I have a static site that was mounted a long time ago which are .Aspx files. (It's only in ASPX because I use it in the contact form).
My question is simple: "It pays to convert my site .Aspx to .Html? ".
I want SEO better to be recognized by google thefts, .Aspx is worse or equal to .Html ?
Probably not, SEO takes into account whether the URL is well written / intuitive and descriptive, whether it is .html or .aspx or .foobar (it is possible to customize) will not influence.
I think that at most some sites will "type" url type .php or .aspx or .jsp to .html (url_rewrite ) so people do not know what technology site uses.
A "better" (more intuitive) url would look something like:
http://site/artigo/seo-de-html-vs-aspx.aspx
What does not differ much from this:
http://site/artigo/seo-de-html-vs-aspx.html
Still not for SEO but rather to make the user's life easier, something like this would be ideal:
http://site/artigo/seo-de-html-vs-aspx
You can not affirm the behavior of BOTs, much less say that url_rewrite will have better rank in Google and related, so urls are just one of the many points needed to rise in rank, from experience I tell you that well-written URLs are better, but they do not make you stand in front of other sites, as there are other factors with much greater weight.
Take into account that google's BOT is changing, you can not say anything precisely.
Good morning Jackson,
I'm not an SEO expert but from what I understand of the tool google uses the links to perform the indexing, so if your address is a valid address on the internet it does not matter if it's aspx, html, php and others. To understand better take a look at this link link because the guy gave a summary in the operation.
For better indexing and appear in the top positions in a query there are several companies specialized in SEO that can assure you a better ranking. You can also study the techniques and try to apply yourself, some tips can be found at link
About converting your site will depend a lot on your need, in case the current technology does not meet your demand is worth it, otherwise I suggest only you make a change to make your views responsive, that is, adapting to the device. This makes the environment more user friendly than a smartphone or tablet.
I hope I have helped;)
