Hi, ive had a new website up and running for about a month now. Only one of my posts so far has been indexed.

I am using the yoast premium plugin.

If I buy CrawlWP, will this interfere with my posts and sitemap?

I only have about 8 posts so far that are published.

Also, will this type of software be penalised by Google? I saw something on another tool a while ago that this type of tool could be an issue?

Thanks
