This is a module that shall bring thou great honor, Mr. Knoll!!!

How does it work? Does it create fields for those tags? I guess, you still have to insert the markup into the template files yourself? Or is it "more userfrendly" already and does everything for you?

Nico: thanks, this looks interesting! Testing it right now, so might have more comments later, but first things first: you might want to add some isset-checks to module config. Seeing quite a few notices and warnings before saving module config.

Sorry, forget that, it's not about config. The problem is occurring in init(), when trying to check for $this->page->template. While viewing the module settings, $this->page doesn't seem to be available yet, which is causing some issues :)

Edit: here's a diff for changes I had to make locally to get this module running. Wouldn't work at all before that, possibly because I've got debug mode on. Not sure if they're all required, implemented the way you'd want them, etc. and some of them might be specific to my environment.

Also, moving the hooks from init() to ready() should ensure that API is ready by that time, but it could cause other (potentially unwanted) side-effects..

This looks excellent! I've been manually creating my SEO tabs. So this is a huge relief! And I really dig the preview. (Better than what it looks like with WordPress SEO, for sure.)

Kudos!  ^-^  :D

I know :) But at least the open graph stuff is really useful and custom title and description isn't bad, too :)

(And I think it's better than a lot of WordPress SEO modules, so maybe another pro for choosing pw)

Thanks for the module Nico! Could you update the GitHub readme to either have instructions like this or link to this page? I mention it just for those folks that might download the module but not know about this thread.

Just working on some more options (like using parent values, smart values, excluding templates, special permissions, ...). After that I will update all of the descriptions :)

Just digging through some of my own bits and I noticed that somewhere someone said that for facebook and twitter, it helps if the image is square. Is it worth adding a size() to this?

Well I think facebook changed it. They are supporting all formats now I think. 

But if you want to you can add an image field with cropped images and add it to image automatically via "smart image" field

Hi Nico

Thanks for the module. As we need here multilingual SEO as for good practice we can't mix i.e. Thai, Chinese, Russian, English letters - The much better way is therfore to have all those textfields made by textlanguage fields and not only text fields. Would this be feasible or would we need to create a multilingual version of the module?

Beside the stuff you mentioned already above here are some more fields you should add:

MSN Verification
Yahoo Verification
Web of Trust (wot) Verification
Google Crawler Verification

Like Google Analytics add Piwik Analytics too.

For the Title it would be great to have a prefix and a suffix for the Title which could be recurring if empty. This way you can create great Broser titles from each page without loosing a constant part of the title - either in front or in the back.

Title prefix

Title suffix

PageTitle Constant Description Default Apply tmpl-sitetitle to absolute <title>

There is a prefix/suffix for your pagetitle defined in your root template settings.

If you use the SEO-Absolute-Pagetitle settings you can disable this suffix/prefix here.

There is a prefix/suffix for your pagetitle defined in your root template settings.

If you use the SEO-Pagetitle-Suffix/Prefix settings you can disable this suffix/prefix here.

Position of Sitetitle (from template) Possible options:

Sitetitle-Pagetitle (eg. Example Company: About us) Pagetitle-Sitle (eg. About us: Example Company)

Sitetitle-Pagetitle (0) Sitetitle Overwrite the template sitetitle with a custom one  

Sitemap Constant Description Default Enable Enables output (if set on root-pid of tree) and indexing for the whole subtree enabled Page limit Limit pages on sitemap-xml-pages 10000 Limit to current language

Limit output of the sitemap to the current language. This will enable multi-language-domain sitemaps. eg:

  • www.example.com (FE-Language is english) will output only english pages
  • www.example.de (FE-Language is german) will output only german pages

This option was ported from the extension configuration and will replace this configuration.

disabled Default change frequency Default change frequency for sitemap cache (will be cached!)   Page priority

Default page priority if the page have no own priority set

Page priority will be calculated by:

( [page priority] – [priority modificator] ) * ( 1/[page depth] * [page multiplier] )

1 Page priority depth multiplier Page depth multiplier, see formula in page priority 1 Page priority depth modificator Page depth modificator, see formula in page priority 1

-----

If now this gets combined with a cron job (scheduler task) than you are all set for your SEO needs.
 

Scheduler Tasks Scheduler Task Description Frequency MetaSEO Cleanup This task cleans up old database entries in the tx_metaseo_sitemap table. One run per day MetaSEO sitemap.txt builder

This task builds a real sitemap.txt file in the upload directory.

