14 14 == Description ==
15 15
16 -WP-Optimize Cache is a revolutionary, all-in-one WordPress performance plugin that caches your site, cleans your database, compresses your images.
16 +MORE THAN A CACHING PLUGIN
17 17
18 -Our cache feature is built around the world’s fastest caching engine. This simple, popular and highly effective tool has everything you need to keep your website fast and thoroughly optimized!

20 +It does this in four clever ways:

22 -It does it in three clever ways:
22 +<strong>1. It caches your site</strong>
23 23
24 -* It allows you to clean and optimise your database.
25 -* It gives you the option to compress your images.
26 -* It allows you to cache your pages, for super fast load times (read more caching information below).
24 +Caching is the process of storing a temporary HTML version of your site on the server so it can be retrieved more quickly for the user.
27 25
28 -It also enables you to minify and asynchronise CSS and JavaScript (aka. "defer CSS JavaScript").
26 +It's a sure-fire way to ensure web pages load at lightning-fast speed. Turn it on in just one click.
29 27
30 -Extensive tests show the cache feature alone can make WordPress sites at least as fast as any other caching or speed plugin available and often faster. But when you combine the cache with the database optimization, image compression features and minify, the speed difference with alternative solutions is significant.
28 +<strong>2. It compresses images</strong>
31 29
32 -<strong>NEW:</strong> The built-in minify feature adds another layer of optimization, reducing the size and number of requests to your server.
30 +Large images can really impact page speed load times. WP-Optimize makes it easy to identify and compress images to your preferred lossy / lossless settings in a couple of clicks.
33 31
34 -= 1. Cleans the database =
32 +<strong>3. It cleans the database</strong>
35 33
36 -Your WordPress database stores everything that you need for your website – plus many things that you don’t. WP-Optimize Cache clears out all of this unnecessary data, cleans up your tables and even retrieves space lost to data fragmentation.
34 +Your WordPress database stores everything that you need, plus some things that you don't. WP-Optimize cleans and optimizes the database to speed up your site and save server resources.
37 35
38 -Mobile-friendly and incredibly simple to use, it:
36 +<strong>4. It minifies</strong>
39 37
40 -* Removes all unnecessary data (e.g. trashed/unapproved/spam comments, stale data) plus pingbacks, trackbacks and expired transient options
41 -* Compacts/de-fragment MySQL tables with a button-press
42 -* Detailed control of which optimizations you wish to carry out
43 -* Carries out automatic weekly (or otherwise) clean-ups
44 -* Retains a set number of weeks’ data during clean-ups
45 -* Performs optimizations without the need for running manual queries
46 -* Automatically trigger a pre-optimize backup via <a href="https://updraftplus.com">UpdraftPlus</a>
47 -* Show database statistics and potential savings
38 +On top of its three main features, WP-Optimize Cache also has the more advanced minification feature.
48 39
49 -<strong>Why is this important?</strong>
40 +Together with caching, minification dramatically improves performance and page speed load time.
50 41
51 -* The tables in MySQL (the database that WordPress uses) will, over time, become inefficient as data is added, removed, moved around. Asking MySQL to optimize its tables every now and again will keep your site running as fast as possible. It won’t happen by itself.
52 -* Every-time you save a new post or pages, WordPress creates a revision of that post or page. If you edit a post 6 times you might have 5 copy of that post as revisions. This quickly adds lots of rarely-used data to your database tables, making them unnecessarily bloated, and slower to access.
53 -* There might be thousands of spam and un-approved comments in your comments table, WP-Optimize Cache can clean and remove those in a single click.
54 -* WP-Optimize Cache reports which database tables have overhead and wasted space to allow you to reduce them.
55 -* Automatically cleans your database every week and respects the “Keep last [selected number] weeks data” option.

58 -= WP-Optimize Cache helps you to: =
46 +WP-Optimize automatically and optimally configures itself for your WordPress site. Turn it on in one-click or refine its settings if you prefer.
59 47
60 -* <strong>Make space:</strong> When you edit a post or page on your website, WordPress automatically saves the new revision to the database. If you edit things a few times (and particularly if the post is long), your database soon gets clogged up with old revisions that just sit there, taking up valuable space. WP-Optimize Cache removes these unnecessary post revisions, freeing up valuable Megabytes of data and increasing speed and efficiency. It also cleans up your comments table, removing all the spam and un-approved comments that have built up with a single click.
48 +<strong>More cache features:</strong>
61 49
62 -* <strong>Take control:</strong> WP-Optimize Cache reports on exactly which of your database tables have overhead and wasted space, giving you the insight, control and power to keep your website neat, fast and efficient.
