The document summarizes optimizations made to improve the page speed scores of a website. Key changes included: 1) Optimizing image dimensions by adding width and height attributes. 2) Leveraging browser caching by adding expiration headers for images, CSS, and JavaScript files. 3) Enabling gzip compression via .htaccess modifications. 4) Specifying a Vary: Accept-Encoding header to improve compression. These changes resulted in page speed scores increasing from the 30s-70s to over 90 on various tools.

1. Website:kakadunationalparktours.com.au

2. 1) GTMetrix:[before]

3. b) YSlow[before]:
2) google page speed[before]:

5. 3) Google Mobile Test:resourcesare blocked –thisis howgoogle bot(whichisresponsible formobile siteranking)seesthe site.

8. Solution:whenIlookedat‘robots.txt’(fromCPanel access) whatInoticedasfollows:

9. I have deleted‘disallow:Images’.Becausewe needImage optimization. Thenwhatwe observe asfollows:

10. FinallyIreducedmanydisallowedresourcesandfinal robots.txtremainsasbelow:

11. Andfinallythe outputremainsasbelow:

12. Nexttaskwill be:Since newresources(Imagesinparticular):make anewsitemapfromScreamingFrogandsubmittoall those 3 webmasters.??
Solution:

13. (1) RunScreamingFrog again(Nowobserve mostof themare not blockedfromrobots.txt -  )
(2) Bothsitemap.xml andimages_sitemap.xml are submittedto3 webmastertools.(ingooglewebmaster,theywereresubmitted)
4) StructuredData TestingTool [before]:NOstructureddatapresent

14. 5) Screamingfrog:

15. 6) webmaster[before]:
Google:Yes
Bing:yes
Yandex:yes – no sitemapsubmitted [added–after]
PAGESPEEDRECOMMENDATIONS:
1) SpecifyingImage Dimensions:
Before:

16. Solution:

17. Wentto ‘Modules’toidentifywhere imageswere mentioned:
Pickedanexample module:

18. Look at the <img> code and update widthandheight.
Like below(afterchanges):addedwidthandheighttags.

19. Alsowe movedsocial iconsfromanothersite (stone-pavers.com.au)tothis site (forgainingspeed).

20. Finallywe achieved:‘scaledimage dimension’from9 to 64 (the existingnon-dimensionimagesare externalsites’whichwe can’tdoanythingfurther) as
follows:

21. [] Leverage BrowserCaching:
Addedtohtaccess:
## EXPIRES CACHING ##
<IfModule mod_expires.c>
# Enable expirations
ExpiresActiveOn
# Default directive
ExpiresDefault "access plus 1 month"
# My favicon
ExpiresByType image/x-icon "access plus 1 year"
# Images
ExpiresByType image/gif"access plus 1 month"
ExpiresByType image/png "access plus 1month"
ExpiresByType image/jpg "access plus 1month"
ExpiresByType image/jpeg "access plus 1 month"
# CSS
ExpiresByType text/css "access plus 1 month"
# Javascript
ExpiresByType application/javascript "access plus 1 year"
</IfModule>
## EXPIRES CACHING ##

22. Andthenthe value improvedfrom32 to 88:

23. [] Image optimization:

24. Resultsimprovedfrom36to 96
[] Enable gzipcompression:
Addedfollowingcode tohtaccess:
# ----------------------------------------------------------------------
# Gzip compression
# ----------------------------------------------------------------------
<IfModule mod_deflate.c>
# Force deflate for mangled headers developer.yahoo.com/blogs/ydn/posts/2010/12/pushing-beyond-gzipping/
<IfModule mod_setenvif.c>
<IfModule mod_headers.c>
SetEnvIfNoCase ^(Accept-EncodXng|X-cept-Encoding|X{15}|~{15}|-{15})$ ^((gzip|deflate)s*,?s*)+|[X~-]{4,13}$HAVE_Accept-Encoding
RequestHeader append Accept-Encoding "gzip,deflate"env=HAVE_Accept-Encoding
</IfModule>
</IfModule>
# Compress all output labeled with one ofthefollowing MIME-types
<IfModule mod_filter.c>
AddOutputFilterByTypeDEFLATEapplication/atom+xml
application/javascript

25. application/json
application/rss+xml
application/vnd.ms-fontobject
application/x-font-ttf
application/xhtml+xml
application/xml
font/opentype
image/svg+xml
image/x-icon
text/css
text/html
text/plain
text/x-component
text/xml
</IfModule>
</IfModule>
Andperformance jumpedfrom75 to97 Overall rankingprogressedto91 out of 100.

26. [] SpecifyaVary: Accept-Encodingheader:

27. Afteraddingthe followingcode,itjumpedfrom83to 100:
<IfModule mod_headers.c>
<FilesMatch ".(js|css|xml|gz)$">
Header append Vary: Accept-Encoding
</FilesMatch>
</IfModule>