  • Directory: uploads/tx_metaseo/sitemap_txt/
  • Sitemap: sitemap-r{ROOTPID}.txt.gz

If language domain support is active:

  • Sitemap: sitemap-r{ROOTPID}-l{LANG}.txt.gz

{ROOTPID} is the Page-UID from the root pages in your TYPO3 installations.

{LANG} is the language id (only active if language domains are active).

Hint: These files are already gziped.

One run per day MetaSEO sitemap.xml builder

This task builds a real sitemap.xml files in the upload directory.

  • Directory: uploads/tx_metaseo/sitemap_xml/
  • Sitemap-Index: index-r{ROOTPID}.xml.gz
  • Sitemap-Page: sitemap-r{ROOTPID}-p{PAGE}.xml.gz

If language domain support is active:

  • Sitemap-Index: index-r{ROOTPID}-l{LANG}.xml.gz
  • Sitemap-Page: sitemap-r{ROOTPID}-l{LANG}-p{PAGE}.xml.gz

{ROOTPID} is the Page-UID from the root pages in your TYPO3 installations.

{PAGE} is the current page of the sitemap.

{LANG} is the language id (only active if language domains are active).

The index will refer to all page sitemaps so you only have to reference to the sitemap index.

Hint: These files are already gziped.

But most important is that it contains the ability to do multilingual SEO - which means depending on your language you can display the same or different or additional values in your text fields.

Thanks

:-) Hi Martin

well if you wanna play in the top CMS leauge than better adjust to the encyclopedia ;-) - and get one new Processwire customer after the other converting TYPO3 Enterprise Level Sites to Processwire. The market shares of TYPO3 in Europe - especially Germany, Netherlands, Austria, Switzerland are great and very highprized. But with only WordPress Like seo features you won't get them at all.

No joke - If you understand SEO the right way and we are doing it here since years,aha than you really should use all that stuff the right way. To beat wordPress might be enough what is in there right now but this is just the beginning of what could be achieve with an enterprise SEO feature.

Perhaps you meant the way the data got clutterd in the post - so perhaps have a look to the link I have posted - It shows very clear what values are necessary. We use that tool (actually the predecessor of it called tq_seo) since many years with great success.

now we try to convince more and more customers to use Processwire instead of TYPO3 and WordPress (which is already crab by the way as they should have kept it as a blogging plattform for what it had been developed originally.

@andi: thanks for the response! I took a look on the typo3 site and it looks like a good place for inspiration. I'll probably adapt some of the options there. But first I'm going to clean the current version and try to get multi language integrated (already tried it but it didn't work. So I have to try again :) )

yep referring to that. :-) But thanks for the great list I did have an overview of the page you linked to.

Lisandi, when you want a module that controls it all you're left with a tool build on assumptions. Nico has build a great tool especially for the smaller websites. We're in a business sending 100.000+ newsletters a week. We have 4 big news portals and multitude of articles are published everyday, you have to automate SEO (read custom build functions). No ready to use tool could be used here, many things can't be controlled in a reasonable way with inputfields and you can't have one tool to do the job.

Was going to mention this earlier but it slipped my mind, so: Nico, what's your take on the storage method this module uses (saving all content to module config, i.e. the data column of related Modules table entry) and the obvious limitations it causes?

Based on some quick testing, using suggested description length, this module should be able to store data for roughly 300 pages -- though actual number depends a lot on the stored data itself. I was just wondering if it would make sense to reconsider the storage method, offer an alternative method for large sites, mention this somewhere.. and/or perhaps make the module aware of how much "quota" it still has?

I'm asking 'cause this seemed like an interesting choice for some of our sites, but it's not that rare for those to have hundreds or even thousands of pages.. so if the client ever gets too enthusiastic, there's going to be a problem ;)

Also: you might want to add garbage collection for removed pages. That's going to limit the scope of aforementioned scalability issue a bit.

      Wire Mail SMTP

      An extension to the new WireMail base class that uses SMTP-transport

      This module integrates EmailMessage, SMTP and SASL php-libraries from Manuel Lemos into ProcessWire. I use this continously evolved libraries for about 10 years now and there was never a reason or occasion not to do so. I use it nearly every day in my office for automated composing and sending personalized messages with attachments, requests for Disposition Notifications, etc. Also I have used it for sending personalized Bulkmails many times.

