Nobody refused your edits, they are still there. The question owners have done nothing at all here.
What actually happened is that the questions you've been editing are being automatically deleted since even with your edit they are still poor quality questions.
When a post is deleted any increase (or decrease) in reputation you got from that post is removed as the post no longer contributes to helping anyone and also to try to encourage people to work on salvageable posts rather than unsalvageable ones.
If the questions you see are poor, downvote them and/or vote/flag them for closure unless you can fix them not to be poor.
In addition you're not really editing the questions to improve them you're just retagging them. Retagging can be useful but you need to fix the whole question if it needs an edit and remember not to bother if you're not going to end up making the question both on-topic and useful.

This question is about SEO which is off-topic at Stack Overflow. Please read "Which SEO questions should be closed as non-programming/non-admin?" to better understand when SEO questions are acceptable to ask here (most are not) and where you might be able to get assistance. Next time, please heed the warning and avoid asking non-programming related SEO related questions here.
there really is no way to save that question by editing it.
here you did try to improve the question but what does
Any help will be much appreciated.
add? Why leave that in, it's just fluff. There's also a link to an image you could have inlined and worst of all no code, just a description of what they have coded, you really can't fix that ommission.
