* Hello,
* this seems a fantastic plugin and it already does a great job in terms of meta/
keywords / content density & ratio scan. Keep up the great work!
* That said, all of my posts have been flaged with less than 75/100 SEO score because
they all get 24 HTML errors due to the following:
* **209: Tag header invalid
210: Tag nav invalid 272: Tag main invalid 276: Tag
article invalid 278: Tag header invalid 283: Tag time invalid 283: Tag time invalid
324: Tag nobr invalid 326: Tag footer invalid 380: Tag nav invalid 393: Tag aside
invalid 411: Tag aside invalid 428: Tag aside invalid 467: Tag aside invalid
512: Tag aside invalid 535: Tag aside invalid 548: Tag aside invalid 553: Tag
aside invalid 556: Tag aside invalid 560: Tag aside invalid 576: Tag footer invalid
579: Tag nav invalid
* Notice that they’re all HTML5 elements flagged as invalid, making me think that
the issue is lying around there. First thing I thought was, “Am I giving wrong
NS/DTD info?” but they seem to be fine.

* Sample post (giving a 72/100 score, basically everything OK but the above HTML“
errors”):

* Please let me know, I’m eager to give 5 stars to your plugin as soon as I’ll
get rid of this odd behaviour.
* Thanks

* Hello,
* I know that issue exists. In coming 2-3 days a new update v2.1 will be launched.
That feature has been removed in 2.1. Score calculation has also been improved.
* Please wait for a few days till launch. I’ll notify you in this thread.

* Hello and thanks, did 5 stars.
* A couple questions:
* – Why the SEO Server scan is saying that Cache is missing? I use WPTotalCache
plugin and its Cache Enabled timestamp check seems to be ok. Am I missing something?
* – Why the SEO Server scan is saying that WWW Resolve is missing?
* If you have a FAQ page explaining how these checks are performed and/or suggesting
fixes, please let me know.
* Anyway, thanks for the great work.

* 1. Cache is taken from header response key Cache Control.
2. WWW resolve is
seen by checking redirecting the page url versions.
* But bugs, as you know are hard to predict in so many different types of usage
environments.
Bug solving process is going on. Will soon release new updates
when they are done. A detailed documentation will come soon. Thanks for your
feedback.