      The WireMailSmtp module extends the new email-related WireMail base class introduced in ProcessWire 2.4.1 (while this writing, the dev-branch only).
       
      Here are Ryans announcement.



      Current Version 0.2.6
      get it from the Modules Directory Install and Configure

      Download the module into your site/modules/ directory and install it.

      In the config page you fill in settings for the SMTP server and optionaly the (default) sender, like email address, name and signature.
      You can test the smtp settings directly there. If it says "SUCCESS! SMTP settings appear to work correctly." you are ready to start using it in templates, modules or bootstrap scripts.


      Usage Examples
      The simplest way to use it:
      $numSent = wireMail($to, $from, $subject, $textBody); $numSent = wireMail($to, '', $subject, $textBody); // or with a default sender emailaddress on config page This will send a plain text message to each recipient.
       
      You may also use the object oriented style:
      $mail = wireMail(); // calling an empty wireMail() returns a wireMail object $mail->to($toEmail, $toName); $mail->from = $yourEmailaddress; // if you don't have set a default sender in config // or if you want to override that $mail->subject($subject); $mail->body($textBody); $numSent = $mail->send(); Or chained, like everywhere in ProcessWire:
      $mail = wireMail(); $numSent = $mail->to($toEmail)->subject($subject)->body($textBody)->send(); Additionaly to the basics there are more options available with WireMailSmtp. The main difference compared to the WireMail BaseClass is the sendSingle option. With it you can set only one To-Recipient but additional CC-Recipients.
      $mail = wireMail(); $mail->sendSingle(true)->to($toEmail, $toName)->cc(array('person1@example.com', 'person2@example.com', 'person3@example.com')); $numSent = $mail->subject($subject)->body($textBody)->send(); The same as function call with options array:
      $options = array( 'sendSingle' => true, 'cc' => array('person1@example.com', 'person2@example.com', 'person3@example.com') ); $numSent = wireMail($to, '', $subject, $textBody, $options); There are methods to your disposal to check if you have the right WireMail-Class and if the SMTP-settings are working:
      $mail = wireMail(); if($mail->className != 'WireMailSmtp') { // Uups, wrong WireMail-Class: do something to inform the user and quit echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; return; } if(!$mail->testConnection()) { // Connection not working: echo "<p>Couldn't connect to the SMTP server. Please check the {$mail->className} modules config settings!</p>"; return; } Following are a ...


      List of all options and features


      testConnection () - returns true on success, false on failures


      sendSingle ( true | false ) - default is false

      sendBulk ( true | false ) - default is false, Set this to true if you have lots of recipients (50+)


      to ($recipients) - one emailaddress or array with multiple emailaddresses

      cc ($recipients) - only available with mode sendSingle, one emailaddress or array with multiple emailaddresses

      bcc ($recipients) - one emailaddress or array with multiple emailaddresses

       
      from = 'person@example.com' - emailaddress, can be set in module config (called Sender Emailaddress) but it can be overwritten here

      fromName = 'Name Surname' - optional, can be set in module config (called Sender Name) but it can be overwritten here


      priority (3) - 1 = Highest | 2 = High | 3 = Normal | 4 = Low | 5 = Lowest

      dispositionNotification () or notification () - request a Disposition Notification


      subject ($subject) - subject of the message

      body ($textBody) - use this one alone to create and send plainText emailmessages

      bodyHTML ($htmlBody) - use this to create a Multipart Alternative Emailmessage (containing a HTML-Part and a Plaintext-Part as fallback)

      addSignature ( true | false ) - the default-behave is selectable in config screen, this can be overridden here
      (only available if a signature is defined in the config screen)

      attachment ($filename, $alternativeBasename = "") - add attachment file, optionally alternative basename


      send () - send the message(s) and return number of successful sent messages


      getResult () - returns a dump (array) with all recipients (to, cc, bcc) and settings you have selected with the message, the message subject and body, and lists of successfull addresses and failed addresses,


      logActivity ($logmessage) - you may log success if you want

      logError ($logmessage) - you may log warnings, too. - Errors are logged automaticaly
       
       
      useSentLog (true | false) - intended for usage with e.g. third party newsletter modules - tells the send() method to make usage of the sentLog-methods - the following three sentLog methods are hookable, e.g. if you don't want log into files you may provide your own storage, or add additional functionality here

      sentLogReset ()  - starts a new LogSession - Best usage would be interactively once when setting up a new Newsletter

      sentLogGet ()  - is called automaticly within the send() method - returns an array containing all previously used emailaddresses

      sentLogAdd ($emailaddress)  - is called automaticly within the send() method

      Call ProcessWire API Functions Inside STRING
      Github Repo
      Current status : BETA
      Each called method must return string value !
      I added all functions, but not tested all. I focused page(), page()->render and field properties (label, description and notes). I also tested some basic pages() api calls.
      Your API calls must start with { and must end with }. For use multiple arguments inside functions, separate arguments with ~ char.
      NOTE If you pass directly arguments to api {page(title)}, this call will check for requestedApiCall()->get(arguments).

