Make Every Post Look Professional Before You Hit Publish
TL;DR: Ugly link previews, missing meta tags, and random hashtags sabotage your social media reach. Free tools for Open Graph preview, Twitter Card generation, hashtag research, meme creation, and social-ready image formatting fix all of that in minutes. I doubled my LinkedIn click-through rate just by fixing how my links displayed.
I shared a blog post on LinkedIn last year that I'd spent two weeks writing. Great headline, solid content, genuine insights. The link preview showed a broken image, a truncated title, and a description that read "undefined." It looked like spam.
Three people clicked it. Three.
The next week I shared a post with a properly configured Open Graph image, a clean title, and a compelling description. Same audience, similar topic. 340 clicks.
The content was comparable. The packaging made all the difference. Here's how to package every post properly before you share it.
Preview Before You Post
Open Graph Preview
The Open Graph Preview tool shows exactly how your URL will appear when shared on Facebook, LinkedIn, Slack, Discord, and other platforms that read OG tags. You see the image, title, and description before anyone else does.
I check every URL in this tool before sharing it anywhere. If the preview looks wrong, I fix the OG tags on the page and recheck. This single habit eliminated embarrassing "broken preview" posts from my feed entirely.
The most common problems the preview catches: missing og:image (shows a generic placeholder or nothing), truncated og:title (too many characters), and an og:description pulled from random page text instead of the meta description.
Twitter Card Preview
Twitter handles link previews differently from other platforms. The Twitter Card Generator creates the correct meta tags for Twitter's summary_large_image format, which displays your link with a big, eye-catching image card.
Without proper Twitter Card tags, your links appear as plain text URLs. With them, every shared link becomes a visual card with your headline, description, and featured image. The engagement difference is significant.
Meta Tag Preview
The Meta Tag Preview shows how your page appears in Google search results specifically. Your social media links often get secondary traffic from search, so making sure your Google listing looks sharp matters too.

Generate the Right Meta Tags
If your link previews look wrong, the fix is usually missing or misconfigured meta tags. Two tools handle this:
The SEO Tags Generator creates a complete set of meta tags including Open Graph and basic SEO tags. Copy the generated code, paste it into your page's <head> section, and your previews will work correctly everywhere.
The Twitter Card Generator focuses specifically on Twitter's meta tag format. Use both tools together for complete social coverage.
Hashtag Strategy
Generate Relevant Hashtags
The Hashtag Generator creates platform-specific hashtags for Instagram, Twitter, LinkedIn, and TikTok. Enter your topic, and it suggests tags based on relevance and search volume.
I generate hashtags for every post rather than reusing the same set. Platforms penalize repetitive hashtag use, and different content topics deserve different tags.
Platform-specific counts that work for me:
- Instagram: 8 to 12 hashtags (mix of broad and niche)
- Twitter/X: 1 to 2 focused hashtags
- LinkedIn: 3 to 5 professional hashtags
- TikTok: 3 to 5 trending plus niche tags
Create Shareable Visual Content
Meme Generator
The Meme Generator creates custom memes with your images and text. Memes aren't just entertainment. For brands with the right voice, they generate more shares and engagement than polished graphics.
I use memes sparingly in my professional feed, but when the topic fits, they outperform every other content type by a wide margin. The key is relevance and timing.
Fake Chat Generator
The Fake Chat Generator creates realistic chat screenshots for iOS, Android, and WhatsApp. Content creators use these for tutorials, product demos, and storytelling posts that show conversations in context.
I've used it to create "before and after" customer service examples for training content. The chat format is instantly relatable and easy to scan.
Image Optimization for Social
Social platforms compress uploaded images, sometimes badly. Uploading properly sized and compressed images gives you more control over quality.
My image prep workflow for social media:
- Resize images to platform dimensions (1200x630 for OG images, 1080x1080 for Instagram)
- Compress to reduce file size without quality loss
- Convert to the right format depending on the platform's preference
The full image optimization guide is in my post on compressing images for faster websites. The same principles apply to social media images.
Create QR Codes for Offline-to-Online Bridging
Print materials, event banners, product packaging, and business cards all benefit from QR codes that link to your social profiles or latest content.
The QR Code Generator creates scannable codes in seconds. I put QR codes on my business cards linking to my LinkedIn profile. At conferences, people scan instead of typing my name into a search bar. My full guide on QR code strategies covers more use cases.
Fun Text Effects for Posts
Stand out in crowded feeds with text that catches the eye:
- Glitch Text Generator creates corrupted "Zalgo" text for Halloween posts, horror content, or attention-grabbing headlines
- Bubble Text Generator wraps letters in circles for playful, bubbly captions
- Upside Down Text Generator flips text for curiosity-driven engagement
Use these sparingly. One post with glitch text is intriguing. Every post with glitch text is annoying.
My Pre-Publish Checklist for Social Media
Before I share anything:
- Open Graph Preview to verify the link card looks right
- Twitter Card tags confirmed for X/Twitter specifically
- Image resized and compressed for the target platform
- Hashtags generated and customized for the post topic
- Copy checked for grammar with the Grammar Checker
- URL shortened if needed, with the destination verified via URL Unshortener
Six steps. Five minutes. The difference between a post that gets 3 clicks and one that gets 300.
FAQ
Why does my link preview show the wrong image on Facebook? Facebook caches OG data. After fixing your tags, use Facebook's Sharing Debugger to force a re-scrape of your URL. The Open Graph Preview tool shows what your current tags will produce once caches clear.
Do I need different images for different platforms? Ideally, yes. OG images work best at 1200x630 (landscape). Instagram posts are 1080x1080 (square). Twitter header images are 1500x500. At minimum, a 1200x630 OG image covers Facebook, LinkedIn, and Twitter acceptably.
How do I know which hashtags are performing? Most social platforms offer basic analytics showing impressions and engagement per post. Track which hashtag sets correlate with higher reach. The Hashtag Generator gives you relevant starting points to test.
Can I use the Meme Generator for brand content? Yes, if it fits your brand voice. B2C brands, tech companies, and media brands use memes successfully. B2B and highly regulated industries should be more cautious with humor.
Should I share the same content across all platforms? Adapt each post for the platform. LinkedIn favors professional commentary. Twitter favors concise observations. Instagram favors visual-first content. Same topic, different packaging.
