, og:description, and og:image meta tags define social card previews used by most platforms.

Low-content page

Thin content

Thin content pages have little useful text for visitors or search engines to work with.

Why you care: With little to read, search engines struggle to understand what the page is about and visitors may not find it useful.

What to do: Add helpful, original content that answers what a visitor would want to know.

Impact: MediumDifficulty: Moderate
Technical details

Low word count alone is not a penalty, but pages with little unique value are harder to rank.

Image description

Alt text

Alt text is a written description of an image, used by screen readers and shown when an image cannot load.

Why you care: It helps visitors who cannot see the image and gives search engines context about the page.

What to do: Add short, accurate descriptions to your images.

Impact: LowDifficulty: Easy
Technical details

The alt attribute provides accessible names for images and contextual signals for image search.

Search-result description

Meta description

A meta description is the short line of text that can appear under your page in Google. It helps people decide whether to click.

Why you care: Without it, Google writes its own snippet, which may not say what you want and can reduce clicks from search.

What to do: Write a one or two sentence description of the page, around 150 characters, and add it to the page.

Impact: MediumDifficulty: Easy
Technical details

The <meta name="description"> element provides a summary search engines may use as the search-result snippet. It is not a ranking signal but influences click-through.

Main page heading

H1

An H1 is the main heading at the top of the page. It tells visitors and search engines what the page is about.

Why you care: Without one, it is harder for both people and search engines to quickly understand the page.

What to do: Add one clear main heading that describes the page.

Impact: MediumDifficulty: Easy
Technical details

A single <h1> provides the primary topical heading. Multiple H1s or none weakens semantic structure.

Repeated page titles

Duplicate title

When several pages share the same title, search engines can struggle to tell them apart.

Why you care: This can make it harder for the right page to appear for a given search.

What to do: Give each page its own unique, descriptive title.

Impact: MediumDifficulty: Easy
Technical details

Duplicate <title> elements dilute topical relevance and can trigger keyword cannibalisation across URLs.

Page title label

Title tag

A title tag is the clickable headline for your page in Google results and a key signal for what the page is about.

Why you care: Without a clear title, Google has to guess what the page is about, which can make it harder for the right searches to find you.

What to do: Add a unique, descriptive title of about 50–60 characters to each affected page.

Impact: HighDifficulty: Easy
Technical details

The <title> element is a primary on-page ranking signal and the main headline in SERPs. Each page should have one unique, descriptive title.

Technical Health

Checks whether search engines can properly access, interpret, and navigate your website.

Secure connection

HTTPS / SSL

HTTPS encrypts the connection between your visitors and your website.

Why you care: Browsers warn visitors about non-secure sites, which can erode trust, and Google prefers secure sites.

What to do: Install an SSL certificate and switch your site to HTTPS.

Impact: HighDifficulty: Moderate
Technical details

TLS encrypts traffic and is a lightweight ranking signal. Browsers flag HTTP as insecure, hurting trust and conversions.

Access trouble

Crawl error

A crawl error means a search engine tried to visit a page and could not reach it properly.

Why you care: If a page cannot be crawled, it cannot appear in search results.

What to do: Check whether the page loads normally and is not blocking search engines.

Impact: MediumDifficulty: Moderate
Technical details

Crawl errors include DNS/connect failures, 5xx, and robots-disallowed URLs. They block indexation of the affected path.

Hide from search

Noindex

A noindex instruction tells search engines not to include a page in search results.

Why you care: If this is set by mistake, a page you want found will not appear in Google.

What to do: Check whether the page should be indexed and remove the noindex instruction if so.

Impact: HighDifficulty: Easy
Technical details

A robots meta noindex or X-Robots-Tag removes the URL from the index. Often set accidentally during staging.

Page map for search engines

XML sitemap

An XML sitemap is a list of your pages you give to search engines to help them find everything.

Why you care: Without it, search engines may take longer to discover some of your pages.

What to do: Generate an XML sitemap and submit it through Google Search Console.

Impact: MediumDifficulty: Easy
Technical details

An XML sitemap lists canonical URLs with optional lastmod/priority metadata, accelerating discovery and re-crawl signalling.

Crawler instructions

robots.txt

robots.txt is a small file that tells search engines which areas they may crawl.

Why you care: A missing or misconfigured file can leave search engines unsure what to access — or accidentally block important pages.

What to do: Confirm a robots.txt file exists and is not blocking important pages.

Impact: LowDifficulty: Easy
Technical details

robots.txt provides crawler directives (Allow/Disallow, Sitemap). Misconfiguration can deindex or over-expose paths.

Preferred page version

Canonical URL

A canonical tag tells Google which version of similar pages you want treated as the main one.

Why you care: If several URLs contain similar content, this can prevent Google from getting confused about which one should appear in search.

What to do: Confirm each page points to its preferred version with a canonical tag.

Impact: MediumDifficulty: Moderate
Technical details

The rel="canonical" link element consolidates ranking signals across duplicate or near-duplicate URLs to a preferred URL.

Unlinked page

Orphan page

An orphan page is a page no other page on your site links to, so it is hard to find.

Why you care: If nothing links to it, visitors and search engines are unlikely to reach it.

What to do: Add a link to the page from a relevant place on your site.

Impact: LowDifficulty: Moderate
Technical details

Orphan pages lack internal link equity and crawl paths, reducing indexation likelihood.

Performance

Measures whether your website loads and responds quickly enough to provide a good visitor experience.

Loading experience

Core Web Vitals

Core Web Vitals are Google measurements of loading speed, responsiveness, and visual stability.

Why you care: Slow or jumpy pages frustrate visitors and are a small part of how Google ranks pages.

What to do: Improve loading speed and responsiveness with whoever manages your site.

Impact: HighDifficulty: Advanced
Technical details

Core Web Vitals (LCP, INP, CLS) are field-measured UX signals used in Google ranking.

Local Visibility

Checks information that can help nearby customers discover your business in local search and Google Maps.

How to reach you

Contact information

Contact information means the phone number, email, or address people use to reach your business.

Why you care: If it is hard to find, potential customers may give up and go elsewhere.

What to do: Make your contact details easy to find on every page.

Impact: MediumDifficulty: Easy
Technical details

Visible NAP and contact links improve user experience and reinforce local entity consistency.

Local business info

Local business schema

Local business schema is code that tells search engines your name, address, hours, and area.

Why you care: It helps you show up in local results and on Google Maps.

What to do: Add local business structured data with accurate name, address, and hours.

Impact: HighDifficulty: Moderate
Technical details

LocalBusiness JSON-LD provides NAP, opening hours, and geo data, supporting local pack and Maps eligibility.

AI Search Readiness

Checks whether the basic systems Google and AI tools use to discover and understand your website are properly configured.

Structured business information

Schema markup

Schema markup is extra code that tells search engines specifics about your business — like hours, address, and reviews.

Why you care: Without it, search engines and AI tools have to guess, which can make you less visible in rich results and AI answers.

What to do: Ask whoever manages your site to add structured data describing your business.

Impact: MediumDifficulty: Moderate
Technical details

JSON-LD structured data (LocalBusiness, Organization, FAQPage) gives search engines and LLMs explicit entity attributes.
