~/pixels-not-characters

Search results cut by width, not by character count.

The 60- and 160-character rules are rough proxies. Results clip text at a fixed pixel width, so capitals and wide letters run out early while narrow letters fit far more. This measures your text with your browser’s own Arial metrics, at the sizes search results use.

~/who-reads-which-tag

Paste a head. See which tag each reader picks.

Search engines, social apps and browsers each look for a different tag first and fall back in their own order. This runs your text through the browser’s real HTML parser, so entities, attribute casing and duplicate tags behave exactly as on a live page.

~/what-these-tags-do

Four lines that decide your first impression.

Before anyone visits your page, they see a snippet of it in search results or a shared link. These tags control what that snippet says.

titleTitle tag<title>
The blue headline in search results and the text on the browser tab. It’s the single strongest on-page signal of what the page is about.tips_and_updatesPast about 60 characters Google cuts it off with “…”: lead with the words people search for.
notesMeta description<meta name="description">
The grey summary under the headline. It doesn’t affect ranking directly, but a good one gets more clicks.tips_and_updatesIf it’s missing or off-topic, Google writes its own from your page text.
shareOpen Graph<meta property="og:*">
Controls the preview card when your link is shared on Facebook, LinkedIn, Slack, WhatsApp and most chat apps.tips_and_updatesUse a 1200 × 630 image: smaller ones show as a tiny thumbnail or not at all.
travel_exploreRobots & canonical<meta name="robots"> · <link rel="canonical">
Robots says whether search engines may list the page; canonical says which URL is the “real” one when several show the same content.tips_and_updatesLeaving noindex on after launch is the most common reason a new page never appears in Google.
~/everywhere-it-shows-up

Same tags, six different cards.

Each app reads your tags its own way and cuts text at different lengths. These previews use what you typed above.

~/writing-them-well

Formulas that get clicked.

A good title says what the page is; a good description says why to click. These patterns work for most page types.

~/common-mistakes

Six mistakes that cost clicks.

closeSame title on every page
beforeHome | FileFormer
afterHEIC to JPG Converter | FileFormer
Duplicate titles make pages compete with each other and look identical in results.
closeBrand first
beforeFileFormer | Free Online Tools | HEIC to JPG
afterHEIC to JPG: Free | FileFormer
The first words carry the most weight and survive truncation. Lead with the topic.
closeKeyword stuffing
beforeheic jpg heic to jpg convert heic jpg free
afterConvert HEIC to JPG: free, in your browser
Repeated keywords read as spam to people and search engines alike.
closeDescription too long
beforeA 300-character paragraph…
afterUnder 160 characters, one clear promise.
Anything past ~160 characters is cut off: often right before the point.
closeMissing og:image
beforeno image → tiny grey link
afterog:image 1200 × 630
Shared links without an image get far fewer clicks in feeds and chats.
closenoindex left on
beforerobots: noindex, nofollow
afterrobots: index, follow
A leftover staging setting quietly hides the page from search entirely.
~/reference

Where each tag is defined, and who honours it.

Head tags come from four different authorities: the HTML standard, an IETF RFC, Facebook’s Open Graph protocol and individual search engines’ documentation. That is why the rules disagree.
