1. Bloggers may use different words to invite guest authors for their blog. Here's a list of some common phrases bloggers use to invite people to guest post:
- "Submit a guest post" / "Submit post" / "Submit blog post"
- "Add blog post"
- "Submit an article"
- "Suggest a guest post"
- "Send a guest post"
- "Send your post"
2. Whilst quotation marks may be for better search results targeting, take advantage of wildcard (*) operator, as some guest invitations can be slightly different. For example, a blogger may write "Send us your post" instead of "Send your post"
3. Use OR and ~ operators to better describe your niche. For example, your blog may be about money, saving, etc. Obviously, the more words you use, the less search results will be returned.
To get broader but still relevant results, use the OR operator between the words, for example: "money OR saving OR frugality" (i.e. instruct Google to search for any of the words; if we're interested in guest blogging on sites covering any of these topics)
Use the ~ operator before a word that may have many synonyms (related words), for example: "~money" search will include words like "currency", "finance", "financial", etc.