50 +* <strong>Cache preloading:</strong> This feature emulates a visit to your site, meaning cached files are served straight away, speeding up your site from the very first visit.
63 51
64 -* <strong>Keep it clean and fast:</strong> Once enabled, WP-Optimize Cache can run an automatic clean-up on a schedule, keeping a selected number of weeks’ data, according to your specification.
52 +* <strong>GZIP Compression:</strong> When the server isn't configured to do so, WP-Optimize delivers HTML, CSS and JS files to the user's browser as smaller, compressed files, reducing the size of pages and style sheets by up to 90%!
65 53
66 -= 2. Compresses images =
54 +* <strong>Preload key requests:</strong> Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster <strong>[Premium]</strong>.
67 55
68 -Loading large images is often the biggest culprit in slowing your site’s loading time.
56 +<strong>Use cache settings to:</strong>
69 57
70 -WP-Optimize Cache has an image-compression tool that uses cutting-edge lossy compression techniques to convert large images (which take a long time to load up) into compressed files saved in your image library, where they can be uploaded in an instant.
58 +* <strong>Serve cached content to logged in users:</strong> Turn this on if content stays the same for logged in users (or turn on and exclude URLs where content does change e.g. my account areas).
71 59
72 -It enables you to compress PNG, JPG, GIF, BMP and TIF pictures up to 5MB in size, and it’s packed with other useful features, including:
60 +* <strong>Exclude content from cache:</strong> Exclude by URL, conditional tags, browser agent strings or list cookies that should prevent caching when set (advanced user settings).
73 61
74 -* <strong>Bulk compression</strong>, allowing you to compress multiple existing images at the same time.
75 -* <strong>Intelligent, multi-pass lossy compression algorithm</strong>, which gives you twice the compression with much less loss of quality.
76 -* <strong>‘Restore Originals’ function</strong>, which allows you to retrieve or revert back to your original images at any point.
77 -* <strong>Auto-compress function</strong>, which automatically compress images as they’re added to the site.
78 -* <strong>EXIF Data-Keeping</strong> means image information is retained even once the image is compressed.
62 +* <strong>Deliver device-specific cache:</strong> Serve separate cache files to desktop and mobile devices . This ensures that responsive features e.g. desktop and mobile menus are cached separately and served correctly.
79 63
80 -This WordPress plugin allows you to increase your page speed without compromising the image quality.
64 +* <strong>User per role cache:</strong> Useful if your website delivers different content to different user roles. e.g. an e-commerce site that displays different content to resellers or consumers <strong>[Premium]</strong>.
81 65
82 -= 3. Caches pages =
66 +* <strong>User specific cache:</strong> Serves separate cache files to individual users. Useful for websites with personalised content e.g. Learning management systems <strong>[Premium]</strong>.
83 67
84 -<strong>Depending on your setup, page caching can be what makes the biggest difference to your website's speed and performance.</strong>
68 +* <strong>Cache purging permissions:</strong> Select which user roles are allowed to purge the cache e.g. admin only or perhaps a 'teacher' role in an LMS setting only <strong>[Premium]</strong>.
85 69
86 -Caching involves keeping dynamic data in a temporary storage area so that it can be retrieved in an instant. Caching is a sure-fire way to ensure that web pages load at lightning-fast speed.
70 +== 2. COMPRESS IMAGES ==
87 71
88 -Practically, our powerful yet simple cache feature generates the cache when a user visits any page or post on your site. WordPress processes the dynamic php files to generate that page, and we save it into a static html file in the cache folder, so that when the next user visits, the page is cached and doesn't need processing. This caching results in a much faster loading time, and gives a slight break to your server. So caching increases speed and performance while reducing the server's use of resources.
72 +* <strong>Lossy or lossless compression options:</strong> Choose between maximum space saving, best image quality or somewhere in-between.
89 73
90 -With minimal configuration, caching your site with WP-Optimize Cache is easy to do thanks to a load of useful features, including:
74 +* <strong>WebP conversion:</strong> Recommended by Google, WebP can achieve up to 34% smaller file sizes compared to JPEG and up to 26% compared to PNG.
91 75
92 -* <strong>Cache preloading</strong> to ensure the cache is always ready and loaded.
93 -* <strong>Gzip compression</strong> of HTML, JavaScript, and CSS to reduce site load time.
94 -* <strong>Device-Specific cache</strong> to ensure the optimized page version is always served.
95 -* <strong>Advanced cache exclusion rules</strong>, so that you can cache almost anything by excluding logged in users, specific URLs or cookies.
