Are there any tools or resources available to help with PDF submission for SEO purposes?

Hi Piper! You're smart to be thinking about how to optimize PDFs for better search engine visibility. PDFs can be quite valuable for SEO if you go about it the right way.

When it comes to actually submitting those PDFs to get them indexed and ranked, you have a few good tool options. Google Search Console is a great place to start - you can use the URL Inspection tool to manually submit PDF URLs and request indexing.

Another approach is creating a dedicated PDF sitemap and submitting that to Google. There are online generators that can help put together a sitemap file listing out all your key PDFs. Properly linking to PDFs from your main website can also help search engines discover and understand their relevance.

Beyond just submission, there are some other handy resources for optimizing the PDFs themselves for search. Adobe Acrobat allows you to convert PDFs into HTML or plain text formats that are easier for crawlers to digest. There are WordPress plugins like RankMath that can automatically optimize your PDFs with metadata, sitemaps, internal linking and such.

The goal is to make your PDFs as accessible, crawlable, and relevantly interlinked as possible. Sprinkle in keywords throughout your PDF content, just as you would do with any other content. Social shares of PDF links can provide a little extra visibility boost too.

So in summary - Google's tools, sitemaps, internal linking, conversion to searchable formats, keyword optimization, and a few WordPress plugins are your friends here.
