[Sam09schulz]

HI,

i have changed some h1 and h2 , changed and added paragraphs,fixed plagiarism,grammar and added some pics with alt text,

I have just done it today,

I am ranking on second page

QUESTION-1 is it gonna affect my 2 months SEO efforts?

QUESTION -2 Do I have to submit sitemap to google again?

QUESTION-3 does changing content on the site frequently hurts SEO?

Structure like a theme dont change the content, so yes you can safely change that. The URL's will remain the same as well so that shoud'nt cause an issue at all.

thanks jeroen for clearing things up.i really appreciate your help

and if i change my websites theme, lets say its a primer theme from wordpress and i want to choose theme from themeforest , is that gonna change the structure.

can u explain other than adding a page what else will count as changing structure.?

No that's content. Adding a page is extending your site structure.

any reference link you can share, because i dont see my answers cleared up.

what do u mean by site structure , lets say if i add pictures or videos, is that structure change?

1: If done right and google picks it up as it should you should see some gains for just updating your website.

2: you only have to submit a sitemap if you made physical changes to your website structure and pages, meaning that if you have'nt changed any of that you dont need to. A sitemap is just an index on how your website related to pages looks like.

3: See answer one.