96 -* <strong>Browser Cache</strong> to instruct client browsers to reuse cached resources (HTML, CSS, JS, images) if no changes were made since the last request.
76 +* <strong>Auto-compress:</strong> Check a box and every new image you upload will automatically be compressed to your preferred lossy / lossless settings.
97 77
98 -= Minify and combine CSS and JavaScript =
78 +* <strong>Bulk compression:</strong> Compress every existing image on your site with the press of a button.
99 79
100 -On top of its three main features, WP-Optimize Cache also has the more advanced <strong>minification</strong> feature. Combining and minifying your site's assets will reduce the number of requests to your server (by combining them) and reduce their size (by minifying their content).
80 +* <strong>Restore original:</strong> Gone too far? Revert images back to their original in one click.
101 81
102 -Together with caching and Gzip compression, this will improve the performance and time to "first contentful paint".
82 +* <strong>Retain EXIF image data:</strong> Check a box to retain EXIF image data during compression.
103 83
104 -The minify feature also enables you to defer CSS and JavaScript. Deferring CSS and JavaScript allows you to load non-critical assets after the main page load, resulting in an apparent speed gain. Minifying and deferring CSS and JavaScript also makes Google PageSpeed Insights happy!
84 +* <strong>Lazy Load:</strong> Webpages load much faster by loading web parts gradually, when they're needed vs simultaneous loading of everything, all at once <strong>[Premium]</strong>.
105 85
106 -<strong>Overall WP-Optimize brings the best cache and optimization technology together in a single seamless plugin to make your WordPress site fast, lean and efficient.</strong>
86 +* <strong>Delete orphaned images:</strong> Identify and delete unused images from your Wordpress website, saving disk space <strong>[Premium]</strong>.
107 87
108 -= WP-Optimize Cache Premium =
88 +* <strong>Delete unused image sizes:</strong> WordPress creates multiple sizes for every uploaded image causing the uploads folder to become bloated. Scan for image sizes not in use and remove them to save further disk space <strong>[Premium]</strong>.

94 +
95 +* <strong>Schedule clean-ups:</strong> So you can set and forget. Choose from daily, weekly, fortnightly or monthly.
96 +
97 +* <strong>Flexible clean-up schedules:</strong> You may wish to optimize database tables more frequently than you remove unapproved comments (for example). Choose the specific time and day when tasks should run <strong>[Premium]</strong>.
98 +
99 +* <strong>Retain a set number of weeks' data during clean-ups:</strong> Just in case you need to retrieve something.
100 +
101 +* <strong>Back up before clean-ups:</strong> If you delete something you shouldn't, restore it in a couple of clicks with UpdraftPlus.
102 +
103 +* <strong>Power tweak - Turbo boost for WooCommerce:</strong> Unique to WP-Optimize, this power tweak boosts performance by replacing a slow query in WooCommerce with two much more efficient queries. E-commerce sites transacting high numbers of orders stand to gain here <strong>[Premium]</strong>.
104 +
105 +* <strong>Power tweak - Boost performance by indexing the postmeta table:</strong> This unique power tweak works by allowing the WordPress postmeta table to be indexed, improving performance <strong>[Premium]</strong>.
106 +
107 +
108 +== 4. MINIFY AND COMBINE HTML, CSS AND JAVASCRIPT ==
109 +
110 +* <strong>Minify in just one click:</strong> Minifies HTML, JavaScript and CSS. Toggle on or off or customise each one under 'settings'.
111 +
112 +* <strong>Customise minification:</strong> Minify only (removing unnecessary code e.g line breaks and white spacing) or minify and merge. Apply the same or different settings to HTML, CSS and JavaScript.
113 +
114 +* <strong>Asynchronous loading:</strong> Choose non-critical CSS and JavaScript files to load in the background and independently of other resources e.g. analytics or pixel scripts. Loading asynchronously eliminates render blocking and improves page speed.
115 +
116 +* <strong>Exclude files from being minified:</strong> Specify CSS and JavaScript files to exclude from minification.
117 +
118 +* <strong>Optimize fonts:</strong> Optimize Font Awesome and Google Fonts. Inline the font files, inherit from CSS settings or load CSS / Javascript asynchronously instead.
119 +
120 +* <strong>Preload assets:</strong> WP-Optimize visits each web page on your site so the code is minified and preloaded for real life users, right from their very first visit.
121 +
122 +* <strong>Preload key requests:</strong> Recommended by Google to improve page speed times. Critical resources (things like font files) get loaded first, so the page loads much faster.
