Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

SEO Checker

Find out if you're flouting any SEO rules.

Initialisation and Usage

Pass in the path to your HTML file to initialise the checker.

Remember to .report() after all your checks!

const Checker = require('Checker')
var checker = new Checker('./path/to/file.html')

checker.inspectTitle()
        .inspectH1()
        ._hasMissingAttribute('meta', 'content')
        .report()
//  head title
//    -> <title> not found
//  h1
//    -> There should not be more than 1 <h1> tag(s). Count: 2
//  meta
//    -> <meta> without content attribute or has empty content attribute: 1

API

The following methods adhere to certain pre-defined SEO rules:

.inspectTitle()

Logs an error if there is no <title> tag in the <head>.

.inspectMeta([[names]])

Logs an error if the requisite names for <meta> tags are not found.

// name defaults: ['keywords', 'description']
// takes in array of additional names

...
checker.inspectMeta(['foo'])
// meta
//   -> <meta name="keywords"... > not found in <head>
//   -> <meta name="foo"... > not found in <head>
.inspectH1()

Logs an error if there is more than one <h1> tag in the document.

.inspectImages()

Logs an error if <img> tags do not have alt attributes declared or if alt attributes are left empty.

.inspectAnchors()

Logs an error if <a> tags do not have rel attributes declared or if rel attributes are left empty.

.inspectStrong(maxCount = 15)

Logs an error if there are more than 15 (default) <strong tags.

...
checker.inspectStrong(5)
// strong
//   -> There should not be more than 5 <strong> tag(s). Count: 11
.report()

Print out logged errors in the terminal. Or view the error object with checker.errors.

img
  -> <img> without alt attribute or has empty alt attribute: 3
a
  -> <a> without rel attribute or has empty rel attribute: 2
h1
  -> There should not be more than 1 <h1> tag(s). Count: 2
strong
  -> There should not be more than 5 <strong> tag(s). Count: 11
head title
  -> <title> not found
meta
  -> <meta name="keywords"... > not found in <head>
The next few methods allow you greater flexibility in defining your own rules.
._exists(selector)

Logs an error if selector is not found.

...
checker._exists('div')
// { 'div': '<div> not found' }
._exceeds(selector, n)

Logs an error if n is exceeded.

...
checker._exceeds('.foo', 2)
// { '.foo': 'There should not be more than 2 <.foo> tag(s). Count: 4' }
._hasMissingAttribute(selector, attribute)

Logs an error if selector does not have a specific attribute declared or has empty attribute

...
checker._hasMissingAttribute('div', 'class')
// { div: '<div> without class attribute or has empty class attribute: 1' }