      This module corrects a few things that I find awkward about the "Add New Template" workflow in the PW admin. I opened a wishlist topic a while back because it would good to resolve some of these things in the core, but this module is a stopgap for now.
      Originally I was going to share these as a few standalone hooks, but decided to bundle them together in a configurable module instead. This module should be considered alpha until it has gone through some more testing.
      Add Template Enhancements
      Adds some efficiency enhancements when adding or cloning templates via admin.

      Features
      Derive template label from name: if you like to give each of your templates a label then this feature can save some time. When one or more new templates are added in admin a label is derived automatically from the name. There are options for underscore/hyphen replacement and capitalisation of the label. Edit template after add: when adding only a single template, the template is automatically opened for editing after it is added. Copy field contexts when cloning: this copies the field contexts (a.k.a. overrides such as column width, label and description) from the source template to the new template when using the "Duplicate/clone this template?" feature on the Advanced tab. Copy field contexts when duplicating fields: this copies the field contexts if you select the "Duplicate fields used by another template" option when adding a new template. Usage
      Install the Add Template Enhancements module.
      Configure the module settings according to what suits you.

      Hi,
      I've put in a support request (as a followup on an existing one) for this but it's nearly 10pm Ryan's time, so I thought I'd ask on here just in case someone can help...
      Yesterday we purchased ProDrafts, but I couldn't get the key to validate. Every time I hit submit on the module settings screen the key would be removed from the field I entered it in, and then it would complain about the missing value. I put in a support request and Ryan responded last night. It turned out it was because we're behind a proxy/firewall. He gave me a fix to get around that issue - some code to go into admin.php. I put that code in and saved admin.php, but now I can't even get into our admin anymore!
      (Just to clarify, I took the code back out and saved admin.php but that made no difference. It's definitely not the new code causing the error.)
      The errors relate to a lack of permission on the ProDrafts module (see attached screenshot). We do have a key, but evidently the code Ryan gave me to add the key in via admin.php isn't taking effect before the error is thrown...?
      I tried removing the ProDrafts directory from the modules directory, but that hasn't helped.
      Is there a hook I can put in somewhere to tell it not to load ProDrafts at all, or not check the permissions? Or is there some way to manually uninstall it from the file system?
      Thanks!

      I just made a textformatter module that allows you to insert dummy content (lorem ipsum style) in text fields via shortcodes.
      Usage is simple - just type for example [dc3] into a textarea with this textformatter applied (plain textarea or CKEditor) and it will be replaced at runtime by 3 paragraphs of dummy content. It can also be used to populate text fields (for headings etc) using e.g. [dc4w]. This will produce 4 words (rather than paragraphs) at runtime.
      The actual content comes from an included 'dummytext.txt' file containing 50 paragraphs of 'Lorem ipsum' from lipsum.com. The 50 paragraphs is arbitrary - it could be 10 or 100 or anything in between, and the contents of that file can be changed for your own filler text if you wish.
      The slightly clever bit is that for any given page, the same content will be returned for the same tag, but the more paragraphs available in 'dummytext.txt', the less likely it is that two pages will get the same content (very roughly speaking - it's actually based on the page ID) so content selection is determinate rather than random, even though only the tags are saved to the db.
      Update
      Tags now work like this -
      [dc3] - Show 3 paragraphs ([dc:3], [dc3p] & [dc:3p] all do the same). [dc3-6] - Show 3 to 6 paragraphs randomly per page load ([dc:3-6], [dc3-6p] & [dc:3-6p] all do the same). [dc3w] - Show 3 words ([dc:3w] does the same). [dc3-6w] - Show 3 to 6 words randomly per page load ([dc:3-6w] does the same). <End update on tags.>
      If you think it might be useful, you can download it from GitHub and give it a try.
